The increasing use of teeth-whitening products may be implicated in oral cancers among young adults. Bruce Davidson, MD, FACS, raised the question of a possible association between these products and cancer at the 6th International Conference on Head & Neck Cancer in August 2004. Davidson, who is chairman of otolaryngology-head and neck surgery at Georgetown University Hospital, reported on two patients who developed advanced tongue cancer "decades earlier than usual."

Ninety percent of oral cancers appear in people over 45 years of age, usually as a result of long-term smoking or excessive drinking. Neither of these two patients had more than three alcoholic drinks a week. One was a light smoker and the other didn't smoke cigarettes at all. Both used teeth-whitening products.

Teeth-whitening gels contain carbamide peroxide, a compound that contains urea and hydrogen peroxide. Free radical intermediates that form as hydrogen peroxide breaks down into water and oxygen are believed to react with the pigments that create tooth stains.

Over-the-counter teeth-whitening gels have a gradual effect and often require several weeks of regular use to have an effect. These gels may be brushed directly onto the teeth, or applied via an adhesive plastic strip or mouth-guard-like tray. In the process, free radicals may also come in contact with surrounding tissue, damaging cells. Even when dentists use custom-fitted trays to apply the gel, 50% or more of it can leak out of the trays, according to studies. Ingesting peroxide has increased the incidence of cancerous tumors inside the cheeks of rodents and caused gastrointestinal cancers.

Studies documenting a similar link in humans have not been performed. Davidson sees his observations as a call for further testing of teeth-whitening products and as a warning to consumers that a link between these products and oral cancer may exist.
