Sorry to hear about your experience with the dentist Ole.

The dentist I used to replace 10 fillings over 3 years ago managed to miss a very small piece of amalgam under one tooth, which I had removed earlier this year. He seemed like a good dentist at the time, the only one I could find that was available in my town following a safe protocol, but as protected as he had me (dam, suction, oxygen, etc...) my dentist was breathing in the vapors as he drilled them out...his mouth was only covered by a thin face mask that dentists normally wear. I could tell the poor guy was having symptoms at the end of each of my 3 sessions, he would seem really uneasy and definitely seemed to be reacting to the vapor of my removal. I wasn't sure what to do, but I figured I was paying him properly and it was his choice to be exposed.
