Crowns/Root canals
I recently had a root canal performed on a tooth that has a crown. The crown was placed less than a week ago, however, I experienced excruciating pain with hold and cold foods.

Last year, I was in a similar situation. First, is it normal to have to have a root canal after you receive a crown? The reason for this question is before I received the crowns, I experienced no pain.

And final question is: is it okay to keep your existing crowns after a root canal is performed? I have been advised by my dentist that the crowns are still good. ...Visitor from GA

Sometimes putting a crown on a tooth will seem to make the tooth start hurting and need a root canal. The tooth's nerve was probably going bad from decay or a previous deep filling. But normally, the crown does not CAUSE the need for a root canal.

You don't always have to have a new crown made after a root canal. There are exceptions, usually cosmetic in nature. Just make sure the root canal access opening in the crown is properly filled in.
