Dental pain after post and temp crown

by srost, Feb 13, 2007 12:00AM
6-8 weeks ago, my endodontist did RCT on teeth numbers 2 and 3.  Prior to RCT, number 3 had severe pain due to inflamed pulp but no infection, number 2 had decay but no pain or infection.  (RCT was recommended on 2 to avoid having to drill through a crown later on.)  Both teeth felt better after RCT, and even chewing caused no pain.
Two weeks ago, I went to my dentist for posts and crowns on 2 and 3.  While she was grinding down the metal post on 3, I started to have severe pain.  She explained that the heat that was produced from the grinding had travelled through the post, and so she gave me an additional shot of novacaine.  My concern is that two weeks later, I am not able to bite down on anything with that tooth without having pain.  The tooth does not touch the lower teeth when I bite, and I have no pain as long as I am not chewing.  However, the pain when chewing is severe, and it feels like the post is jamming up into my jaw or something.  Is it possible that she "burned" the root area, and I just need some additional time for that to heal?  Also, would an x-ray show if the tissue was damaged, if the post is too long, etc...  or do I just have to wait it out?  I am supposed to go in two weeks for the permanent crowns, and I will not let them put those on until this pain issue is resolved.  Any advice is appreciated.

My concern would be the placement of the post--an x-ray would tell you the position of the post. Correctly so I would not place the crowns on the teeth unless they are asymptomatic.I think you should see the doctor asap.

if you were fine before the post, and are now having pain upon chewing after the post was placed, it sounds like the post placment is the culprit. ALot depends on what type of post was used (screw type posts can split the roots they are placed in if they are screwed too tightly) and the post hole itself-- it is not difficult to perforate through the side of the root during the drilling of the post hole. I'd have an xray taken, and then if your dentist sees no problem, take the film to another dentist for a second opinion.
