The teeth whitening procedure involves a chemical reaction that removes various discolorations from the teeth and makes the teeth whiter. Discoloration is a change in tooth color that can occur from coffee, wine, long-term consumption of cigarettes, as well as some foods.
The chemical reaction of oxidation of the outer surface of the tooth is achieved with the help of two substances, urea peroxide and hydrogen peroxide. Teeth whitening can be done in the dental clinic and at home (night teeth whitening).
Whitening at the dental clinic involves the application of whitening gel to the teeth, using high- concentration whitening in strictly controlled conditions by the dentist. When bleaching, special attention is paid to the protection of soft tissues, and the activation of the gel is done with the help of a lamp or laser beams. This procedure is short-lived and in one visit to the dentist, the desired shade of tooth color is achieved.
Night whitening involves making an individual foil for teeth, which will serve as carriers of whitening gel. The dentist marks the side of the foil into which a small amount of bleach is applied and the foil is applied over your teeth. The procedure is simple, safe and uses gels to whiten lower concentrations that cannot damage soft tissues if applied properly. Teeth whitening with this method is slower compared to dental clinic whitening and you follow the results from week to week.
