I had a root canal done 3 months ago, and less than 30 days later I went back to general dentist who did a build up and temp crown. It has been almost 2 months and I am experiencing pain when I touch the tooth. I have no nerve left in the tooth, how can this happen? I had no pain what so ever after the root canal, only after the temp crown was placed on tooth. The bite feels normal so I can't imagine what the problem is? Please help! I have already spent so much money..
