Teeth whitening

Not everyone can boast of naturally white teeth. But today this is not a particular problem. Many dental clinics successfully perform teeth whitening. Understanding numerous methods, it is important to know about the main indications and contraindications, and then you can find the most suitable one for yourself. The best way teeth whitening.

When should you think about teeth whitening?

Each patient needs to understand that the final result may differ from the desired one. The color of teeth is very individual, which means the degree of lightening will also be individual.

Teeth enamel can be whitened in all cases if the pigmentation is superficial. Most browning comes from food coloring. A special residue remains from cigarettes, coffee, strong black tea, some types of carbonated drinks, sweets and chocolate. The natural yellowness of the enamel can also be successfully eliminated using modern methods.

The presence of deep pigmentation often indicates non-carious lesions of the hard tissues of teeth. In some of them, the whitening procedure is contraindicated.

Indication will be a thick layer of enamel, absence of hypersensitivity of the teeth, correctness in the anatomical structure of the hard tissues of the tooth. The patient's age plays a special role. Whitening is not recommended for persons under 16 years of age. Before this age, the enamel has not yet undergone complete calcification and the natural color of the teeth has not stabilized. This can lead to high sensitivity and even disruption of its integrity.
The enamel undergoing lightening should not be affected by caries, since the procedure will intensify the course of the carisogenic process.

Contraindications to teeth whitening

It is not advisable to carry out procedures in the following cases:

Intolerance to drugs used during various techniques;

High sensitivity of teeth due to the structural features of the pulp chamber. This is mainly due to its increased size. Such teeth contain a thin layer of hard tissue, which causes their pathological hypersensitivity to irritants;

Exposure of the neck of the crown or root;

Pregnancy and lactation;

Expressed allergic reactions, especially for medications;

The presence of a large number of orthopedic structures in the oral cavity. Some methods may simply damage them;

Periodontal diseases, the presence of tartar, diseases of the oral mucosa;

The presence of severe somatic diseases (tumors, stage 3 hypertension, type 2 diabetes mellitus, hyperthyroidism).

The presence of enamel cracks and multiple carious defects.

Teeth whitening in dentistry

Professional teeth whitening is the key to beauty and health. Indeed, only a dentist can competently select and professionally carry out any manipulation. The achieved results always please the patient and last for a long time, even despite the aggressive environment of the oral cavity.

Types of teeth whitening

The most modern methods of teeth whitening today are:

1. Air Flow technique (mechanical teeth whitening)

The essence of the method is to qualitatively remove all pigmented plaque from the enamel surface. For this, special devices are used. They deliver a mixture of air, water and fine abrasive powder under high pressure to the desired area of ​​influence.
Tartar, hard pigmentation, and soft food plaque are removed. This is more like, since the enamel itself is not bleached. But the teeth become an order of magnitude whiter and this suits many patients.
The advantages of the method are that there is no chemical exposure on hard tissues, which means their strength is preserved. In the future, there will be no increased sensitivity to irritants. Whitening is carried out in one session. This results in significant savings in time and money.
The cost of such teeth whitening is not high - within 3,000 rubles, depending on the location of the clinic and its status. For example, in the capital the price can reach 5,000 rubles, while in the provinces 3,000, this is already the limit.

2. Laser teeth whitening

The technology is simple and safe, absolutely harmless to enamel. A special teeth whitening gel is applied to the problematic surface of the teeth. It contains the active ingredient hydrogen peroxide.

After application, the gel is illuminated with a special lamp for several seconds. Teeth become 2-4 shades lighter in one session. Of course, the main advantage is the safety and durability of the result obtained. The effect of the procedure can last up to 5-7 years in adequate conditions. The most serious disadvantage is the cost. The price for laser teeth whitening ranges from 10,000 to 20,000 rubles.

3. Ultrasonic teeth whitening

This is the most gentle teeth whitening, capable of making teeth several shades whiter. Ultrasonic teeth whitening is ideal for people who already have high enamel sensitivity. The effect is absolutely painless, the concentration of the special oxidizing agent is minimal.

The downside is that teeth whitening at the dentist takes about 30 minutes. It is impossible to achieve the desired result in one visit, so the dentist is visited several times. The applied gel ideally protects the enamel surface from mechanical destruction.
At the end of the procedure, the dentist performs polishing using a special paste. Its components easily penetrate microcracks in the enamel, tightly sealing them from the destructive effects of caries.

The cost of ultrasound exposure starts from 1000 rubles. for one row of teeth. For large volumes of work, the price reaches 7,000 rubles. for the entire service. The result lasts for about 1 year.

4. Photo teeth whitening

This technique is advanced in modern dentistry. It is based on a chemical reaction of exposure to a certain light flux and hydrogen peroxide. This reduces Negative influence peroxide on hard tissues.

There are three types of photobleaching:

■ Halogen exposure. Special lamps with halogen emitters are used. They have minimal thermal effect on fabrics.

■ Ultraviolet exposure. It is used only in teeth with strong and thick enamel, as it has a fairly strong thermal effect. The effect on teeth is very intense. Even in one visit it is possible to achieve high results. Teeth become 3-5 shades whiter.

■ LED exposure. Is the most in a safe way. It is often used for highly sensitive teeth, since the thermal effect is completely absent.

Step-by-step photobleaching

This type of procedure is performed only in the dentist's office. It takes 50-70 minutes. The teeth whitening procedure begins with cleaning the teeth from soft plaque and removing hard deposits. Then they begin to determine the color that will be after lightening. The dentist does this together with the patient.

Immediately before the manipulation soft fabrics isolated with a retractor. This is a special protective solution. The teeth are dried and an active gel is applied. It is distributed over the entire dental arch, which is then completely illuminated. Exposure time 10-20 minutes. The desired result is not always achieved the first time, so the process is repeated if necessary. No more than 6 exposures are allowed per visit. If even after this desired result is not achieved, then a second visit is allowed only after 7-10 days. During this time, home methods for lightening enamel are recommended.

The cost of photobleaching is quite high - up to 20,000 rubles. However, it is worth considering all the advantages of the technique, which will help save nerves and money from possible complications after other methods of exposure.

Modern photobleaching systems

Whitening systems represent a complex effect various types luminous flux and chemical substance. This ensures maximum effect with minimal investment of time and money. Modern dentistry offers the following types impacts:

Cold light Beyond Polus.

A uniquely made lamp combines two types of emitters that distribute LED and halogen flux. The lamp has an ultraviolet filtration system, which reduces the heating of tissues (this is a kind of cold teeth whitening).
Hydrogen peroxide is used with a concentration of 30-40%. The entire procedure has three cycles of exposure for 7-10 minutes. The full effect occurs after 14 days and lasts up to a year.

Luma Cool LED system.

The method combines the effects of LED streams and a high concentration of hydrogen peroxide, which is up to 40%. When exposed, cyclicity is used, 3 approaches, which last for eight minutes each.

Before manipulation, soft tissues are isolated with a special solution. It quickly hardens in air and subsequently reliably protects against the effects of hydrogen peroxide. After the procedure, slight sensitivity of the teeth appears. It goes away on its own in 3-4 days. If sensitivity is maintained, it is recommended to use pastes with a high content of fluoride and calcium. The resulting shades last for several years with proper oral care and regular visits to the dentist.

Ultraviolet system Zoom.

This technique is now the most popular. Teeth whitening with a zoom system has a traditional technique. A concentrated gel is applied to the teeth and illuminated with an ultraviolet lamp, thereby activating the gel and producing oxygen. Under ultraviolet rays, the gel and the enamel itself are heated - this allows oxygen to penetrate deeper into the tissue, which helps achieve best result. This action allows you to achieve color improvement up to 8 tones. This is mainly where its popularity lies.

Despite the obvious advantages, there are certain disadvantages. Heat during manipulation can cause disturbances in the structure of the enamel. The exposure time to ultraviolet rays lasts up to 1 hour or more, depending on final result. Storage possible within 10 days hypersensitivity to irritants.

5. In-canal teeth whitening

Intra-canal, intracoronal teeth whitening or endo-bleaching is a procedure for whitening a pulpless (non-living) tooth from the inside using a lightening gel. Endobleaching is indicated: when there is a change in the color of the tooth that occurs from the inside and is not amenable to external bleaching; in case of tooth trauma with hemorrhage into the pulp chamber; when filling tooth canals with coloring pastes (resorcinol-formalin - the crown and root acquire a pink tint, and after silvering - black); when a pulpless tooth darkens due to the death of the pulp (dental nerve) as a consequence of complications of the carious process (pulpitis and periodontitis); when dyes (tea, coffee, tobacco) penetrate through cracks in tooth enamel, leading to dentin staining.

Whitening of a pulpless tooth is carried out in the dentist’s office. First, the doctor must determine the cause of the tooth discoloration; it may be necessary X-ray examination to assess the quality of endodontic treatment and filling of the root canal, the absence of residual inflammatory process in it. Then the doctor removes the old filling and thoroughly cleans the tooth of the coloring substance, and, in order to prevent the bleaching substance from getting into the root canals, applies an insulating lining made of glass ionomer cement to them. The doctor installs a temporary filling, under which he places a whitening gel. After 2 weeks, the temporary filling and gel are removed and, if necessary, the whitening procedure is repeated until desired effect. 3-5 treatments may be required. When the desired whiteness is achieved, the dentist restores the tooth using modern composite materials. Repeated intra-canal teeth whitening is performed no earlier than after a year.

This method is the best for whitening teeth with fillings, it can be done on only one tooth, there is no need to grind down the tooth, and besides, it is painless. The disadvantage of endo-bleaching is that the tooth becomes even more fragile after the bleaching procedure, and therefore this method can be used no more than 4 times. Additionally, the whitening gel may not work on some filling materials. The price of intracanal teeth whitening ranges from 1000 to 3000 rubles. for one tooth.

6. Teeth whitening at home

Teeth whitening at home is a painstaking job that must be done daily to achieve the desired result. Home remedies for teeth whitening can be purchased at any pharmacy or online store.

Teeth whitening using trays and gels

Home teeth whitening systems involve the use of specially made trays. For the best impact, mouthguards can be made from an individual impression.
The system kit includes a gel to lighten the enamel and a fluoride-containing gel to strengthen it. Teeth whitening trays are worn for quite a long time - up to 10 hours a day. To reduce the appearance of unpleasant sensations from the effects of a whitening gel, it is alternated with a fluoride-containing one.

In the first sessions, the mouth guard is filled 1/3 full. Before putting it on, the teeth are thoroughly cleaned with fluoride toothpaste. It is necessary to ensure that the gel does not get on the gums. If this happens, it is immediately removed using cotton swabs or ear swabs. When adverse reactions it is necessary to reduce the amount of gel used and the exposure time.

The patient can carry out home teeth whitening at night or during the day, as is more convenient for him. The entire process must be under the supervision of a doctor. The procedure is lengthy, so you will have to visit the dentist more than once. These inconveniences are fully compensated affordable price. Such systems can be purchased for 500-700 rubles. Teeth whitening with a mouthguard is a budget solution with a good effect of lightening tooth enamel by 2-3 tones.

Teeth Whitening Strips

Teeth whitening strips consist of a thin, sticky material coated with a gel containing a small percentage of hydrogen peroxide. These teeth whitening products can be purchased at any pharmacy. They are glued to the teeth once a day for 5-30 minutes, the course is 7-28 days, depending on the concentration of the active substance and the sensitivity of your teeth. Teeth whitening strips lighten the enamel by 1-2 shades. The effect will last about 3-6 months with proper dental care. The strips have many disadvantages: they often do not stick well to the teeth; it is impossible to whiten all teeth, but only the front ones; increase the sensitivity of enamel and irritate the gums and oral mucosa; quite expensive, they can cost from 1500 to 3000 rubles. In addition, they can only be used when “healthy” tooth enamel is not thinned, otherwise there will be serious complications.

There are many companies that produce teeth whitening strips: Crest, DR.WHITE, Bright Light, Blisstees, Luster, Aquafresh, Rembrandt, Blend-a-med, Johnson & Johnson (Listerine Whitening).

The pencil is a container with a special gel, which is applied to dry teeth using a brush or sponge at the end of the pencil and left for several minutes. Then the gel is removed with a napkin, and the mouth is rinsed well. Just like teeth whitening strips, it contains a small percentage of hydrogen peroxide - 5% -10%. The effect is approximately the same as that of the strips; it should be used only with healthy tooth enamel. The price of a teeth whitening pencil is about 1000 rubles.

Toothpaste for teeth whitening

Choosing such a paste for the average person is often very difficult. Their huge number can confuse even a specialist.

Whitening pastes are divided into two groups: the first has a mechanical effect, the second has a chemical effect.

Mechanical lightening occurs from the effects of abrasives added to their composition. The most popular remains sodium bicarbonate or regular soda. In addition, silicon and aluminum oxide, as well as dicalcium phosphate, are added to the composition. They eliminate only superficial darkening and plaque. Their cost starts from 30 rubles.

Pastes with chemical components capable of influencing more deeply. This way the effect is more noticeable machining. Chemical teeth whitening acts slowly, but without pronounced negative consequences on hard and soft tissues. They contain extracts of pineapple, papaya, hydrogen peroxide, pentapotassium, tripolyphosphate and others. They are much more expensive in price than the first group. Some of them cost 200-300 rubles. Best pasta For teeth whitening it is chemical. They are often called premium pastes, which can lighten the enamel 1-2 shades higher. These pastes can even be used to whiten sensitive teeth.

7. Teeth whitening with folk remedies

All remedies used in folk medicine to make teeth brighter are based on natural products. Traditional methods of teeth whitening, compared to professional ones, bring minimal effect, but are available to everyone.

Teeth whitening with soda

First place goes to baking soda. Baking soda is used during routine brushing of teeth with toothpaste or separately from it. Its action is based on mechanical cleaning of the enamel surface. After several procedures, it does become brighter, but this is only due to the removal of hard pigmentation from its surface. Rough exposure to soda can thin the enamel and cause high sensitivity. Therefore, it is recommended to use it no more than once a week.

Teeth whitening with activated carbon

Activated carbon has the same effect. It can be chewed or applied to a toothbrush while brushing your teeth. Use is allowed only with strong and healthy enamel. The activated carbon tablet is quite hard, and when chewed, part of the enamel of the tooth crown can easily be broken off. The effect of teeth whitening with charcoal is not permanent, and complications can arise not only with the enamel, but also with the periodontium (the surrounding tooth tissue). Activated carbon can easily injure the gums and cause local inflammation.

Teeth whitening with hydrogen peroxide

At home, mouth rinses with hydrogen peroxide are used. But its concentration is small and does not give a pronounced effect. Only teeth with strong enamel can be wiped with hydrogen peroxide.

Teeth whitening with acids

Strawberries and lemon are often used as a source of acid. Teeth whitening with lemon is carried out by applying pieces of lemon to the surface of the teeth for a few minutes or rubbing lemon juice. Many people are not able to withstand this method for a long time. After the first signs of soreness appear, all procedures are stopped, and accordingly the effect is minimal.

Today we hear such types of teeth whitening as mechanical, ultrasonic, laser, photo whitening, intracanal, as well as whitening with pencils, trays, special strips, etc. To an unprepared person It may seem that there are just a lot of ways to lighten enamel, and that figuring it all out is very difficult.

In fact, everything is quite simple - all of the above methods of teeth whitening are essentially divided into chemical and mechanical.

Chemical teeth whitening is, simply put, the process of destroying colored organic compounds inside the enamel using special substances. In such cases, a certain chemical agent is always required that can destroy and discolor pigments (for example, oxidize them) that have appeared in the surface layer of tooth enamel over many years of smoking, drinking coffee, strong tea, red wine, etc.

Mechanical teeth whitening is, in fact, professional oral hygiene, which many dentists don’t even consider whitening (although the procedure gives a very pronounced visual effect). Imagine healthy white teeth, but covered in brown tartar and stained plaque. At mechanical removal After all these unwanted deposits, a person can again sparkle with a snow-white smile - but no one actually whitened his teeth (enamel).

Professional hygiene may involve ultrasonic teeth whitening using special devices and scalers, teeth cleaning with an Air-Flow device, and removing plaque with special pastes. The benefits of professional cleaning for ordinary person is that for a relatively low price you can kill two birds with one stone: rid your teeth of tartar and plaque that injures the gums, creating risks of caries, and at the same time “lighten” your teeth by a shade or more without directly affecting the internal structures of the enamel.

Mechanical “whitening” of teeth: principle of operation

As noted above, mechanical teeth whitening is a method of lightening them in which dental deposits (tartar, plaque) are removed, which ultimately leads to the return of the natural color of the teeth.

Often, those people who have been growing “smoker’s plaque”, “coffee drinker plaque” on their teeth for years, as well as conglomerates of stones (most often on the lower front teeth) have long forgotten what their teeth should normally look like. clean teeth. In such cases, you should not look for peroxide-containing pencils or teeth whitening strips, but focus, first of all, on professional oral hygiene - this will give a much greater effect.

Teeth whitening with Air-flow ultrasound

Among the mechanical methods of teeth whitening, the most common today is ultrasonic whitening. Despite the active use of Air-Flow devices for professional teeth cleaning, it is not yet possible to completely replace ultrasound. This is due to the fact that the Air-Flow device does not remove tartar, although it partly affects their “loosening”.

Important property mechanical whitening is relatively safe for tooth enamel, after all, the main effect is not on the enamel, but on the deposits located on its surface.

However, there are often cases when, after carrying out the appropriate procedure, rather unpleasant consequences can appear. Due to the fact that the removal of tartar and plaque is often carried out against the background of periodontal diseases (for example, periodontitis), after the procedure is completed, the cervical areas of the teeth are actually unprotected. Before this, stones saved them from all types of irritants, but after their removal, the necks of the teeth begin to react with pain to cold, hot, etc. (this is confirmed by numerous reviews on the Internet).

This problem This is most often resolved by a periodontist who treats the underlying disease and simultaneously carries out remineralization and deep fluoridation of hypersensitive enamel and (in some cases) root cement.

Below we will talk more about the use of so-called whitening toothpastes, the abrasive systems of which, if used ineptly, can cause considerable harm to teeth due to mechanical abrasion of the enamel.

When is teeth whitening really necessary and when is it unnecessary?

As practice shows, out of 10 people who turn to a dentist for a teeth whitening procedure, for only about 6-7 of them it will really be appropriate, and for the rest it will either be ineffective (since the enamel is already close to the natural shade) or extremely unsafe.

Cases in which whitening will be effective:

• Presence of plaque and dental deposits;
• Change in enamel shade due to age;
• Acquired staining of hard tooth tissues yellow or brown.

Difficult to bleach:

• Congenital enamel discoloration (for example, so-called tetracycline teeth);
• Gray coloring;
• Change in color of exposed dentin.

Staining due to plaque and tartar is eliminated by mechanical types of bleaching, and “internal” - by chemical ones.

Ultrasonic “teeth whitening”

Mechanical teeth whitening with ultrasound allows you to remove supra- and subgingival tartar from all surfaces of the teeth using ultrasonic devices and scalers. In addition, ultrasonic whitening allows you to clean the so-called “smoker’s plaque”, which is almost impossible to remove with either home or professional brushes.

Due to ultrasonic vibrations at the end of a special tip, mechanical destruction of the structure of dental plaque and stone occurs, as well as its “unsticking” from the surface of the enamel. If you follow the basic instructions for professional oral hygiene, ultrasound does not damage the enamel, and there are usually no negative consequences from this type of whitening.

By doing ultrasonic cleaning teeth, water is supplied to the tooth through the tip: this is necessary to ensure the safety and effectiveness of the procedure. Water helps prevent overheating of the tooth (this would lead to pulp necrosis), and also creates vortex flows due to the oscillatory movements of the tip, which improves the removal of tartar and plaque.

This is interesting

An ultrasonic toothbrush is quite suitable for home mechanical teeth whitening. The principle of its operation is approximately the same as in the case of the ultrasonic whitening method, but the possibilities are not as wide as in the dentist’s chair.

The power of ultrasonic vibrations in such brushes is reduced - adapted for safe home use. As a result, an ultrasonic toothbrush allows, albeit in a gentle manner, to remove plaque quite effectively. However, it should be kept in mind that such brushes are not recommended for people with a pacemaker or pregnant women. Their use is limited if there are braces, veneers, crowns in the oral cavity, as well as a large number of fillings (due to the possible risk of “dislocating” them due to ultrasonic vibrations).

Teeth whitening using Air-Flow technology

The essence of Air-Flow technology is the mechanical impact on an object (tooth surface) of a jet of air, water and ordinary baking soda released under high pressure. Thus, inside the Air-Flow apparatus there is sodium bicarbonate powder (regular baking soda, which in this case is used as an abrasive) and water-air channels.

Mixing water and soda occurs closer to the working part (tip) of the device. The device is fixed into the connector of the dental unit, and under high pressure, water mixed with powder is thrown onto the surface of the tooth enamel, cleaning it from even the densest plaque in seconds.

The convenience of teeth whitening using Air-Flow lies not only in the speed of treatment of one tooth, but also in the quality of such treatment. The jet released from the tip of the device easily penetrates even into tight spaces between teeth, cleans plaque under the gum, and effectively cleans teeth under structures, for example, under braces.

As a result, in about 30-40 minutes you can get teeth free of plaque and their natural color.

However, if you are planning to whiten your teeth using Air-Flow, you should remember that compared to ultrasound, this technology has reduced effectiveness against tartar. In addition, if you hold the tip of the device near one tooth for a long time (more than 3-4 seconds), it is possible not only to polish the enamel, but also to cause sensitivity after the procedure.

Additional mechanical methods of enamel lightening

Home methods of mechanical teeth whitening are perhaps the most popular among the population today, but at the same time they are not the most reliable and are even often dangerous for dental health.

Most often, in order to make teeth whiter, people try to use so-called whitening toothpastes. This is due to the fact that this idea is very attractive - you brush your teeth, and every day they become whiter and whiter...

At the same time, many do not even think that as a active component Most of these pastes contain abrasive powders, which actually actively remove plaque, but at the same time can also seriously damage the structure of the enamel (the enamel is simply gradually erased).

Uncontrolled long-term use of whitening pastes with a high abrasive effect almost always leads to increased tooth sensitivity and even the appearance of areas of damaged enamel in the form of depressions. Their localization is usually in the cervical region of the tooth.

This is interesting

The abrasiveness of toothpastes is characterized by a special index - RDA. For example, for ordinary toothpastes for daily use, this indicator can have the following values: about 20 for children, 45 for schoolchildren, 65 for adults with sensitive teeth. An RDA value of 75 - 150 is typical for whitening toothpastes with medium abrasiveness, and above 150 are already highly abrasive pastes.

On the toothpaste market you can find whitening toothpastes (for example, toothpastes from Thailand), in which this indicator is not indicated at all, and their composition includes almost ordinary clay. Even short-term use of such pastes can have a very detrimental effect on tooth enamel.

From analyzing research results on whitening toothpastes, and even just reading reviews ordinary people, we can conclude that whitening toothpastes based on abrasives can help cope well with soft and even hard plaque, but at the same time, over a certain period of time, they can also damage tooth enamel.

Whitening toothpastes based on chemicals (for example, enzymes) do not affect dense plaque with the force required by real whitening, which means that the results of their use are questionable. However, there are many defenders of this type of paste who note the whitening effect (but this does not take into account the fact that manufacturers often add abrasive substances to help a person cope with plaque using ordinary “friction”, and the presence of various exotics in the recipe In this case, the paste turns out to be nothing more than a marketing ploy).

Currently, there are many adherents of teeth whitening with a brush with hard bristles. The principle is as simple as that of a classic whitening toothpaste: to increase the efficiency of removing not only soft plaque from teeth, but also the so-called “smoker’s plaque.” As a result of long-term use of such a brush (even without whitening toothpaste), sometimes teeth actually become whiter, and also more sensitive to all types of irritants (cold, hot) and, in addition, more fragile.

Therefore, dentists often find zones of pathological abrasion (wedge-shaped defects) in such experimenters in the cervical area of ​​the teeth. It’s hard to imagine what will happen to such a tooth in a couple of months if you add a highly abrasive whitening toothpaste to a hard-bristled toothbrush...

Chemical bleaching with different systems: pros and cons

Chemical teeth whitening with existing popular systems can be divided into professional and home. Professional (otherwise known as in-office) whitening has a good whitening effect due to high concentrations of hydrogen peroxide or its derivatives, which are the active components of gels applied to the tooth surface.

Modern technologies chemical teeth whitening also involves the use of activators that initiate the breakdown of peroxides with the release of active oxygen. It can be:

• Warm;
• Ultraviolet radiation;
• Laser radiation;

etc. The use of activators enhances the whitening effect and also reduces the residence time of aggressive compounds in the oral cavity.

The most important advantage of in-office whitening (by any system) is the achievement of well-defined teeth whiteness in more than 70-80% of cases, and in just one visit. In certain situations, you can whiten your teeth not by half a tone or tone, but by 5-7 shades on the color scale.

The most important disadvantage of this type of whitening is the damage caused to the enamel, which, however, can be minimized by remineralization and fluoridation of the teeth after the procedure (but may also become one of the main causes of torment and suffering in the future). Violation protective properties enamel during chemical teeth whitening - this is on this moment one of the main problems that scientists are still trying to solve.

How does professional chemical teeth whitening differ from home whitening?

Firstly, the concentration of bleaching agent for professional types of bleaching is much higher (usually 30-35%). "Home" concentrations - no more than 10-15%. This is due to the fact that at the dentist’s appointment there are more options for protecting the gums and oral mucosa from aggressive substances.

Secondly, real results from professional whitening can be obtained much faster (usually in one visit), but home methods (for example, wearing trays) can take 2 or more weeks.

Thirdly, professional types of whitening often involve additional activation of a chemical reaction using laser-based devices, ultraviolet radiation etc. - to achieve the most pronounced, fast and safe effect.

Dentist-controlled home whitening methods are based on the following operating principle:

• special acid components etch the enamel in order to ensure its increased porosity and permeability;
• and hydrogen peroxide (or its derivative) discolors the colored compounds in the pores of the enamel, as a result of which lightening occurs.

To ensure the safety of this type of teeth whitening, dentists make individual trays for the patient based on impressions, so that during home procedures the gel was located directly on the teeth, reducing the risk of gum burns.

The most important plus is the reduced harm to the enamel (compared to in-office teeth whitening), and the minus is insignificant whitening rates, although such methods are quite suitable as a fixing procedure.

Professional and controlled home whitening cannot be carried out if there are carious teeth in the mouth, old and unusable fillings, plaque and tartar, as well as severe bleeding of the gums due to inflammation due to periodontitis. In such cases, it is advisable to first carry out sanitation (treatment) of carious lesions and replacement of fillings at a dentist-therapist, carry out professional oral hygiene with the removal of tartar and plaque, transfer periodontitis to a stage of stable remission at a specialist in diseases of the gums and oral mucosa - a dentist - periodontist, and only then think about teeth whitening.

Home methods of chemical whitening

In addition to controlled home teeth whitening using adapted whitening systems, there are also “amateur” options for carrying out such a procedure: whitening strips, pencils, trays, etc.

Whitening Pencil

A whitening pencil is a tube with a bleaching agent, and the shaft of the pencil itself, made in the form of a brush, brush or sponge, is used for application. The concentration of hydrogen peroxide in the composition is insignificant - 5-15%, but this is quite enough to cause chemical burns of the mucous membranes of the oral cavity if application safety precautions are violated.

Each person has individual characteristics of the structure of enamel and dentin, as a result of which it is impossible to accurately predict when exactly the undesirable consequences of the interaction of hydrogen peroxide with dental tissues in the form of increased sensitivity of teeth will appear (and whether they will appear at all). This can happen after 1-2 procedures, and in some cases - after 2 or more weeks.

The principle of using whitening pencils is simple - for this you should:

• rinse your mouth;
• wipe your teeth with a napkin;
• apply gel;
• sit with open mouth approximately 1-10 minutes (depending on the type of whitening pencil - the required time is indicated in the instructions for its use);
• then wash off the gel with water.

As a rule, the course duration is up to 2 weeks (2 times a day). Moreover, the result can be determined not only by the effectiveness of the drug used, but also by the person’s bad habits (for example, smoking, frequent consumption of strong coffee).

Whitening strips for teeth

The so-called whitening strips are polyethylene strips with a layer special staff, usually containing from 6 to 10% hydrogen peroxide. That is, as you already understand, this type of teeth whitening is also chemical.

The kit usually includes strips for the upper and lower teeth. The principle of home whitening strips is that they are pressed against the teeth for about 30 minutes - during this time, chemical reactions take place, leading to a gradual discoloration of the colored compounds present in the enamel.

The effect of whitening with strips may not occur at all: neither in 7 days, nor in 2 weeks, and sensitivity, according to numerous reviews on forums on the Internet, occurs in every third person. Moreover, it often manifests itself not even in pain from cold and hot, but in the form of a piercing ache in the tooth while holding a strip on it - but people still endure it.

Reviews of 3D Wite Crest teeth whitening:

“I’m a coffee and tea lover, so when I read reviews on the Internet about whitening miracle strips, like a fool, I rushed to buy them through an online store. I ended up buying a set of Crest Whitestrips 3D White. It clearly stated that they were perfect even for sensitive teeth, and my teeth weren’t particularly sensitive, so I thought they would definitely be suitable.

After I put these strips on my teeth for the first time and took them off, it seemed as if my smile had become a little whiter, and there was no pain at all. On the second day, I again applied them to my teeth according to the instructions for half an hour. When I removed the strip, I almost fainted: a piece of gum actually came off above my front tooth. Like the skin of a sausage, the skin wrinkled and peeled off in a thick layer.

When I ran to the dentist with this problem for clarification, she explained to me that this was a serious chemical burn gums, since the gel from the strip somehow managed to get under it. As the doctor explained to me, such cases with homemade whitening strips and pencils are not uncommon. Since the root of my tooth was exposed, she advised me to have gum surgery costing 8,000 rubles! And what do you think, people, is it worth risking your gums in order to later pay off such a sum?

Photo teeth whitening (ZOOM): advantages and disadvantages

Photo teeth whitening zoom is an in-office chemical whitening technology, but with the activation of the process by ultraviolet light. It is also called the ZOOM technique or “cold” teeth whitening.

In “cold” whitening, a hydrogen peroxide-based gel is applied to the surface of the teeth and activated by ultraviolet, halogen or LED lamp. The peroxide concentration is usually quite high, on average 25-35%.

Zoom photo whitening is one of the most effective methods, as its technology is specifically aimed at improving results and reducing tooth sensitivity (by reducing exposure time). Light radiation allows:

• increase the rate of decomposition of peroxide compounds with the release of active oxygen (which, in fact, plays a key role in the bleaching of colored substances);
• allows you to reduce the exposure time of the gel, which, in turn, reduces its negative impact on the enamel.

After the organic pigments contained in the enamel are broken down, it becomes noticeably whiter. However, in some cases, one procedure may not be enough.

After photo-whitening (ZOOM 4), which can last from 30 minutes to 1 hour, fluoridation of teeth is performed to prevent sensitivity.

Teeth whitening zoom

Despite the widespread belief that zoom photo whitening is one of the most gentle types of teeth whitening, we must not forget important point: largely because of the high aggressiveness of the compounds used, dentists try to minimize the exposure time of gels on the teeth in order to reduce side effects, and they are far from uncommon in dental practice.

The effect of zoom teeth whitening depends on the characteristics of the enamel and its original color for each individual person. You should not expect the same effect as in advertising: you are unlikely to dazzle all passers-by with a white smile; most often, teeth become 1-3 shades whiter, which is, in general, a good result.

After teeth whitening with zoom technology, you should limit the consumption of coloring foods and drinks (coffee, tea, wine, juices, chocolate, blueberries, blueberries, etc.), and in the first time after the procedure it is better not to consume them at all. This “white” diet after teeth whitening will allow you to maintain a white-toothed smile for as long as possible.

Sometimes the enamel becomes bleached in spots, which can be a very unpleasant moment that requires additional intervention. In addition, in addition to sensitivity from all types of irritants (up to severe pain) after the whitening procedure, it is often necessary to replace existing ones in the smile area, even good fillings, as they become visually yellower than whitened teeth.

Laser teeth whitening price (how much does it cost)

Laser teeth whitening is a modern and fairly effective method of teeth whitening, which has been practiced for about 15 years. Numerous studies have shown that in most clinical cases it is indeed effective and relatively safe.

The principle of laser whitening is almost the same as with the photo-whitening method: a whitening composition based on hydrogen peroxide is applied to the surface of the teeth, but the active substance is not activated ultraviolet lamps, but with a laser. A laser is a kind of catalyst that affects not only the speed of chemical reactions, but also their depth (completeness).

How is laser teeth whitening performed?

As with other types of professional teeth whitening, the dentist applies protective agents for the gums before the procedure to prevent burns to the mucous membranes, but errors in the work occur even in professional dentist. Even in numerous photographs of whitening (before and after), one can observe an interesting picture: before the procedure, the teeth were yellowish, but the gums pale pink, which is the norm. After whitening, the teeth became noticeably lighter, but hyperemia (redness) appeared along the edge of the gum, which indicates a marginal burn (which, however, usually disappears within one day).

Is laser whitening safe?

Practicing dentists often use this harmless complication in the form of a marginal gum burn to their advantage. Redness of the gums after the whitening procedure is usually not noticed by the patient, but against the background of very reddened gums, the whitening effect looks many times more effective (due to the contrast). The teeth could be lightened by only 1 tone, but the reddened gums will visually emphasize the effect, and the patient remains satisfied. After all, the most important thing is the first positive impression.

Laser whitening contraindications:

• Children under 18 years of age;
• During pregnancy and breastfeeding;
• If you are allergic to hydrogen peroxide and other components of bleaching systems;
• At diabetes mellitus and some diseases of the pancreas.

These contraindications are also typical for many other methods of teeth whitening. It must also be said that local contraindications for any professional whitening methods (except mechanical) are carious teeth, periodontal diseases in the acute stage, dental deposits (tartar, plaque), old and deteriorated fillings.

Stones and plaque will simply interfere with the chemical enamel whitening procedure, and are also the determining factor in the yellowness of teeth. Bad fillings can cause acute pain during the procedure, as hydrogen peroxide can penetrate microcracks in the filling deep into the tooth.

Periodontal diseases in the acute stage can worsen during the procedure, and it is difficult to isolate the inflamed gums. Increased bleeding of gums, among other things, worsens the quality of whitening.

Carious teeth during whitening is in itself a violation of aesthetics. Why give yourself a snow-white smile if it will show off 1-2 carious teeth with “blackness” or even with a carious cavity. In addition, when applying the gel to carious teeth, a sharp increase in pain is possible, up to an acute attack.

Is laser teeth whitening harmful?

It is not recommended to carry out bleaching in cases where it is impractical due to the natural light yellow color of the enamel. Typically, such teeth have a light yellow tint in the cervical area, white enamel in the middle and transparent closer to the cutting edge. Even if such teeth initially do not have increased sensitivity, then after whitening the maximum will be a half-tone lightening, but there will be big problems with treating dental hyperesthesia from various irritants (cold, hot, etc.) Often even warm water or food causes pain.

It is important to clearly understand that if teeth initially have increased sensitivity, then the whitening procedure can seriously aggravate the situation.

In-canal whitening

Intra-canal teeth whitening (in other words, endo-bleaching) is used if dead tooth acquires a dark shade due to its staining with substances formed during pulp necrosis, when pigments penetrate deep into the tissues dead tooth, or when it is stained with filling material.

In such cases, external influence on the tooth does not allow you to cope with the problem. But in-canal chemical bleaching allows you to solve this problem, as evidenced by numerous positive reviews.

Teeth whitening review which is better

“Since I was young, I always had white teeth, until I had a couple of caries treated between my front teeth by one, so to speak, “specialist.” Unfortunately, the doctor turned out to be a bigot, and I had to change the fillings, and in such a way that first the nerves were removed from the teeth, and then fillings were made. At first everything was fine, but after a year and a half I noticed that my front teeth began to change color to dirty yellow. This started to stress me out a lot, so I stopped smiling altogether.

After suffering for a couple of years, I began to look for a normal dentist. Some told me that crowns would help, others that laser whitening. A friend suggested a good doctor to me, who recommended intracanal bleaching, since this is where the problem with tooth color comes from. First, they removed my old filling, injected a bleaching agent inside, and put in a temporary filling. I came to the next visit satisfied: the tooth had become much whiter, and all that was left was to put a permanent filling...”

Oksana, Moscow

A bleaching agent based on carbamide peroxide, sodium perborate or hydrogen peroxide is usually applied inside the canal. The oxygen complex, in the process of a chemical reaction, discolors the colored compounds in the tooth tissues - thereby combating discoloration.

After endo-bleaching, the tooth acquires its natural color or becomes noticeably lighter. The success of intracanal whitening depends on the concentration of the whitening gel and the time it remains inside the tooth. The main thing here is to get to the dentist on time for a repeat appointment, since if there is a significant delay in time, the tooth may become too light.

Traditional methods of teeth whitening: harm or benefit?

Is it possible to whiten your teeth at home without using all these pencils, trays and whitening strips? Well, traditional methods Teeth whitening has been known for a long time, but their comparison with professional systems has shown questionable effectiveness and, most importantly, unsafety (in some cases).

Dentist-controlled home whitening systems are not considered traditional methods. Likewise, at-home whitening strips, trays, pencils, and similar products are scientifically developed systems for home use, which in comparison with “grandmother’s” methods are not entirely safe, but more or less close to evidence-based medicine and often show certain results.

Charcoal

From history we can recall that charcoal was the most effective method of teeth whitening in Rus'. However, at present, this whitening technology is hopelessly outdated (usually today they try to whiten teeth with activated carbon, which is sold in pharmacies in the form of tablets).

The idea of ​​using activated carbon for teeth whitening is based on its well-known ability to absorb various compounds from solutions (an excellent absorbent). For example, if you place an activated carbon tablet into an aqueous ink solution and stir, the solution will quickly become transparent.

However, with teeth everything is not so simple: it is foolish to hope that activated carbon will draw out the pigments that color it from the enamel. However, erase plaque (including stained plaque) activated carbon will be quite possible, although with the same success you can simply brush your teeth thoroughly with toothpaste with an average abrasiveness.

By the way...

The Splat line of toothpastes includes a toothpaste containing charcoal - “Splat Blackwood”. And this paste is not the classic white color, but intense black. What can you do if the consumer really wants...

Baking soda - does it whiten teeth?

Baking soda can significantly increase the pH of the environment in the oral cavity, neutralizing acids, but whitening teeth with it at home will be very problematic.

Baking soda powder mixed with water (or saliva) is a medium abrasive, so rubbing your teeth with it too intensely and frequently can easily lead to excessive abrasion of the enamel, which in turn will lead to increased tooth sensitivity (remember Air-Flow technology , which was described above). Naturally, soda does not discolor the colored compounds present in the enamel, and a small whitening effect can only be due to the removal of the colored plaque present on the teeth, which again will be safer to do with a properly selected toothpaste.

Strawberry

Oddly enough, the use of strawberries is one of the most popular among the “berry-fruit” methods of teeth whitening practiced among the people.

The suggested whitening recipe is something like this:

• You should take a strawberry;
• Cut it in half;
• Rub half of it over your teeth;
• Leave for about 10 minutes;
• Then brush your teeth with your usual toothpaste.

Let’s say right away that you obviously shouldn’t count on a pronounced whitening effect from using strawberries in this way. However, organic acids, which are also highly effective complexing agents, are ways to gradually “pull” calcium ions from the tartar matrix, thereby facilitating its loosening and subsequent abrasion with toothpaste.

However, with the same success, the long-term and regular action of organic acids will wash out calcium from healthy enamel - this can provoke the appearance of caries at the stage of a white spot in the smile area, the problems from which, without proper treatment, can be much greater than the benefits of such a dubious overall procedure.

It’s better to just eat strawberries and rinse your mouth - this will give you much more benefits.

Teeth whitening according to Neumyvakin

One more specific type Teeth whitening is the so-called Neumyvakin whitening.

The recipe is as follows: you need to add 20 drops of pharmaceutical 3% hydrogen peroxide to 0.5 teaspoon of soda, and then a couple of drops of lemon juice, then mix. The resulting paste is suggested to be rubbed with cotton wool not only on the teeth, but also on the gums inside and out.

It is believed that this paste not only whitens teeth by removing tartar and plaque, but also heals gums. There are many fans of this type of whitening, but does it have any effect?

When reacting with soda (sodium bicarbonate) and citric acid sodium citrate is formed, which has the properties of a complexing agent and is capable of firmly binding calcium ions, “extracting” them, for example, from tartar. Soda powder plays the role of a medium-strength abrasive, mechanically removing plaque (and partly tartar) from the enamel surface. Hydrogen peroxide has traditionally played the role of a chemical bleach, bleaching colored substances found in tartar, plaque and tooth enamel.

Thus, there seems to be common sense in teeth whitening according to Neumyvakin.

However, often this meaning quickly turns into “meaninglessness” if executed poorly in the hands of an ignorant person. For example, if the would-be experimenter has sensitive teeth, there are already wedge-shaped defects in the cervical area, but the slight yellow tint of the enamel forces him to frantically rub his teeth with Neumyvakin’s paste - in this case, the result will be very disastrous.

It’s another matter when a person has naturally healthy enamel, but the teeth are yellow (or even brown in places) from plaque and tartar - in this case, whitening according to Neumyvakin would be much more appropriate than in the situation described above.

By the way...

Toothpastes containing in their formulation pyrophosphates (complexing agents), carbamide peroxide and a medium-strength abrasive system (RDA in the range of 75-150) will, in fact, be a more advanced version of the paste prepared according to Neumyvakin.

We hope the information above will help you make the right decision regarding teeth whitening. If you already have some practical experience in this matter, be sure to leave your review at the bottom of this page.

The safety of this method has been repeatedly tested and proven by numerous medical studies. Clinical trials confirmed that the pH level in the oral cavity remains neutral during the procedure.

The laser beam is not only not harmful to the enamel, but also increases its density by approximately 40%. Laser technology is absolutely safe for gums and for patients with increased tooth sensitivity.

Advantages and disadvantages of the procedure

Although laser whitening is expensive, it is dignity are obvious:

• First of all, whitening strengthens the enamel.
• Laser technology does not damage or dry out enamel, does not harm teeth and preserves them chemical composition. Numerous medical studies confirm the absolute safety of this procedure for tooth enamel and pulp.
• This procedure does not take much time.
• After the operation there is no increase in tooth sensitivity.
• The operation makes it possible to obtain a lighter color of enamel compared to its natural color.
• One of the main differences laser technology from other methods is its therapeutic effect.
• The procedure is performed without anesthesia.
• Laser radiation is known to have bactericidal properties. Therefore, laser teeth whitening is also the prevention of caries. However, a short-term absence of bacteria in the oral cavity does not guarantee freedom from cavities in the future.
• The aesthetic effect of one such procedure lasts for several years (up to 10 years), provided that the patient does not abuse coloring drinks and products.

Flaws:

• the main disadvantage of this procedure is its cost
• There may be a slight tingling sensation during the laser whitening process.

Indications and contraindications

The indication for laser whitening is darkening of tooth enamel, and the list of contraindications is much longer:

• age up to 18 years (very thin enamel);
• During pregnancy and breastfeeding;
• gum disease in the acute stage;
• hypersensitivity, allergic reactions or the presence of individual intolerance to the components of the whitening gel;
• the presence of extended teeth in the oral cavity and a large number of filled teeth;
• period of orthodontic treatment;
• pathological or age-related tooth wear;
• poorly installed fillings, microcracks in teeth, porous enamel.

It is important to remember that before whitening you should cure your gums and teeth, perform professional teeth cleaning: remove tartar and remove plaque, treat and polish the interdental spaces, apply a special fluoride-containing preparation that strengthens tooth enamel. Only after such vocational training The procedure will give you a truly beautiful and snow-white smile.

Dental care

To maintain the results for a long time, it is very important to adhere to the rules of oral care:

• thorough oral hygiene, including flossing;
• dentists recommend using soft or medium hardness toothbrush, preferably with natural bristles;
• to give up smoking;
• periodic execution professional teeth cleaning;
• mandatory visits to the dentist once every six months;
• In the first days after the procedure, you must completely avoid coloring products (coffee, black tea, wine, etc.).

To prevent re-staining of the enamel, you should continue to follow these recommendations, and then your impeccable snow-white smile will delight you and those around you for a long time.

There is a misconception that laser technique and the Zoom technique are one and the same. In reality, this is not the case, although the laser and Zoom teeth whitening techniques are similar.

What to choose: Zoom or laser?

These most effective methods are based on the same principle: the enamel is exposed to a special gel that contains hydrogen peroxide. With laser whitening, the gel is activated by a laser beam, with Zoom technology - with the light of a special lamp.

What is better, laser whitening or Zoom, will have to be decided by the patient himself, since these methods differ significantly in price.

According to experts, the laser has a more gentle effect on the enamel, without causing any discomfort. In addition, the laser strengthens, heals and protects the enamel.

In any case, before performing the procedure, it is necessary to check the condition of the oral cavity and consult a dentist.

First, let's be clear: Is there a difference between teeth whitening and teeth cleaning?

Of course, this is not the same thing! When professionally removing plaque using Air Flow or ultrasound, tooth enamel is cleansed of coloring pigments. The tooth acquires its natural, natural color. Accordingly, teeth whitening air flow and ultrasound does not exist!

But during the whitening procedure, the color of the teeth becomes lighter than the original natural version. In other words, when brushing, teeth return to the original color with which they erupted, and when bleaching, they become lighter than the color they naturally have.

Ways to whiten teeth

What methods of teeth whitening are better and cheaper?

You can whiten your teeth in Moscow in different ways, but they are all divided into 2 groups:

1. Professional teeth whitening types and prices

This term means whitening under the supervision of a dentist, either in a clinic (office or office) or at home, but always after professional consultation and prescription of whitening drugs by a doctor. The price of tooth whitening depends on what methods and methods of dental whitening are used.

In a dental clinic, laser, chemical bleaching, endo-bleaching, photo-bleaching are performed, and home bleaching is carried out using an individual tray and gel.

1. Independent (non-professional).

To do this, patients buy whitening pastes, special pencils and strips, freely sold in pharmacies. In this option, all actions are carried out according to the average instructions of the manufacturer of bleaching products.

Self-bleaching often leads to complications and increased sensitivity of teeth, because patients do not take into account contraindications to such manipulations.

And the mythical quick self-express teeth whitening in one hour, as such, is not lightening the tooth surface. Some so-called “whitening pens and teeth whitening strips” paint your teeth white and last only a few hours.

Effective teeth whitening

Truly effective teeth whitening in dentistry depends on factors such as:

1. Original color

White-yellowish teeth whiten best, white-brownish teeth are a little worse, and white-grayish teeth are even worse. Tetracycline and fluorose teeth whiten poorly or practically not.

1. Way

The best option is professional laser bleaching, photo bleaching is less reliable, and chemical bleaching is even less active.

At home, the most active systems are those containing urea and hydrogen peroxide.

1. The presence of composite fillings, ceramic veneers and crowns in the oral cavity

During whitening procedures, all fillings, veneers and crowns do not change their color, so their presence must be taken into account before the procedure begins.

Teeth whitening before and after photos

Teeth whitening gel

Dental whitening gel is the central element of any professional whitening system. The process of changing the color of dentin and enamel is ensured thanks to a whitening dental gel, which contains concentrated hydrogen peroxide and urea. Often, such dental whitening gels contain the mineral components calcium, phosphorus, and fluoride to saturate tooth enamel and dentin. Some gels contain desensitizers to prevent sensitivity after professional whitening.

The composition of professional gels is very different from those intended for independent use. As a rule, non-professional gels are less active, which requires more time and sessions to obtain an acceptable result.

Teeth whitening procedures

All professional whitening procedures have their own clinical protocol, compliance with which ensures a minimum of possible complications and maximum efficiency.

So, here is the sequence of actions:

1. First, they carry out diagnostics, find out the reasons for the color change, take an x-ray, assess the condition of the gums, identify caries, and evaluate the condition of composite fillings and other dental structures.
2. The dentist selects a suitable whitening system
3. Professional removal of dental plaque is carried out
4. The gums are isolated
5. Concentrated whitening gel is applied to the teeth
6. The gel is activated by a laser or a special lamp
7. Gel is removed from teeth
8. Teeth are coated with protective varnish

If restorative bleaching is done at home, then individual trays are made, into which the patient applies the gel and places it on the teeth. Depending on the procedure, this is done once or twice a day for two to three weeks.

Recently, amazing white in-office and at-home express whitening has become very popular among consumers, patient reviews confirm this. In some cases it is carried out even in shopping centers. This method complements such well-known brands of dental whitening systems as global white teeth whitening gel, opalescence treswhite supreme, teeth whitener white light.

Before and after teeth whitening procedure

Before the procedure begins, the patient is warned about the possibility of not fully achieving the planned results, especially if he has fluorosis or white-gray teeth. This may require repeated sessions. Also, if you have old fillings and crowns on your teeth, they may need to be replaced if the whitened teeth turn out to be lighter than them. The answer to the question: “How to whiten an old, darkened filling?” is to replace the dark filling with a light one.

For three hours after the procedure, you should not eat food that stains, drink wine, black coffee, and you must refrain from smoking cigarettes and hookah.

Complications after teeth whitening

In terms of severity, complications after bleaching can lead to:

1. Chemical pulpitis, due to burn of the pulp by gel
2. Hypersensitivity
3. Burn of the gums during the procedure

All these negative processes are caused by a concentrated solution of hydrogen peroxide and urea included in the whitening gel. Therefore, before starting the procedure, it is necessary to consult a dentist and take into account contraindications. Most often, patients complain that their teeth hurt after whitening.

How long does cosmetic teeth whitening last?

The period of preservation of the whiteness effect on teeth depends on many factors and on average ranges from six to twenty months.

Below is a list of actions that prolong the life of teeth whitening:

1. Using dentist-recommended toothpastes
2. Regular (every four months) removal of dental plaque in a dental clinic
3. Avoiding coloring foods, strong black coffee, smoking cigarettes, cigars and hookahs
4. Polishing and coating with protective varnish every four months

What are the contraindications to teeth whitening?

In order to accurately determine what contraindications exist for you personally or for another specific patient, you need to get a detailed consultation with a dentist.

Below is a list of general contraindications:

1. Untreated carious cavities
2. Systemic general allergy of the body
3. Oncological diseases
4. AIDS, syphilis, hepatitis C
5. Systemic collagenoses (Bechterew's disease)
6. Lactation and pregnancy
7. Cracks and chips of enamel
8. Exposing the necks of the teeth
9. Gum diseases

Pros and cons of teeth whitening

Whitening refers to the aesthetic section of dentistry. Changing the color does not improve the functional quality of the dentition and is not a vital dental procedure. That is why the patient needs to weigh and evaluate everything, because the complications of this procedure and the subsequent costs of maintaining the achieved result must always be taken into account.

Let's evaluate the advantages:

1. Get results quickly
2. Minimally invasive technology (compared to veneers)
3. Relatively affordable prices

Now let's compare the disadvantages:

1. Tooth sensitivity about 1-2 weeks after the procedure
2. Post-procedure care requirements
3. Need to quit habits (smoking)
4. Restrictions on the consumption of coloring foods and drinks (coffee, blueberries, red wine, etc.)

However, if after weighing everything, your choice is in favor of whitening, we strongly recommend that you consult a dentist to choose the best whitening option.

3. From the cost of consumables.

High-quality teeth whitening, the price of which is significantly lower than the average, is only possible with a promotion, with a discount in dentistry in Moscow or other cities of Russia.

One of the most common reasons why patients visit the dentist is poor dental aesthetics. Genetic abnormalities and disorders acquired during life lead to changes in the color of the enamel. The surface of the teeth acquires a yellowish, brown or dirty gray tint. You can quickly and effectively lighten tooth enamel using laser teeth whitening. This is one of the most popular and effective techniques in aesthetic dentistry.

The procedure does not require special preparation and is one of the safest and most simple ways to give crystal white teeth. Laser whitening services are provided in specialized dental clinics. Its cost is quite high, it has its pros and cons. After reading our article, you will learn many interesting facts about laser whitening.

What determines the effectiveness of the procedure?

To understand how different whitening agents work, you need to find out what causes teeth to turn yellow. Enamel changes color due to one or more reasons, including:

• deficiency of microelements and vitamins in the body;
• bad habits;
• change hormonal levels;
• consumption of coloring foods;
• bad ecology.

Under the influence of these factors, the enamel is destroyed, and dentin begins to appear through the resulting holes. This substance stains the surface of the teeth in an unpleasant shade. Therefore, darkening of the enamel not only worsens appearance, but in itself is dangerous to health.

The action of a laser beam is based on a chemical reaction. Before using it, a special solution is applied to the surface of the teeth, the components of which interact with dentin. As a result of this reaction, the pigment is destroyed, and the teeth acquire a pleasant snow-white shade.

Laser whitening also actively releases oxygen atoms. As a result, the process of pigment destruction is accelerated. The patient does not feel pain either during or after the procedure. Anesthesia is not used, because There are no nerve endings in the teeth, and the gums are covered with a protective film during the session.

Dentists recommend not limiting yourself to one procedure. How many sessions you need will depend on the initial condition of your teeth. The price of the entire course is determined by the number of procedures. Therefore, turning to laser tooth enamel lightening in time is not only healthy, but also financially beneficial.

Advantages of laser exposure

Patients respond mostly positively to the laser teeth whitening method. Positive reviews of the procedure were received due to its undoubted advantages.

1. Instant results. Even after one session, the enamel is noticeably brightened.
2. Efficiency. The procedure lasts no more than an hour. If you don’t count the time, you can limit yourself to 40 minutes.
3. Painless. Laser exposure does not cause even the slightest discomfort in patients with low threshold pain sensitivity.
4. Safety. Is laser teeth whitening harmful? Whitening tooth enamel with a laser is not at all harmful. After the session it is not disturbed acid balance, so tooth sensitivity does not change.
5. Strengthening teeth. After the procedure, the enamel becomes stronger and more durable. This is evidenced not only personal feelings patients, but also research by doctors confirming the densification of the tooth surface up to 40%.

Today, laser teeth whitening techniques are one of the most gentle and safe. This technology does not require special preparation of the oral cavity and is prescribed for many indications related to aesthetic problems of the dentition.

Disadvantages of laser procedures

The disadvantages of laser whitening are traditionally associated with financial factors and contraindications. How much does laser teeth whitening cost? The price of one session in some clinics reaches 8-10 thousand rubles. A full course can cost about 25-30 thousand rubles. At your preliminary consultation, your doctor will tell you how many sessions you need.

Another disadvantage is associated with the presence of contraindications for laser teeth whitening. The procedure is prohibited under the following conditions:

• gum disease;
• inflammatory processes in the oral cavity;
• children's and adolescence;
• a large number of fillings, the color of which cannot be corrected;
• pregnancy and lactation;
• presence of braces;
• individual intolerance to components;
• tumors of various etiologies.

Under no circumstances should these conditions be neglected. Otherwise, bleaching will not only not help, but will also be harmful to your health and beauty. Many patients are interested in whether laser teeth whitening causes side effects. Unfortunately, it is possible for negative reactions to occur after the procedure.

1. If the enamel layer was thin to begin with, the laser can destroy it and damage healthy tooth components. In this case, after the procedure, sensitivity will increase and painful sensations.
2. Laser whitening may not work. It copes well with stains from coffee and tea, but is powerless against the action of tetracycline.

Due to the fact that light irradiation can be useless and even harmful, and the price of laser teeth whitening is high, it is necessary to consult a dentist before the procedure. It is important to choose the right clinic, because teeth whitening is a medical method. Therefore, be sure to read the photos and reviews of patients who have previously trusted a particular doctor.

Dental care after the procedure

To keep your teeth white, follow all your dentist's recommendations. Only in this case the enamel will remain crystal clear for a long period after the procedure. As a rule, aftercare comes down to a number of rules.

1. Do not neglect daily hygiene procedures. However, it is prohibited to use products containing any abrasive.
2. For a week after the session, you will have to stop eating foods with coloring properties: wine, juices, beets, carrots, etc.
3. Do not smoke for at least 3 days after the whitening procedure. Otherwise, your teeth will acquire a yellow tint, which will be extremely difficult to remove.
4. Visit your dentist regularly. At the end of the course, you will be scheduled for at least one more appearance to evaluate the effects of laser treatment.

By following these simple rules, you can provide yourself with a real Hollywood smile without any complications. If it is difficult for you to give up your usual lifestyle for a short period of time in order to consolidate the effect, look at a few photos with the results before and after teeth whitening. Shots like these are highly motivating to action.

No matter how many alternative methods of enamel whitening appear, the laser will always be appreciated. A pronounced effect with a minimum of disadvantages ensures this procedure is consistently highly popular. For those who are soon planning to undergo laser cleaning, it will be useful to watch the final video. The video shows how whitening is carried out in professional clinics.
