A review of the safety of tooth bleaching.
This article considers the safety of tooth bleaching based on a Medline search of clinical, animal and in vitro studies between 1986 and 2007.


CONCLUSIONS
Bleaching is the least invasive option for improving tooth colour compared to alternatives such as crowns and veneers. However, no dental procedure is without risk and the clinician should be aware of the safety issues and adverse effects of tooth bleaching so that patients can be fully informed.
