The main aim of this randomized controlled clinical trial is to evaluate the efficacy of a bioactive glass desensitizer in reducing tooth sensitivity associated with in-office vital tooth bleaching. In addition, this study aims to compare the effectiveness of the bioactive glass desensitizer with that of a fluoride gel and a gel without desensitizing agent with regard to incidence, intensity, and duration of tooth sensitivity and, finally, to investigate how these agents affect tooth-shade following in-office bleaching. The hypothesis of the study is: There will be no difference in the effect of a bio-active glass desensitizer on tooth sensitivity associated with vital in-office tooth bleaching compared to a fluoride gel and the bio-active glass desensitizer has no effect on the bleaching efficacy.

Tooth sensitivity associated with vital in-office tooth bleaching
Timeframe: Assess sensitivity during the bleaching, 1 hour after bleaching, 1 day, 2 days, 7 days and 14 days after bleaching.
