When a tooth is fractured, has a large, old filling, or is severely damaged by decay, your dentist may recommend the placement of a crown. Crowns strengthen and protect the remaining tooth structure and can improve the appearance of your smile. Types of crowns include the full porcelain crown, the porcelain-fuse-to-metal crown and the all-metal crown.

Fitting a crown requires at least two visits to the dentist's office. Initially, the dentist prepares and shapes the tooth for crown. A temporary crown is placed over prepared tooth, while permanent crown is done from lab. On a subsequent visit temporary crown is removed. Then permanent crown is tried on for fit, bite is checked and adjusted. Finally crown is cemented permanently.
