Crown lengthening procedures remove some tissue to expose more of the ‘crown’ of your tooth. 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. This procedure is carried out in the office with local anesthetic.
Crown lengthening may be performed for either "functional" reasons or sometimes for "esthetic" indications.
