For the duration of the procedure, the gums and other oral mucosa are insulated by applying a special protective agent to them.

Whitening itself begins with the treatment of the patient's dentition with a special composition( gel).It includes a mixture of minerals, fluoride and hydrogen peroxide. The gel has the ability to penetrate deep into the tooth enamel and reach the dentin.

The procedure is performed by exposing the teeth of a diode laser strictly at right angles. Each tooth takes about 2-3 minutes to process.

In the process, oxygen atoms are released, which then penetrate into the dentin. There, the applied gel oxidizes and causes destruction of the pigments responsible for darkening the teeth.

Depending on the initial color, one such procedure may be sufficient for a patient, or several may be needed. The enamel brightens at 5-10 tones.

With proper and regular oral care, the whitening effect can persist for a year or even several years.

Reviews of patients dental clinics about teeth whitening can be studied below.

The result of photobleaching, of course, is impressive. Teeth became not like a star, but the difference is very noticeable, they really became white, not grayish.

The only negative that I was able to detect is an increase in the sensitivity of the teeth after the procedure and for a couple of months. Even the mouth in the street was difficult to open, and in the first days I had to take an anesthetic. But I've had a snow-white smile for a year now.

Nikolay, 31 year

The procedure was performed in three sets of 15 minutes. I did not feel any particular discomfort, only at first there was an unpleasant sensation in my teeth. Teeth really have become much lighter, but not dazzling.

For 2 weeks, I observed a colorless diet so that my teeth did not darken again. But six months have already passed, and my teeth begin to change color again. I expected a longer-term effect.

Snow-white smile with chemistry

Chemical teeth whitening is based on the use of special gels, but without the participation of any additional devices. The procedure is possible only in the absence of problems with the teeth and gums.

If there is caries or inflammation of the mucous membranes of the mouth, then the disease must be previously cured. Usually, before the chemical bleaching, a professional cleaning of the teeth from the stone is carried out.

The gels used for bleaching are based on carbamide peroxide or sodium perborate. They are considered to be the most effective and harmless. Both that, and other substance at penetration in a dentin causes oxidation of oxygen and clarification of a tooth enamel.

To perform chemical bleaching, the patient's lips are fixed using a special retractor device. Then the Chemical whitening before and after dentist treats the patient's gums with a protective compound. The teeth are applied with a whitening gel and remain on them for 15-20 minutes.

The procedure allows you to lighten the teeth by 2-3 tones. To many patients this is quite enough. The effect lasts for 6-12 months. It is recommended to carry out professional cleaning at such intervals.

The cost of the procedure is from 2500 to 5000 rubles.

The patient's opinion is below.

Ultrasonic cleaning was advised by my new dentist for medicinal purposes. But I can not help but note the whitening effect of the procedure. Teeth became much lighter, darkening of enamel went away.

In general, the smile has found a healthy, natural color. As for the procedure itself, it was a little uncomfortable when cleaning the front teeth, but tolerant. Now I will try to do this whitening at least once a year.

Constantine, 34 years old

I read a lot about the dangers of all sorts of tooth whitening, and ultrasound on the background of the others looked the most innocuous. What can I say? The teeth are certainly not white, but rather they have become a natural color. But the result is really tangible. In general, I'm quite happy. In addition, this procedure, in contrast to others, also provides a therapeutic effect.

So what to choose?

Determining which tooth whitening is best can only be relative, since it is possible to consider such procedures in terms of cost, efficiency or safety.

Regarding the achieved result, here, undoubtedly, the leading effect of photobleaching is. In addition, this procedure is considered one of the safest and takes a little time. At the cost it is quite affordable, but the prices for it are not the lowest.

The cheapest is chemical and ultrasonic whitening. But with their help you can achieve only a slight clarification of the enamel.

In this case, the use of ultrasound does not presuppose a chemical effect on the teeth, only their surface treatment occurs, which means that this method is also the most safe.

How Dangerous is Professional Teeth Cleaning?

The issue of the harm of professional bleaching causes a lot of controversy. Earlier it was believed that such procedures are very damaging to the teeth and have a destructive effect on them.

But modern formulations used in such procedures are as safe as possible and have in their composition not only bleaching agents, but also strengthening agents.

Nevertheless, some disadvantages of professional whitening still have:

  1. In the vast majority of cases after carrying out similar manipulations of , the teeth become very sensitive to and react sharply to hot and cold. Discomfort can arise even while talking on the street. But such unpleasant sensations usually pass in the first few days.
  2. Some concentrated gels can lead to the formation of cracks on the surface of the tooth enamel of , which with pulpitis will only grow.
  3. In addition, with insufficient protection of the gums, you can get an burn.
  4. If bleaching is performed with untreated caries, this can lead to the development of pulpitis.
  5. If the timing of exposure to special formulations, the lifetime of the photobleaching lamps is out of date, or the use of substandard gels, the result of the procedure may be depressing: from getting a chalky shade of the teeth to serious burns. Non-compliance with the rules for treating chewing elements with special gels and pastes can lead to their destruction.

The guarantee of a successful professional bleaching procedure is the search for a good clinic and a highly qualified dentist.

Only a specialist can assess the real state of the patient's teeth, objectively determine which type of bleaching is appropriate for him, and ensure the desired result.
