I too would like to hear people's experiences with this subject. I have been reading about dental issues lately. I had my Amalgams out a number of years ago, but I may still have some residual mercury, don't know. I also had 4 wisdom teeth out probably twenty years ago, and from what I read about chronic infections that can develop when the ligament is left intact attached to the bone, I'm now wondering about that! I don't think infection under a healed-over extraction would show up on regular dental X-rays - how in the world would you find out about something like that?
