Typically, highly concentrated preparations based on hydrogen peroxide are used for professional teeth whitening. The active substance penetrates into the dental tissues and discolors the pigment. However, a side effect of this procedure is increased sensitivity of the teeth. Therefore, after it, it is necessary to carry out fluoridation or remineralization.
Sodium perborate is used for cosmetic teeth whitening. This is a crystalline form of hydrogen peroxide that does not penetrate deep into the dental tissue. The substance acts only on the surface of the enamel, delicately restoring the natural shade to the teeth.
Cosmetic teeth whitening – features of the procedure
During cosmetic teeth whitening, the active ingredient is activated by the cold light of an LED lamp. A chemical reaction occurs, as a result of which oxygen is released, which dissolves the pigment.
The light of the LED lamp does not have ultraviolet radiation in its spectrum, so overheating of dental tissues, sunburn in the lips and burns of the mucous membranes of the oral cavity are completely excluded. But the eyes still need protection, so the patient wears special glasses.
How cosmetic teeth whitening works
Cosmetic teeth whitening procedure consists of several stages:
Tooth cleaning from soft plaque to facilitate access to active ingredients.
Applying a brightening gel to the enamel and lighting it with an LED lamp.
Removal of gel residue after a few minutes.
After the session, two hours you can not drink and eat.
