Remember that a lot of dentist are mercury poisoned, too. Assistants, too. I have a dear friend whose husband was a dentist and then he became an oral surgeon. He was our neighbor and we went to the same church. He poo pooed my mercury issues, though, (and said my hives..reactions to chemicals in the "ice smog" in AK was nerves...mercury can cause FMS which is a syndrome, basically, but causes chemical sensitivity which mercury can too itself without FMS I imagine) and even gave his own wife and kid amalgam fillings! What a dough head! I lost respect for him at that point. His wife later, though, said she felt the poison after she got the fillings. She also use to work as an assistant and felt sick when she did. Now that I think of it, she doesn't talk to me anymore. Her husband likely discourages it. She was like a little sister and listened to me. For a while.... I wasn't trying to nor would I want to come between them over that, but thank goodness he got out of dentistry. They are more affected than anyone...
