It has two porcelain crowns with visible metal backs (inside the mouth) on the anchor teeth and two fake teeth in between where my two teeth are missing. He called this a wide span bridge, with porcelain over metal. I asked what metal and he reported the palladium, and I thought, great. I'm getting a metal taste coming from the back anchor tooth which has the amalgum in it which is very disconcerting. I will definately have to keep going till I find someone willing to do something for me. I am not really into "putting up with it" as he suggested (the metal taste).
