Whether tooth whitening is safe or not is a question that has
been asked by doctors and patients for some time. Perhaps one of the more
common questions is whether or not tooth whitening can be linked to oral
cancer.
An article published by the ADA in 2010 regarding the safety of
professional tooth whitening states that "information collected over the
last 20 years including some long-term clinical study follow-up indicate no
significant, long-term oral or systemic health risks associated with
professional at-home tooth bleaching materials containing 10% carbamide
peroxide (3.5% hydrogen peroxide)."1 It has specifically been
observed that low concentrations of peroxide do not cause cancer,2
but may cause temporary gingival irritation or sensitivity. In addition, no
further studies have been performed to show that higher concentrations of peroxide
cause any health risks or that they may be linked to oral cancers.
Based on the information provided in studies regarding the use
of tooth whitening products and the risk of oral cancer, it has been concluded
that tooth whitening products are safe and effective, making it possible for
everyone to obtain a bright, white smile without risking their long-term
health.3
