Over 30 million Americans use dentures to replace their missing teeth. Denture users also use denture cream to prevent food from becoming lodged between the gums, dentures, and the roof of the mouth.
Popular brands such as Fixodent and Poligrip can cause severe health issues many denture cream users may not be aware of. Fixodent and Poligrip both contain zinc. If too much zinc is ingested, then zinc poisoning may occur, leading to copper deficiency and neuropathy.
Super Poligrip, manufactured by GlaxoSmithKline (GSK) and Fixodent, made by Procter & Gamble (P&G), use zinc in their adhesives to help attach the dentures to a person’s gums. The instructions are misleading and vague on how to use the denture creams. Individuals will sometimes apply more cream than needed, potentially putting them at an increased risk for developing copper deficiency and neuropathy.
