First I went in for small filling on upper left 2nd molar 1 month ago. Ever since then I have crazy pain when I eat or drink hot or cold. Last week dentist could not understand why I had pain cause it was such a small filling but after examination he started a root canal saying that this will relieve any sensitivity and I would get immediate relief . Its been about 6 days now and I have excruciating pain 24/7 Im taking both Morton 800 and Tylenol codeine #300 and amoxacilyn but no relief whats so  ever. This morning the dr checked me. First he pushed hard on the gums around the area and I felt no pain. Then he pushed hard with his finger on the tooth and I felt no pain. The dr could not believe it. He then touched the tooth with a pick and I had pain. He proceeded to open the tooth by taking out the temporary filling without novacane and saw no puss and no infection. He claims I just dont tolerate pain very well. He also said he will not even attempt to finish the root canal until my pin subsides. Could my dentist be missing something? Im just not buying when he said that its just that I cant handle pain that well cause on a scale of 1-10 my pain was at an 11! 24 hours a day ever since that first treatment. What could it be what can I do??? Please help Im a nervous wreck in so much pain.

Hello! Thank you for posting here. You did not mention if you had any pain in that tooth before the small filling. This tooth can be a case of vertical fracture. Fracture lines can be often missed in the radiograph and lead to unexpected pain and discomfort in the tooth. You did not mention if you grind your teeth in the night. Your dentist is right in not proceeding unless there is a relief in the pain. Completing the root canal will merely be namesake and there will be no improvement in the pain relief. I suggest you to get this clarified with your dentist. Hope this helps.
