ABSTRACT
This chapter focuses on the power bleaching technique used to achieve more immediate results on multiple vital teeth, with special consideration given to treatment of the single vital tooth and when combined techniques may be employed. Improvement in bleaching products in the mid-1990s including photosensitive formulas, and delivery systems such as light-cured barrier materials, increased use of in-office bleaching for multiple vital teeth. During the treatment planning process, observing the character and depth of discoloration can help discriminate whether the patient is a suitable candidate for in-office power bleaching. Teeth that may not be suitable for in-office power bleaching include those with moderate to severe intrinsic discoloration. A single vital tooth that has a calcified or reduced pulp chamber may not respond well to in-office bleaching. As part of the initial patient interview, the advantages and disadvantages of in-office professional bleaching should be discussed relative to at-home bleaching and expected outcomes.
