A study done by Amar Patel, DDS, and his colleagues at the University of Maryland Dental school claim that zinc, which is an ingredient in many dental products, may be hazardous. The study appears in the March/April issue of the journal of General Dentistry.
Zinc is good for the body when the body is exposed to it in small doses, however, too much is potentially toxic. Some patients could have neurological problems from zinc exposure, and others could experience nausea, a stomachache or mouth irritation.
