dentures To date, the FDA has not issued any advisory to the public or the profession on this issue.

Nearly 35 million people in the United States wear dentures and many of the widely used denture adhesives previously contained zinc. If a denture wearer used large amounts of the adhesive, and swallowed it, there are claims that a person could receive too much zinc, potentially resulting in a lowering of copper and possible serious neurological issues.

Since 2009 lawsuits have been filed claiming inadequate warning labels on Poligrip and Fixodent alerting wearers to potential effects of too much zinc consumption. There is a recent resurgence in television advertising for such lawsuits and it is important to note that zinc containing denture adhesives have been pulled by major manufacturer, GlaxoSmithKline. Zinc-free is now clearly shown on packaging.

Denture wearers are advised to see their dentist if their dentures do not fit well or if they have questions about the use of dental cream. Dental examinations and appropriate care can reduce the need for denture adhesive products. Regular dental checkups are important for everyone, including denture wearers.
