Prior to a dentist creating a crown, it might be required that a small amount of bone and gum tissue be removed. This generally occurs when there is decay below the gum line.
This procedure is referred to as Crown Lengthening. It is usually performed for improvement of the aesthetics of the gum line or for restorative dentistry. In this procedure the gum and bone level expose more of the tooth allowing it to be restored. Crown lengthening is mostly completed before the restoration of broken or severely decayed teeth
Crown Lengthening procedures are done for both restorative dentistry and/or to improve the esthetics of your gum line. General practitioners often refer for crown lengthening procedures prior to restoration of broken or severely decayed teeth. This procedure adjusts the gum and bone level to expose more of the tooth so it can be restored.
Sometimes crown lengthening is done to improve a “gummy” smile because the teeth appear short. 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
