Glaxo Removing Zinc from Denture Creams: Part 2

Hi everyone,

I received this email blast from the Ontario Dental Association regarding the removal of zinc from denture adhesive pastes. Here's the quote:

GlaxoSmithKline (GSK) warns about a potential health risk associated with long-term, excessive use of zinc-containing denture adhesives Poli-Grip "Advanced Care," "Extra Strength" and "Ultra Fresh."

Media Releases from Glaxo Smith Kline:

GSK will stop manufacturing these zinc-containing denture adhesive and plans to replace them with zinc free products.

While zinc is an essential part of the diet, recent publications suggest that an excessive intake of zinc-containing denture adhesives over several years may lead to the development of neurological symptoms such as numbness, tingling or weakness in the arms and legs, difficulties with walking and balance, and blood problems such as anemia.

Poli-Grip is safe to use as directed in the product label. However, some consumers apply more adhesive than directed and use it more than once a day. Therefore, as a precautionary measure to minimize any potential risks to these consumers, GSK has voluntarily stopped the manufacture, distribution and advertising of these products.

Health Canada has not to date issued a recall of the product. These measures are being taken by GSK.

ODA Members may wish to advise patients who use denture adhesives to:

  • follow package instructions
  • use zinc-free alternative such as Poli-Grip "Original," "Comfort Strips" or "Powder" and
  • arrange a consultation with you to assess ill-fitting dentures.

Consumers with questions may call GSK at 1-888-521-8033.
