The treatment option called crown lengthening is available to prepare a tooth for restorative dentistry or to cosmetically enhance your smile.
Restorative Dentistry
When decay occurs below the gumline, 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.
Cosmetic Treatment
Crown lengthening is used to correct what's commonly referred to as a "gummy smile." A gummy smile is apparent when the gumline appears to be creeping down over the teeth, making them appear short.
Your dentist may ask for this procedure before making a new crown for your tooth.
