I had a root canal done on a fractured large bottom molar. After the procedure, a crown was fitted in. Two months later, it started hurting. The dentist said the nerve was dead so it should not be hurting and that it must be the tooth in front of it, which was hurting. This tooth does not indicate any problem. I went to a specialist for a second opinion and he could not see anything wrong either. The pain was terrible; just sucking in air hurts. Does anyone have similar situation? Can the dentist take the crown off to see if it was mush or not? The tooth beside it does not give me any problem and the dentist cannot tell for sure if it was causing the pain so I don’t want to mess with it. I can feel that the pain comes from the canaled molar. Any thoughts? Please help! Thanks.
