It's the whole filling that was dropped in pieces (four to be exact) into the gum area and dental bone while doing gum surgery years ago. So I would assume a combination of silver and mercury.
Honestly, I think there's more concern with mercury/silver in skin and bone tissue than in the tooth itself.
I appreciate everyone's response, but will try Newport's suggestion.
I want them out and believe it's keeping me from getting my health back.
Thanks about the reminder about Vit C, I had forgot that it affects numbing and I want it numb ;)
