A firend of mine is a dental assistant, they all wear uniforms at the dentist. Before they could wear their uniforms out and about when they left the dentist on their lunch hours or when they went home. Now however, they are not allowed to wear their uniforms outwith the dentists. I asked my friend why this was and I said I bet its to do with the mercury, she said "well yes among other things" They may be improving things like not wearing their uniforms out and about so as to stop spreading toxins etc, but why still then put it in peoples mouths, isn't that mad !!!!
