Crowned root canal still sensitive after 3 months. What is causing this?

Had a root canal on a molar 3 months ago. 2 months ago the permanent crown was put on. Arounnd that time I experienced sensitivity on the tooth when biting and brushing. Not severe, but definitely noticable. I acquired an ache shortly after that time that is pretty constant. The ache was severe at first (kept me up one night.) but gets better if I avoid that area. My dentist took xrays and saw nothing wrong. I went to the endodontist that did the root canal and was examined and he also said no infection is present, but suggested trying some antibiotics just in case. I went to another endodontist and he also saw nothing wrong. The bite has been checked by all three and they all agreed it is perfect. I have been told that there could be a crack in the interior of the root canal. The ache is now very minor as I have been avoiding that area. I want to get an extraction so it will be over. What could be causing this? Should I get an extraction?

Since every dentist you have seen sounds like they are taking the right approach, I would suggest that your tooth is indeed cracked - even under the crown. It has probably been cracked all along, but it is virtually impossible to see a crack in a tooth unless the parts have separated from each other a little bit. Since the tooth lives in a rock - well, in the bone - the pieces often do not separate for a while.





Cracked tooth syndrome sucks. It may be the most unpredictable thing we deal with in dentistry. The worst thing is, the only way to ACTUALLY know how bad the crack is would be to take the tooth out and look at it. If it was a huge through-and-through crack, you would pat yourself on the back and say, "Wise move." If it is a relatively superficial crack that vears off to the side of the tooth, you'd say, "Oh rats, we could have saved it." An x-ray will not generally show ANYTHING with a cracked tooth, because the parts are not displaced from each other.

Reply:Best you call the dentist who did and hear what they got to say.
Reply:It could be a root that your orthodontist didn't see when he performed your root canal. It is especially common in molars to have additional roots branching off the main root.


It would mean you still have sensation in that root, and that is what is giving you problems.





Infection will cause the same problems.

Reply:It could be that the tooth has a crack in it allowing bacteria to get inside the tooth and that could cause discomfort. Sometimes this just happens and can't be avoided.
