Treatment overview

Clinical crown lengthening for restoration and smile balance

In some teeth, decay or fracture extends below the gumline and close to the supporting bone. If the tooth can be restored, clinical crown lengthening reshapes the gum and bone to create crown exposure for restoration, so enough healthy tooth structure is visible for a stable tooth restoration.

Crown lengthening may also be used for aesthetic reasons when front teeth appear short and the smile shows excessive gum display. The treatment plan depends on the position of the gumline, the bone level, the desired smile shape, and the final restorative or aesthetic goal.
