I have tooth 3, 4 and 5 covered by one long one piece crown. It's been there for about 30 years. It looks like 3 teeth but it's one piece. If one tooth has to be extracted, how do they do this? Do they remove the whole piece, drill it off? Then what would I have to do? Replace both crowns with new ones? Or do they file it and smooth it some kind of way? I am asking because #5 aches when I put my tongue on the outside of the tooth, moreso in the middle of the night than any other time. It will be OK for weeks, then it will happen again. Doesn't seem like an abscess and nothing shows on x-ray, may be sinuses but I am at the point where I just want it out. I am nervous about the long crown thing, how they do it. Any feedback would be great.
