This is a dental question. Does anyone know of the toxic concerns with the
materials used in removable dentures? I know there are metals used in the
cheaper ones and some kind of synthetic used in the more expensive ones.
Or where can I get this information. Certainly not from a mainstream dentist.

Dentures This is a term that describes an appliance that replaces teeth. It can be a full denture, or a partial denture. Full dentures (commonly called "plates") replace all the teeth and are held in by the attraction formed between tissues and plastic due to the saliva in between. Full dentures are constructed of plastic with either porcelain or plastic teeth. The plastic is colored pink to assimilate the color of gums. The pigments that are used to form the pink color are usually mercury sulfate, cadmium sulfate, or a combination of both.
"Immediate dentures" are placed immediately after the teeth are removed and are a type of splint to hold the tissues in place while healing takes place. They need to be "relined" in a few months, for shrinkage of bone and tissue takes place daily and the fit is worse each day. Relining is adding new plastic on the tissue side of the denture so that an improved fit can be established.
"Partial dentures" are dentures that replace several, but not all of the teeth in either the upper or lower arch. They generally contain plastic that hold the teeth and the plastic is processed onto a metal framework that has little arms called clasps that hold onto the remaining teeth. There is a bit more stress on the remaining teeth, but it is offset by the added chewing surface area provided by the additional teeth.
Metals in the partial dentures can be gold (now really rare), nickel, beryllium, cobalt and chromium with a few other metals at levels of one percent or so.
