Q. Hello. I had an old PFM crown on my peg lateral removed because it had a dark line showing at the gum and has caused an amalgam tattoo. I currently have a temporary crown while waiting for my permanent. My dentist removed some of the gum (contouring?) because it sat much lower than the surrounding teeth. To me, it looks like she removed too much. She said she did that on purpose because the gum comes down after the procedure. It has been two weeks and it is still high. I believe she made a mistake. I asked another dentist on this site and he said it is true that the gum generally comes down. How can that be? I am nervous because my amalgam goes up so high under my gum that I don’t want my new crown to either look too high or show the amalgam. I went 20 years with a bad crown and was looking forward to a nice new one.,
