Only professional stomatologic procedure with application of compounds of hydrogen peroxide or peroxide of a carbamide of high concentration gives the real bleaching of teeth. The modern bleaching systems allow to bleach enamel not on one shade, as at mechanical clarification, and on two - three and more (on a scale of Vit).

before restoration or replacement of seals , and also before prosthetics as restoration materials and crowns are not bleached. It is necessary to start restoration only in two weeks after bleaching when the content of residual amount of hydrogen peroxide or peroxide of a carbamide in tissues of teeth is completely neutralized.
Before bleaching of teeth is necessary:
to carry out the general diagnostics of an oral cavity and to be convinced that soft fabrics (gums) are healthy;
to eliminate caries;
to carry out professional toothbrushing (to remove a soft dental plaque and scales);
to determine a shade of teeth by a scale of Vit.
Contraindications to bleaching are:
inflammation of a parodont;
an allergy or sensitivity to peroxide of hydrogen or a carbamide;
unsatisfactory hygienic condition of an oral cavity;
age - to children till 17 years bleaching of teeth is not recommended at all.
Relative contraindication is smoking (insignificant yellowness of teeth can return soon and the effect of bleaching will be gradually brought to naught).

Bleaching of teeth happens office and house.
At office bleaching teeth stomatologists usually use the systems containing 35% or 38% of hydrogen peroxide. The mechanism of bleaching of teeth is that pigmentation of tooth fabrics collapses active atomic oxygen which is formed at intensive disintegration of hydrogen peroxide (for acceleration of process of disintegration blue light of a usual photopolymeric lamp is used). In order that the bleaching substance did not get on soft fabrics of an oral cavity, special light-cured protective pitch which easily is removed after bleaching procedure is applied on a gum. Then the bleaching gel by means of the syringe is applied on teeth and remains on them within 15 minutes.
During procedure the dentist controls a condition of the patient and color of the bleached teeth. In the absence of problems and unpleasant feelings bleaching of teeth continues. After the end of procedure of bleaching (from one to three times for 15 minutes) on the bleached teeth if necessary puts on a cap with the gel reducing hypersensibility of teeth.
After procedure of office bleaching of teeth patients need to refrain within a day from the use of the food containing dyes : strong tea, coffee, beet, tomato, red wine, grapes.
House bleaching teeth by means of special mouthpieces has not such fast effect as office, but the patient can carry out procedures independently at home. What for this purpose is necessary? At first stomatologists do prints from teeth of the top and lower jaw. Then in laboratory, on the basis of these prints, cast models and make special individual a kappa for bleaching of teeth of silicone material on the lower and top jaws. To them the patient receives the special set containing syringes with active gel of low concentration (5 - 10% of peroxide of a carbamide), gel for decrease in sensitivity of teeth and the special toothpaste supporting effect of bleaching.
Dentists, proceeding from specific features of an organism of the patient will help to pick up the necessary bleaching gel and its concentration. Also they will make all necessary recommendations about use of gel for house bleaching of teeth, will show how it is correct to fill with deepening gel in caps how to enter a kappa into an oral cavity and to remove surplus of gel from a gum. A kappa with the bleaching gel put on for the night as it remains active within 8 - 10 hours. At emergence of sensitivity of teeth it is recommended to use gel for its decrease. All process of bleaching of teeth occupies on average one - two weeks. During procedure of house bleaching of teeth, and also within several days after it, it is necessary to refrain from the use of the “painting“ food.
After all types of bleaching of teeth (both office, and house) it is necessary to use constantly the special toothpaste supporting effect of bleaching and at least once in three months to carry out professional toothbrushing at the stomatologist.
Side effects when bleaching teeth
Bleaching injures teeth, causing education bigger, in comparison with unbleached teeth, numbers of external grooves on a tooth enamel surface. These grooves increase sensitivity of teeth to mechanical loading.
Active atomic oxygen destroys and brings out of tissues of tooth not only pigmentation, but also mineral salts of calcium, fluorine and phosphorus that leads to demineralization of solid tissues of tooth and further to formation of caries. Therefore carrying out the restoring remineralizatsionny therapy and deep fluoration of teeth fluorine preparations in certain cases is necessary.
After bleaching of teeth almost at all patients observes hypersensibility of teeth to temperature and chemical irritants which lasts during from one to three days and passes independently. Otherwise patients should take the anesthetizing medicine and to use special toothpastes for sensitive teeth.
the Bleaching gel can get under a sheeting of gums that leads to irritation of a gum and emergence of a burning sensation.
If bleaching of teeth is carried out at not cured caries or badly recorded crown, then the bleaching gel can get in tooth and cause damage sosudisto - a nervous bunch and, as a result, a sharp pulpitis.
