Wow! Its amazing that some of us can be that sensitive to mercury vapors. And Im glad you wrote about it because I am a dental hygienist and work 2 days a week. I have to polish when Im done with the scaling. It just goes to show you that you are reactive to the vapors however mild it seems. Good luck with getting the fillings out. Make sure you get oxygen, a rubber dam and high volume suction and try not to swallow anything. Best of luck, Diane Tilson p.s. Makes me wonder about continuing my career as a Dental hygienist. HMMMMM
