"Did you get this done after you got your fillings replaced"

It has a root canal and a metal post. I doubt it has any mercury in it. It was very deeply excavated. There wasn't much left of the tooth, so I at least glad that I didn't need an extraction and an implant. I know having the metal in my mouth is not good, but still better than the alternatives. At least I made sure the other crowns don't have a metal lining or metal post.
