Lawsuits for Neuropathy, Zinc Poisoning and Other Health Problems from Poligrip Denture Cream

GlaxoSmithKline’s Super Poligrip could leave users with serious and potentially disabling injuries as a result of high levels of zinc contained in the denture adhesive cream for several years. Although Glaxo discontinued all versions of Super Poligrip with zinc in early 2010, they were aware of the health risks for years before that and failed to adequately warn users about the potential risk of zinc poisoning.

The Super Poligrip lawyers at Saiontz & Kirk, P.A. are reviewing potential denture cream lawsuits throughout the United States for individuals who have suffered symptoms that may be caused by zinc poisoning, such as:

  • Numbness
  • Tingling or Pain (Pins and Needles Sensation)
  • Muscle Weakness
  • Unexplained Pain
  • Loss of Balance
  • Difficulty Walking
  • Loss of Sensation
  • Paralysis

Potential PoliGrip lawsuits are being pursued against GlaxoSmithKline for failing to warn about the possibility of high levels of zinc entering the body and for failing to properly instruct users about the safe use of their product.

At the time zinc was added as an ingredient in Poli-Grip, it was known and accepted within the medical community that excess zinc in the body could cause significant problems, including copper depletion or hypocupremia, which may result in neurological damage that is often irreversible.

Studies estimate that denture wearers who use Super Polygrip or other similar denture cream products may be exposed to 330 mg of zinc daily, while the recommended daily allowance is only 8mg for women and 11 mg for men. The National Academy of Science has indicated that the largest tolerable zinc intake is 40 mg.

GlaxoSmithKline was aware that large amounts of zinc could be absorbed by the body from their products, yet they did nothing to warn consumers or make sure that they were not overusing the product.

Unfortunately, as another consequence of GlaxoSmithKline’s failure to disclose the potential Super Poligrip zinc poisoning side effects, many doctors were unaware of the potential connection between zinc poisoning and denture cream products. Therefore, the symptoms may be misdiagnosed as other conditions, preventing proper treatment and resulting in the users continuing to use the Poli-Grip denture cream product.

A delay in stopping use of Poligrip can result in permanent neurological damage. Although zinc levels may be reduced once the product is no longer used, many consumers are left with the pain and neuropathy caused by the zinc poisoning for the rest of their lives.


Potential Super Poligrip lawsuits are pending throughout the United States on behalf individuals who have been diagnosed with elevated zinc levels or depleted copper in the blood that may have been caused by use of the denture cream. Using large amounts or using the product over a long period of time, may increase the risk of a user suffering Super Poli-Grip zinc poisoning.
