My dentist says I don't have any Amalgam in my root canals because root canals that turned into apicoectomys are typically done with amalgam. Not regular root canals. I am trying to figure out whether he is right. He said that root canals are not and have not been filled with amalgam. He looked at my xrays and said I do not have any root canals that have apicoectomys. Can I believe him?
