A week ago today I had an extraction done on my #30 molar. I had a root channel done on it around 20 years ago but needed to be pulled due to infection. The procedure itself was horrendous. I can only remember one other thing in my life that was more painful. He pulled it out in pieces. I will never be awake for anything like that again. Anyway everything seems to be healing fine except for one spot that feels like a cut. Could this be a tooth fragment? It's hard, sharp and wiggles. The gum is also a little red and sore around the location.
