I have really bad toothache after composite filling in my molars. its been a week and a half. help!?

Dentist can re-check: A dentist can re-evaluate a tooth if there is pain after a cavity filling. The dentist can see if there is an infection or some other reason for the pain. An endodontist can check for problems with the root of the tooth, and give an opinion on whether a root canal is needed. Meanwhile, the pain medicine recommended by one's dentist, or over-the-counter pain medicine, can help with the tooth ache.

Talk to you dentist: How is you bite? If it feels like you cannot close completely, or if it doesn't feel right, it may need to be adjusted. If the cavity was very deep, it is possible there was so much damage that the nerve was affected on a microscopic level. Composites are a very technique-sensitive material. In some cases, no matter how careful your dentist is, imperfections as the material hardens can cause pain.

Filling too high: It is not unusual to have minor tooth sensitivity after dental work.This should only last 3-4 days. If pain gets worse with time, it is possible that new composite filling is too high. This puts more pressure on tooth when you bite down and causes temperature and pressure sensitivity/pain. A small adjustment should stop all this. If it doesn't, possible cracked tooth, abscess, etc.

See the dentist: You may simply need an adjustment of the filling. But sometimes it may take a few days or weeks for sensitivity to subside.

Irritated tooth: A recent filling can cause temporary tooth inflammation. A tooth can be sensitive to hot/cold and chewing after a recent filling. If the pain continues beyond 4 to 6 weeks or gets very painful you may need root canal treatment.

Go back to dentist: Go back to the dentist and have these checked. Can simply be bite adjusting. Sometimes need to replace them , or send to root canal specialist for evaluation / treatment. Don't wait -- see the dentist. Good luck.

Call your dentist: If the pain persists then it may be because of the deep cavity which is causing pain in the root canal area. See your dentist.
