Cap that completely covers or encircles a broken or damaged tooth or is attached to a metal post inserted in the jaw (implant) to replace a missing tooth. Crowns may also be used to protect weak or cracked teeth or as a substitute for an extensive filling.
Crowns are installed in two appointments. In the first appointment the tooth to be crowned is filed down to make room for the crown and then an impression is made from which the crown will be molded. Then the impression is sent to the lab to craft the crown. A temporary, acrylic crown may be fitted over the tooth to cover and protect it until the permanent crown is ready if necessary. In the second appointment the permanent crown is cemented into place.
