[|Human|] I had a root canal and crown in January 2012. This past Thursday it was sensitivie again to cold but then that dissipated and Fri, Sat and Sun the tooth [crown area] was extremely painful and throbbing and this morning after taking amoxicillin and Advil, it feels better and I wonder if I should still go see dentist who did root canal to see what may be wrong or if there was an infection and now it is gone?
[|AI|]  Hello and welcome to Chat Doctor forum, I would like to inform you that, pain in a tooth which has already been root canal treated if from infection. The infection can be in the tooth or even in the gums. In order to rule out the cause you should see a dentist. Antibiotics and Advil will provide a temporary relief only, therefore it is important to see your dentist. I hope I answered your query, i wish you good health, take care.
