Although tooth bleaching has been known to the dental profession for over 100 years, new knowledge is continually surfacing. This review discusses the 1990 to 1991 literature on two nonvital bleaching techniques (thermocatalytic and walking) and three classes of vital bleaching techniques (in-office; dentist-prescribed, home-applied; and over-the-counter kits). The choice for nonvital bleaching is the walking bleach technique, with the use of sodium perborate alone having less potential for cervical resorption. The choices for vital bleaching techniques are either the dentist-prescribed, home-applied technique, the in-office technique, or a combination of the two. Bonding should be delayed 2 weeks after bleaching. Microabrasion is a possible second choice for certain discolorations. These chosen bleaching techniques, when used in a professionally appropriate manner, seem as safe as other commonly used dental treatments.
