A crown made of Diamondcrown and gold here is about $600. Yes, Dentists do not like to answer questions normally. Some, it is an ego problem, some just don't want to be bothered, and some do not have a clue as to the answers of your questions, and sometimes a combination of those. I have bridges in my mouth (most are temporary and need replaced, haven't done it yet) and diamondcrown fillings. I don't know what kind of bridge, it was biogold, I think; It was done according to my biocompatibility chart, so I'm sure it is fine. Click here for the chelation I did. I did everything but the cilantro and chlorophyll, just never got to it, but I did eat lots of cilantro at the time.
