Will I be needing more procedures for a healthy smile? I've asked before about my crowns but I wasn't able to upload pictures and such. I found out I'm allergic to the metal that was used in the crowns I had done in 2008 as a child. Just yesterday both of my crowns on my 8 and 9 fell off. And when they did the most disgusting odor of rotten flesh hit me. I have a gummy smile decaying teeth, pain and gum swelling, went to the Dr today said I need crown lengthing, new crowns and possibly crowns on my 7 and ten. Any advice? For more info let me know.
