I was having a root canal done yesterday when the tooth being worked on suddenly snapped off at the gum line. Fortunately the office has an oral surgeon on staff so the remainder of the tooth could be extracted immediately. It just popped right out after only 5 minutes of prying. Then the oral surgeon had to fill the hole with a bone graft. So now my mouth hurts REALLY bad. Fortunately there isn't any infection or anything, it just hurts. Now almost all the molars are gone on the right side of my mouth, and I am learning to chew with only my left side. The right side of my jaw was always stronger than my left, so I used it for heavy duty chewing-I used to eat Tic Tacs which are a type of hard mint by the mouthful and chew them on the right side, stuff like that. My mom thinks that maybe the molars became weak over time and with all the drilling that was done over the years.
