I have a badly broken upper 2nd molar which I think was filled also. I have about half of the tooth still above the gumline but on the broken portion some of the break is slightly below the gumline. There is absolutely no pain involved so obviously no exposed nerves or root problems. I have been advised the only solution is extraction, which I am reluctant to have unless there is absolutely no alternative. Is it possible to save the tooth by just filling (sealing) the area without necessarily building up the crown in the normal manner. ?
