question: 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 . It's been about 6 days now and I have excruciating pain 24/7 I'm taking both Morton 800 and Tylenol codeine #300 and amoxacilyn but no relief what's 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 don't 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? I'm just not buying when he said that it's just that I can't 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 I'm a nervous wreck in so much pain.
