I had a 2nd molar out almost three weeks ago which was badly infected. I also had the wisdom tooth next to it taken out. The dentist seemed bothered about the molar at the time as he kept going back to look at it before I left but he didn't say anything. It came out with an abscess attached to it apparently. It is still completely open almost three weeks later and doesn't seem any more healed than the day it came out. It's slightly tender sometimes but not really painful. The wisdom tooth site has healed.
I went for a check-up today and mentioned it and he asked how it felt on my tongue, it just feels like a big hole! He said there were tricks he could do if it didn't heal up soon but that it really should have closed by now. Does anyone know what these 'tricks' are. I didn't ask at the time..I have no idea why not.
