Hello, 1.5 years ago I received a filling on tooth number 3 on the top right. Filling went well however on occasion it would hurt slightly when biting. About 4 months ago I began to have lingering pain that would come and go on a daily basis. My dentist thought it could be grinding, so I bought a mouth guard. That did not help. I received a root canal 3 weeks ago, an ever since, I have still felt the same pain. Also the tooth was extremely sensitive to the touch post-operation, which I had never experienced before in the past 3 root canals I have had. My endodontist prescribed me some antibiotics, which seemed to help the sensitivity slightly but the lingering pain continued. A few days after the medicine was done, the pain remained present and I went back to the endodontist who removed the root canal inserts and disinfected the tooth with material, sealed it back with a temp filling and told me to give it a week. It is 3 days later and I am still in pain, sensitivity to touch is back, and linger pain still there. Please let me know what you think the problem could be. Mike

  • It looks like that your tooth is still infected. You can wait for some more time or get another dressing done. Sometimes the symptoms are such that when there is crack in the tooth, but your dentist must be knowing that. In your case it looks like, if it is not cracked tooth then it is infected tooth. Retreatment of Root Canal takes longer and it will take some time for symptoms to subside.
