Hello,

Recently I decided to remove all mercury fillings from my mouth. After consulting my primary care dentist, I was told that I only had one filling, but that he was unsure whether the tooth with a gold crown was filled with amalgam, since it was filled by another dentist. I contacted the other dentist and was told it was filled with a composite and there was no amalgam involved.

Here's my question. The tooth prior to the root canal and eventual crowning was filled with an mercury amalgam. What are the chances there is any mercury left over after the crowing? Does the crowing and root canal process involve taking out prior fillings due to the use of filing or other methods? I REALLY do not want to remove this crown, it costed me a small fortune and would hate to do it in vain.

Thank you for any insight?
