Crown Lengthening When decay occurs below the gumline, or a portion of the tooth has fractured, it may not be possible to restore the tooth without a crown lengthening procedure. Sometimes esthetic 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 |
