I have a crown that I believe is a Porcelain-fused-to-metal crown. The
metal is some kind of of non-gold alloy used by most dentists. My
dentist recently replaced the post that holds this crown and put in a
golden post.

Question: I heard that the fact that the post if made of gold and the
crown is done using some other metal can be a problem due to the
charges and ions that can occur.

I am thinking of replacing my crown and putting in a crown that is
porcelain based on gold, not just a metal alloy. Does it make sense? I
don't have any problems with this crown right - no pain or other
problems. Should I replace it?

Thanks.
