question: About 4 months ago I had a filling done in my tooth. It was very sensitive for weeks and I even went back although the dentist said it looked fine when he saw it. Eventually the sensitivity went away. Then about 3 weeks ago my gum next to the filled tooth started shedding.. like if I'd burnt the inside of my mouth. I assumed it must have been something I ate, but now three weeks later it is an open space that I can actually feel my tooth through. There is no pain, but because of the holidays I haven't been able to get into the dentist. Will be trying to get in tomorrow, but I'm hoping someone here can give me an idea of what I'm looking at...
