Today, in a fashion completely white teeth, despite the fact that dentists believe that any whitening hurt enamel - it becomes thinner and prone to fracture. However, bleaching is carried out, and certainly better if it will conduct a professional, you have a dentist. There are several ways of professional teeth whitening.

What is a professional teeth whitening and its ways

Professional teeth whitening - bleaching is dentist's office. Teeth whitening is carried out at the request of the patient, as well as before, or prosthetics before sealing the tooth, so as to whiten your teeth after these procedures would be impossible: Proceedings of the seals and the prosthesis does not bleach.

Teeth Whitening has a number of contraindications, which must take into account the dentist. It caries, periodontal tissue damage, including gums, enamel cracks, poorly executed seals, sensitive teeth, wearing orthodontic appliances (eg, bracket systems), pregnancy, breast-feeding, allergic to hydrogen peroxide.

Any dentist whitening begins with dental treatment. Treated caries, set the seal, if necessary, we treat the gums. Once the teeth are treated, the dentist holds a professional teeth cleaning, which resulted in the teeth a few shades lighter. But it does not bleach, but simply the removal of plaque and stain removal from the coloring food substances. Brushing your teeth can be done by a dentist tools, special sandblasting or ultrasonic devices. After brushing their need to grind and polish to prevent deposition of bacteria on their surface, and only then proceed to the professional teeth whitening.

Any bleach - this change is the natural color of teeth with chemicals. Carried out such bleaching can with special whitening systems and catalysts (accelerators of chemical reactions). Catalysts can be chemicals, lasers or irradiation by light. In accordance with this professional teeth whitening is carried out in three main ways: chemical, laser and with the help of light (fotootbelivanie).

Chemical bleaching of teeth

Chemical teeth whitening done by a high concentration of bleaching gel and a catalyst that can speed up the bleaching process. Gels typically contain carbamide peroxide, hydrogen peroxide, chloride in high concentration, so the effect will be noticeable after the first session lasting about 30 minutes. Whitening effect usually lasts long enough.

High concentration bleaching gels for professional teeth whitening are slightly acidic reaction medium and in contact with hard tissues of tooth decay slowly with the formation of atomic oxygen, so they almost always cause a violation of the enamel and the emergence of increased sensitivity of the tooth. Nevertheless, competent dentist may well apply such bleaching systems without much damage to the teeth.

In some cases, tooth whitening is not necessary to hold the outside and inside. For example, an injury a tooth can be painted in pink, which will eventually become brownish and will be significantly different from the color of other teeth. Change in tooth staining can occur in the process of treatment and root canal fillings (tooth becomes darker). Such teeth whitened is not on the outside and inside. To this end, the cavity is placed whitening gel and imposed a temporary filling. After a few days filling in the tooth is exposed and placed a new portion of the gel, because sometimes it is necessary to make up to five times until the tooth is equalized by the color of the surrounding teeth. Only after this is established permanent seal, corresponding to the color of the tooth.
