Today GSK alerted consumers to a potential health risk from long-term excessive use of zinc-containing denture adhesives Super Poligrip 'Original', 'Ultra Fresh' and 'Extra Care'.
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 and blood problems such as anemia. Neurological symptoms may include numbness, tingling or weakness in the arms and legs and difficulties with walking and balance.
Super Poligrip is safe to use as directed in the product label. The majority of consumers follow these directions. However, some consumers apply more adhesive than directed and use it more than once per 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. GSK has discussed this situation with the FDA and no further action is required.
What consumers should do
If you have been using zinc-containing Super Poligrip 'Original', 'Ultra Fresh' or 'Extra Care' for several years in greater amounts than directed on the package or more than once per day, or have concerns about your health, you must:
1. Stop using the product.
2. Talk to your doctor.
3. Use a zinc-free alternative such as Super Poligrip 'Free,' Super Poligrip 'Comfort Seal Strips', or Super Poligrip 'Powder'.
People with ill-fitting dentures should seek help from their dental care professional, rather than compensate for poorly fitting dentures by using excessive adhesive.
Polident Denture Cleanser tablets contain no zinc and are not affected by this announcement.
GSK will soon be introducing zinc-free versions of Super Poligrip 'Original', 'Ultra Fresh' and 'Extra Care'. Zinc Free Formula will be clearly shown on the new packaging.

I hate to sound like a broken record, but the other commenters are correct. Very few things are good in excess. Denture adhesive is no exception. Use some common sense, like everything in life, and you can usually avoid situation like this. Discount Dental Plans.
I've read other studies that connect excessive zinc intake with multiple sclerosis as well, specifically with denture adhesive products. I agree with Dermot above, people should go by the rule "Less is More". -Dora, Golden Rule Dental
Less is more when it comes to denture adhesives. People should start by using less adhesive and then working their way up, and make sure the glue is spread evenly. And those who haven't visited their dentists in a long time should go for a checkup, even if it means getting a new set of dentures made, as new ones are definitely better than using old ones with glue.
