A few years ago, I had a filling fall out of one of my molars. After a few months the lingual cusps broke off. And within the next year, the other cusps broke off. So now there is a kind of hole and the roots are still in there I assume. I'm sure there is some kind infection as I have drainage. There is no toothache but my gums seem somewhat inflamed but not really painful. My question is : what is the procedure that I will need and approximately how much does it cost? I live in fort Wayne Indiana and have no dental insurance.
