I couldn't get the pre root canal x ray from my old dentist. I talked to one dentist who saw the x rays with white spot and he said yes it could be rc material but that wouldn't cause a problem, and if there is no apparent sign of infection, to let the nature heal the extraction. I just saw my OS ( the jerk, because I couldn't get appointment with somebody else for 3 weeks ) when I asked about that white spot, he said yes, that's rc material, but that's not a problem at all. He said to either open it up, or wait a couple of weeks more. I'm afraid I will wait and end up having it open up anyway, but I'm afraid to have that re opening done. It's still a little red inside the socket, he took a panoramic x ray, he doesn't see anything on it, but said the x rays doesn't pick up everything.
