The treatment option called crown lengthening is available to prepare a tooth for restorative dentistry or to cosmetically enhance your smile.
When decay occurs below the gum line, it may be necessary to remove a small amount of bone and gum tissue. Your dentist may ask for this procedure before he or she makes a new crown for your tooth.
If the front teeth are too short or of uneven length, crown lengthening might be indicated. Reshaping the gum and supporting tissues will allow your general dentist adequate room to place a quality final restoration.
Crown lengthening is used to correct what's commonly referred to as a "gummy smile." A gummy smile is apparent when the gum line appears to be creeping down over the teeth, making them appear short.
To correct a gummy smile, it is necessary to remove excess gum tissue, therefore allowing more of the natural tooth surface to appear.
