When dental decay or a tooth fracture occurs below the gum-line, it may be necessary to remove a small amount of bone and gum tissue in order to effectively restore the tooth. A crown lengthening procedure adjusts the gum and bone level to expose more of the tooth so it can be restored properly. If it is not done, the final crown edge (margin) will have to be located deep under the gums, resulting in chronic irritation and soreness. Depending on the circumstances, this procedure may be recommended before a new crown is made for your tooth.
Crown lengthening procedures are done for both restoring teeth and/or to improve the aesthetics of the gum line.
In some cases, crown lengthening is preformed to improve a “gummy” smile where 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 removed and reshaped to expose more of the natural tooth. Your dentist will often use a laser to perform this procedure thereby significantly minimizing any postoperative discomfort.
