Crown lengthening is performed for a number of reasons including:
During the procedure you will first get your teeth cleaned by the dental hygienist. The dentist will then give you a local anesthetic so that your gums are numbed during the procedure. Depending on the reason for the procedure the dentist will accordingly remove and restructure the gum and the supporting bone. Once the tooth or teeth have been sufficiently exposed and the procedure completed, the dentist will suture the remaining gum tissue back in place.
The duration of the procedure depends on how many teeth need to be treated and the extent of damage to the teeth.
