question: I had a root canal re-treatment on 7 Feb on a lower bottom molar on the right side of my mouth. Following the procedure I experienced basically no pain for the first 6 days and ate everything but attempted to chew on the left side. On 13 Feb while traveling out of town, I felt severe pain in my right upper jaw joint when opening my mouth to eat. I returned to the dentist as a walk-in on 22 Feb and saw another dentist who took x-rays and examined my mouth. He determined there was no infection or fracture but assumed I had strained a jaw muscle. I instructed me to eat soft foods, take Motrin and muscle relaxers to treat the problem. It is now 24 Feb and the pain still exists and I don t know what to do. The main problem is experiencing pain in the upper part of my right jaw joint area. Can you please tell me what I can do to relieve the pain? I am scheduled to return to the dentist on 28 Feb to have the procedure completed but I don t know how or if I will be able to open my mouth wide enough with dying of pain to have it done. Please help?
