Hi sheetu, I read the Amalgam Forum for a long long time before I picked Dr Morales to take out my mercury fillings. After reading about so many people having bad experiences with regular dentists, I knew better than to do that. My fillings were replaced with diamondlite material and two years later they're still doing fine.

Basically it's where you've had wisdom teeth removed by a regular dentist and they didn't remove the peridontal ligaments. I'm a believer for sure!
