A crown is a cover or “cap” your dentist can put on a tooth. The crown restores the tooth to its normal shape, size and function. The purpose of a crown is to make the tooth stronger or improve the way it looks.
● You may need a crown if you:
● have a cavity that is too large for a filling
● have a missing tooth and need a bridge
● need to cover a dental implant
● have a tooth that is cracked, worn down otherwise weakened
● have had root canal treatment—the crown will protect the restored tooth
● I want to cover a discolored or badly shaped tooth and improve your smile!
Several steps are involved, and two dental visits are generally needed to complete the treatment.
● The dentist prepares the tooth by removing itsouter portion so the crown will fit. Any decay is also removed. If additionaltooth structure is needed to support the crown, the dentist may build up thecore of the tooth.
● An impression is made to provide an exact modelfor the crown.
● You will get a temporary crown while you waitfor the permanent crown to be ready—usually less than two weeks. While you havethe temporary crown, this tooth may be sensitive to hot and cold. Also, avoidchewing gum or sticky foods during this time.
● The dentist or a laboratory technician thenuses the model to help make the crown.
● When the new crown is ready, the dentist placesit in your mouth and makes the necessary adjustments. When you and your dentistare satisfied with how it looks and feels, the crown is cemented in place.
