Denture Adhesives And Nerve Damage

Lawsuits have been filed beginning in 2006 claiming permanent nerve damage from using denture adhesives. A recent article in the Journal of Neurology studied 4 patients, all who used two tubes of adhesive a week and all developed neuropathy exhibited as limb weakness and poor balance. Denture adhesives contain zinc. Zinc is an essential naturally occurring element present in chicken, beef and present in many vitamins. Six medium oysters have about 77 mg of zinc. It is needed for growth, development of bones, metabolism and wound healing. Recommended daily amounts for adults is 8 to 11 mg a day. The maximum dose should not be higher than 40mg a day. Toxicity occurs after prolonged exposure at about 100 to 150mg a day. At this level it lowers copper levels in the body which adversely affects the spinal cord. A small 2.4 ounce tube of Polygrip contains 2,754 mg (2.75g) of zinc. It is supposed to last 6 weeks using a small amount once a day (see photo). If all of it is absorbed or ingested you would receive 66 mg a day. The individuals who suffered neurotoxicity used one or two tubes a week and they potentially could have received as much as 197 to 393 mg a day. If you have been using denture adhesive and are experiencing nausea, vomiting, fatigue, muscle coordination or balance problems your zinc levels should be tested. The best advice is to avoid zinc containing adhesives and use zinc free. Don’t wear your dentures while sleeping especially filled with adhesive. Also if you have to use a lot of adhesive under your denture it is time to see the dentist for a reline or new one. An implant secured dentures will eliminate the need for denture adhesive altogether.
