Professional teeth whitening is divided into two types — office, that is, in the dentist's chair, and home. If we draw bleach correctly, it is necessary to take both of these steps. There are two types of office bleaching: in the first case the reaction starts by mixing the two chemicals in the second — is triggered by the action of special lamps or lasers.

Office bleaching. In procedures commonly used office bleaching solutions of 30% hydrogen peroxide or carbamide without warming and etched enamel surface. These procedures are performed in the dental chair using cofferdams (the rubber gasket to isolate the work area) to protect the soft tissues of the oral cavity. Bleaching agents are applied to the exposed surface of the tooth is about 20 minutes to start whitening sharp. Then we recommend home whitening agents assigned to the dentist.

In addition to the jump-start can be used funds, which contain activated light components together with a concentrated solution of hydrogen peroxide.

Home bleaching. Since the end of 1980 it had become a popular home whitening. Pets bleaching agents contain as active ingredient carbamide peroxide which reacts with moisture oral allocates atomic oxygen provides removal stained spots, i.e. bleaching effect. Tools include home whitening 10-22% Carbamide peroxide and assigned to a dentist who follows the dynamics of the process of bleaching. Duration bleaching may be from 2 to 4 weeks, and the maximum effect is observed at the end of the third week.

Applitsiruetsya means using splints (mouth guard), the type of boxing, which is worn for up to two hours a day. Bleaching with splints (mouth guard) has the same indications and results, as well as the usual office bleach, but it can be done for less money and with fewer side effects, such as burns tissue and increased tooth sensitivity.

The combination of office and home bleaching. Many manufacturers of whitening dental products currently offer a combination of both home and office whitening system as a way to maximize the whitening effect. A combination of both systems allows the patient to get the best whitening effect.

Laser whitening. Laser whitening is becoming increasingly popular among dentists. This system allows you to effectively bleach teeth in a relatively short period of time. However, it is worth mentioning a few points related to the use of lasers. First, laser is not whiten teeth, but merely accelerates oxidative effect of hydrogen peroxide. Secondly, oral cavity must be carefully prepared to the procedure as high concentrations of hydrogen peroxide. Third, no data in the literature that laser whitening whiten teeth better home or office bleaching.

Retail bleach. Consumers should be cautious to use acid-containing bleaching agents that are sold in retail stores. These bleaching systems are usually described as a process consisting of three steps: preliminary 15-second acid washing, coating1-2 minutes acidic gel with hydrogen peroxide to the front surface of the teeth with Q-shaped tip and applying white pigment.

Temporary whitening effect in this case may arise due to the superposition of white pigment on a lightly etched and enamel surface roughening. However, this process is harmful to the tooth structure, as acid can corrode the surface of the enamel.
