Zinc-based Denture Creams Linked to Neurological Damage

Did you know that many denture creams contain zinc? 

While zinc is an important essential trace element, in excess it can cause numbness, gait disturbances, tingling in hands, metallic taste in the mouth, low blood pressure, yellow eyes and skin, nausea and vomiting.

A study published in 2008 in the journal Neurology found that excessive use of denure creams containing zinc could result in serious neurologic disease

These symptoms occur because denture adhesive users swallow small amounts of zinc during the course of a day (this is especially true for people who use large amounts of adhesive). When zinc levels reach 40mg a day or higher, zinc begins to displace copper (another essential trace element), and central nervous systems dysfunction occurs.

Zinc also interacts with medications some antibiotics (such as Cipro and tetracycline).

Zinc can reduce the absorption and action of penicillamine, a drug used to treat rheumatoid arthritis. And zinc can also interfere with diuretics such as chlorthalidone (Hygroton).

Manufacturers are not required to list zinc or zinc toxicity on product lables. So it is up to health care providers, family members and concerned individuals who wear dentures to pay attention to unexplained neurologic symptoms or abnormal blood test levels or zinc or copper.

Some zinc-free denture adhesives include:

*Secure Denture Bonding Cream
*Secure Denture Adhesive Cushion Strips
*Sea-Bond Denture Adhesive Wafers
