It should be noted that teeth whitening is not in itself necessary for medical reasons. This, however, does not make this procedure useless for the patient: modern whitening gives a very noticeable effect – tooth lightening up to 10-12 tones, which greatly affects the appearance of thepatient, and therefore on his/here success, personal life, etc.
It should also be noted that the teeth may become lighter (though not to the same extent) even after a comprehensive cleaning, air flow procedure or removal of dental tartar.
Absolute contraindication to the whitening is an allergy to hydrogen peroxide.
Whitening often leads to increased sensitivity of the teeth (usually for 1-2 days after the procedure).
