Is it normal to still have nerve pain from crowned tooth, over a month later?

fixing teeth can be a challenge.  While often JUST a crown is all that it needs, sometimes a teeth needs a root canal treatment.

Most likely your tooth is just healing up from the procedure of placing a new crown.  Many people experience this, but it usually goes away within a few days to few weeks.  As long as the discomfort is getting less over time, you have a good chance it will eventually completely go away.  However, if it gets worse, or no improvement whatsoever at the six month mark, would suggest having it evaluated by a root canal specialist (endodontist) to determine if your nerve irritation is chronic and irreversible, thus needing a root canal.For the meantime, just give it some time to calm down.  The vast majority of times it goes away and no root canal would be necessary.

No, it is no normal.  You can have some sensitivity but not the pain you are describing. If your bite seems fine, it could be that the crown was placed wrong and it needs to be redone. This happens. Sometimes the dentist does not get it right!  I would go back to your dentist or seek a second opinion before you see him. Either the crown was not placed correctly, or there is a chance that he drilled to far down or the decay was further into the tooth and needed a root canal. It could be either one of these scenarios. Get a second opinion and get it taken care of soon!
