English Summary

Tooth bleaching requires a proper diagnosis, and must be regarded as an alternative to dental procedures like laminates and full crown therapy. It is not recommended perform cosmetic adjustment of the tooth color to solely to comply with the demand of the patient. Tooth bleaching can be performed in the dental office or at home, supervised by the dentist (night guard bleaching). Both external (vital tooth bleaching) and internal bleaching of the teeth have good efficacy and long lasting effects if carried out on selected cases. High frequencies of tooth sensitivity and gingival irritation are reported in clinical studies evaluating tooth bleaching. Risk assessment reveals that night guard bleaching causes the patient to be exposed to doses of bleaching agent close to the estimated safety margins, especially when excessive biting on the tray is performed.
