Fears about overuse of denture adhesive

Long-term use of a popular brand of denture adhesive could cause high levels of zinc in the body linked with neurological problems such as numbness and difficulty walking, a pharmaceutical giant has warned.

GlaxoSmithKline (GSK) has stopped the manufacture of adhesives which contain zinc. It said customers who have used more Poligrip Ultra and Poligrip Total Care than directed on the packaging over a number of years should stop using the products and get medical advice.
