The Dental Crown Procedure
Depending on the extent of the decay or damage to the tooth, the dentist may perform a root canal before placing a crown on the tooth. If this is the case, the dentist may need to build a foundation for the crown after the root canal has been performed, also known as a "post-and-core" foundation.

Before the crown can be placed on the tooth, the dentist must file the tooth down to make room for it. Then an impression of the tooth and the surrounding teeth will be made. While the crown is being created, a temporary acrylic crown will be placed on the tooth.

When the permanent crowns are ready, the temporary crowns are replaced at a separate visit. The crown will last anywhere from seven to 40 years.
