Users of denture creams may suffer from zinc poisoning, according to an article published on WFFA.com. Fixodent manufacturer, Procter & Gamble, may be responsible for placing high-risk products on the market. After four years of denial, GlaxoSmithKline has admitted that the use of Super Poligrip could lead to zinc poisoning, which also causes neuropathy (disturbances of the nervous system) in denture wearers. Although zinc is no longer an ingredient in Poligrip, Procter & Gamble continues to sell Fixodent with zinc and claims that the product is safe to use as directed.
Common symptoms of zinc poisoning, or hyperzincemia, that may be caused by Fixodent include tingling, diarrhea, cramping, vomiting, headaches and other flu-like symptoms. If left undiagnosed and untreated, Fixodent side effects are far more serious.
One death has already been reported due to over-exposure to the zinc in the product. It is estimated that 35 million Americans use denture cream every day. At the time this article was written, Procter & Gamble maintained that Fixodent was safe and will not stop its manufacture.
