Efficacy, risks of over-the-counter tooth-bleaching agents

Investigators have evaluated the effectiveness and adverse effects of over-the-counter tooth-bleaching products.

In a study published in the Journal of Dentistry, the investigators used the PubMed/MEDLINE, Embase and Scopus databases to identify 88 in vitro, in situ and clinical studies focused on the effects of over-the-counter tooth-bleaching products. Among the products included in the study were whitening or stain-removing toothpastes and whitening strips.

The investigators found that the efficacy of whitening strips was supported in clinical studies, whereas the efficacy of whitening toothpastes, mouth rinses and whitening trays was supported in in vitro studies. The most common adverse effects reported in the studies were tooth sensitivity, gingival irritation and enamel surface changes.

The investigators concluded that clinicians should familiarize themselves with the risks of over-the-counter tooth-bleaching products and communicate these risks to their patients.
