I went to the dentist about 6 weeks ago as I had tooth ache in my top left molar. My dentist put a filling in my tooth and for about two weeks this stopped the pain. Then my tooth began hurting agin when I ate and drank so I went back. My dentist told me the filling might be too high so he ground it down. Then last week the same pain came back when I was eating and drinking cold drinks. Does anybody please have any idea what the problems could be?? Thanks...
