Crown lengthening is generally performed to improve the health of the gum tissue or to prepare the mouth for restorative or cosmetic procedures. In addition, crown lengthening procedures can also be used to correct a “gummy” smile, where teeth are covered with excess gum tissue. Crown lengthening exposes more of the natural tooth by reshaping or recontouring bone and gum tissue. This treatment can be performed on a single tooth, many teeth, or the entire gum line, exposing an aesthetically pleasing smile.
There are several situations where crown lengthening is necessary. The most common is when there is decay or a fracture that is too far below the gum. The crown lengthening will expose the decay or crack to allow the new crown to properly extend over the area where the decay or fracture occurred. If new crowns or veneers are planned by your dentist, then this procedure sets the stage to allow for a more natural and beautiful smile.
