"Hollywood smile" to date is an integral part of the image of a successful person.Professional teeth whitening: methods, contraindicationsIn connection with this fact, dentists are constantly looking for all new methods of bleaching. Professional teeth whitening, unlike home, is performed in the dentist's office using high concentration components and special devices.

The quality of the result achieved depends on the particular structure of the teeth of each patient, the level of qualification of the dentist who conducts the procedure, and compliance with the rules for oral care after the procedure.

Professional teeth whitening implies the selection in each case of bleaching agents and methods that are most suitable for a particular situation.

Note that there are contraindications to this manipulation! Not all teeth can succumb to the bleaching procedure, but the dentist can offer, as an alternative, an art restoration with the use of veneers (plates sticking on the teeth) and crowns.
Professional teeth whitening is possible only after special preparation. To do this, first heal the caries affected teeth, check the installed seals for strength, if necessary, install new ones, enamel is cleaned, polished, grinded and fluorinated.

After the bleaching procedure, you should not eat food that can color the enamel, and smoke.

Professional teeth whitening has, as already mentioned, a number of contraindications, which include diseases of the mouth or teeth, for example, cracks in the enamel, caries, stomatitis, periodontitis. This should include allergy to components that are part of bleaching, breastfeeding or pregnancy.

Professional teeth whitening, reviews of which speak about the effectiveness of this method, can be carried out in several ways.

Chemical whitening. For this type of bleaching, a high concentration of hydrogen peroxide is used. The result is noticeable almost immediately and lasts quite a long time. Often the result of such whitening can also become an increase in the sensitivity of the teeth.
Another method of bleaching is the use of air-abrasive systems. In this case, the enamel is cleaned mechanically (using an aqueous mixture of cleaning powder and compressed air). So the enamel is lightened by several tones.

Another method is ultrasonic whitening. The enamel is polished and purified using ultrasound and some preparations.

Laser and photobleaching of teeth means applying a special solution to the enamel, which brightens it under the influence of a laser or halogen light.

At very dark enamel the method of the mixed bleaching which includes complex bleaching in hospital and houses is applied.

Professional teeth whitening, the price of which differs and depends on the way it affects the enamel, can not always be effective. Unfortunately, there are such teeth that practically do not lend themselves to the effects, the purpose of which is bleaching of the enamel. As a rule, these include teeth that have defects in enamel, with increased transparency, exposed to resorcinol, formalin. Long-term regular exposure of coloring products (such as coffee, green tea) to tooth enamel, too, can cause a lack of results from the bleaching procedure. In any case, before the procedure it is better to contact an experienced specialist who will objectively assess the situation.
