Vital tooth bleaching in dental practice: 1. Professional bleaching

As dental health improves, with the concurrent drop in the provision of basic restorative care, patients are now asking their dentists to provide aesthetic treatments rather than the treatment of disease. Tooth bleaching is one such treatment that is frequently described in consumer magazines and television shows, driving consumer interest in this, apparently, benign therapy. This three-part series demonstrates the techniques that can be employed, within the dental practice or under the supervision of a clinician, those systems that can be bought by patients over the counter and, finally, a discussion of the biological effects of peroxide-containing solutions and the legal position on such products in the UK. In this section, we will describe the common methods by which teeth can be bleached, either by the clinician directly, or under his/her supervision by the use of'at home' kits. Efficacy and safety issues will be described.

Clinicians should be able to discuss the merits, risks and likely success of a variety of bleaching treatments with their patients and, in doing so, assist in the process of obtaining informed consent.
