On my left side of my mouth above my second molar there is a bump about the size of a pea that is very sensitive to pressure. When I press on the bump if feels as if I m trying to pull out my molar. Any idea what this bump could be. About 5 years ago I had a filling done on this tooth. There is no pain coming from the tooth though. Only pain from the pressure of the bump. It s getting to the point now that when I m eating occasionally it will bother me.
The bump in that region suggests that you are having an infection below that filling that you got five years back which is spreading to the roots and forming pus there. Usually this can arise when the decay spreads below the filling, and we call it secondary caries. Though it's not bothering you much now I would suggest you to get an x-ray of that region that would clarify it, and then you would require a re-filling with a root canal treatment. Don't be deceived by the painless nature of it as it may grow any time and get it treated as soon as possible. Take care.
