When decay occurs below the gumline, it may be necessary to remove a small amount of bone and gum tissue. Your dentist may need to perform this procedure before he or she makes a new crown for your tooth.
Crown lengthening is done for restorative dentistry and can also be done to improve the aesthetics of your gumline. General practitioners often refer patients to a specialist for crown lengthening prior to restoring broken or severely decayed teeth. This procedure adjusts the gum and bone level to expose more of the tooth so that it can be restored.
Sometimes crown lengthening is done to improve a “gummy” smile, which is characterized by the appearance of short teeth. The teeth may actually be the proper length, but excess gum tissue may be covering these teeth. During this procedure, excess gum and bone tissue is reshaped to expose more of the natural tooth.
