According to an article in the Los Angeles Times on December 21, zinc can be found in supplements, cold medicines, denture creams and fortified foods. And although zinc deficiency can create problems of its own, zinc poisoning can cause memory loss, nerve damage, copper deficiency and other neurological issues.
Among those most likely to suffer from zinc poisoning are people who use excessive amounts of denture cream. One tube of denture cream is meant to last a month, but people with loose-fitting dentures often use one to two tubes of denture cream a week. Add to that the zinc they may be taking in from other sources, and denture cream users could have astronomical amounts of zinc going through their system.

Some denture cream makers have taken steps to warn consumers about the risk of using their product in excess or while taking a zinc supplement. However, consumers say the warning comes too late—they should have been warned sooner about the risks associated with denture cream overuse.
At least one lawsuit has been filed against the makers of certain dentures. The plaintiff argues that her denture cream caused her neuropathy, and that she would not have used the denture cream if she had known about the risks.
