Crown Lengthening

When a tooth needs a cosmetic or restorative procedure due to breakage or decay below the gum line, a dentist often performs crown lengthening. Another reason you might consider crown lengthening is when your gum tissue covers too much of your teeth, making them appear short. During the crown lengthening surgical procedure, a dentist exposes a greater amount of tooth structure by making an incision in the gingival tissue surrounding a tooth. The dentist then reshapes the soft tissue to expose more of the tooth or teeth and create a natural, broad smile.
