Hi doctor,
I had a dislodged filling from my tooth at the beginning of the year, but it did not hurt. When I went to the dentist, they said the tooth was infected and I would need a root canal treatment and a crown placement. This is the second time the filling fell out from the same tooth. Both fillings came out within six months of the procedure. However, I am allergic to metals like silver, etc., but I need to get a crown placement. My insurance revealed that porcelain ceramic (which they cover) does not contain metal. However, my dentist informed me that it has metal, and I need to upgrade to zirconia, which costs extra money. Can you confirm whether there is metal in a porcelain ceramic crown?
Please reply.
