My tooth hurts and i went to get a root canal and still hurts everyday and i want this pain to go away cand im home and its nigh help

I : I assume that your root canal is completed. It is not unusual to have some pain after completion of the treatment due to residual inflammation of the tissues around the root of the tooth. This can be managed with Motrin or advil (ibuprofen). I may also be present if there was an infection in the bone as a result of the death of the nerve. If the discomfort does not slowly resolve contact the dentist who performed the procedure for instructions. ...Read more

Get the tooth checkd: The concerning part here is the past history of a root canal. Many upper molar teeth commonly have complexities that contribute to a later infection. This infection can often spread to the sinus, so the 2 could be linked. I would not take an antibiotic without first being evaluated. An endodontist (preferrably one with a ct scanner) and that uses a micrscope would be best able to assess you. ...Read more

I had a root canal 2days ago. Still lot pain.My concerne is that i feel exectly the same way - cold... Hot... When touchs my tooth hurts really bad.?

Multiple causes?: It is possible that (1) the root canal treatment is not fully completed. (2) it is "completed" but a canal was "missed" and a nerve is still signaling hot / cold sensitivities. (3) you had two teeth in need of therapy and only one was treated . (4) the wrong tooth was treated. If your dentist (specialist or g.P. Is unable to determine the cause, get a second opinion from an endodontist. ...Read more

Tooth pain started 3 weeks after perm crown. Dentist: wait, see if the nerves correct themselves. Root canal? Wait? Heat hurts and can't chew food

RCT: Sensitivity to heat is especially a classic sign of nerve involvement and the need for root canal therapy. Pain on biting pressure can be merely the bite being high and the need to adjust the bite. However, both symptoms combined along with the course of events that you describe would make the need for rct very likely. I think 3 weeks is long enough to wait for resolution. See your dentist now. ...Read more
