Q. I resently had an extraction lower back tooth, and after a couple of days it got infected. I when back to the dentist and they said it was a local infection and put what looked like a ball of tabaco in my extraction hole. I returned 2 days later for some different treatment and they looked at the infected tooth again and said its healing and the thing they put in will work its way out after a bit. I’ve had it in a total of 4 days now and am worried that it won’t come out what if it heals over it ?? please help i’ve even considered removing it my self!!,
