Literature Review: Evaluation of Dentin Hypersensitivity After Tooth Bleaching Procedures

Abstract

Tooth bleaching procedures have been largely used. Techniques and products were improved along the years. However, some problems are still present and must be surpassed. Dentin hypersensitivity after tooth bleaching affects over fifty percent of pacients, in different levels. The present study aimed to review
the current literature on the methods available to prevent and reduce the incidence and the intensity of hypersensitivity, using clinical protocols before,
during and after the bleaching procedure. Among them, we highlight the choice of the technique and gel concentration, use of desensitizing agents and fluoride application, and administration of analgesics and anti-inflammatory.
