A crown is an indirect restoration that is needed when a tooth has a large cavity, a large existing filling that needs to be replaced or a fracture. When 50% or more of the chewing surface of the tooth is compromised a crown is indicated in order to stabilize and protect the tooth. Posterior teeth that are in need of root canals also require crowns to stabilize the teeth. There are several different materials that can be used to restore a tooth with a crown. Most common restorations are all porcelain, zirconia and porcelain fused to metal. Your dentist will discuss your specific case with you to determine the best restoration to maximize both aesthetics and strength. The appointment time allotted for a crown is generally about 1.5 hours and is completed with a local anesthetic to numb the tooth.
