Besides having a dentist remove your amalgam SAFELY, do it over a period of time, not all at once. I had quite a bit of old amalgam fillings, around half a dozen or so. Some had to be replaced with crowns, I've stretch this out over a year. It was my dentist that suggested this. Even with all the precautions, he wanted to limit my exposure to the released mercury over time.
I'm not sure if removing all the amalgam in my mouth helped any. My pd back then was still progressing even after all the amalgam was removed. I just wanted that mercury out, I figured it couldn't hurt. I can't remember where I've read about mercury fillings & pd. but it was enough to convince me to spend a couple of thousand to get it out.

Happy drilling.
