When decay occurs below the gumline, it may be necessary to remove a small amount of bone and gum tissue. Your dentist may ask for this procedure before he or she makes a new crown for your tooth.
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 Gum Surgery 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
Your dentist or periodontist may also recommend crown lengthening to make a restorative procedure possible. Perhaps your tooth is decayed, broken below the gum line, or has insufficient tooth structure for a restoration. Crown lengthening adjusts the gum and bone level to expose more of the tooth so it can be restored with a well fitting crown or bridge.
During this procedure excess gum and bone tissue is reshaped to expose more of the natural tooth. This can be done to one tooth, your gum line, or to several teeth to expose a natural, broad smile.
