I had a root canal done in feb and i also got a crown.its been several months n still have pain and sensitivity.themolar also bleeds. what should ido?

See endodontist: See either the endodontist or dentist who did the root canal. The tooth can not be bleeding, it must be coming from around the tooth structure, either gum inflamation or there is still some infection present or there is (hopefully not) a crack in the underlying tooth. See your dentist !

Return to dentist: If gums are bleeding it could be poor fit of crown or you need to floss better pain and sensitivity could be from crown not in occlution {high) or root canal failing or not completly done.

See your dentist. : Some sensations, be it pain or a general awareness, can linger after endodontic treatment. The only way to determine if everything is normal is for you to have your dentist evaluate the tooth in question. Often times the solution is quite simple.

See prosthodontist: See a prosthodontist for an evaluation. They are specialists in replacing and rebuilding missing and broken down teeth, bite assessment and adjustment, crowns, etc. You might need a bite adjustment or new crown with different contours and fit.
