Surgical crown lengthening may be used to correct a “gummy” smile, where teeth are covered with excess gum tissue.  In addition, surgical crown lengthening may be used to create more tooth structure for your dentist to place crowns / veneers and fillings where needed.

Reasons for crown lengthening

Here are some of the most common reasons for crown lengthening:

  • Restoration of damaged teeth – Periodontal disease can cause severe damage to the teeth, as can trauma and decay.  Where teeth have been broken beneath the gum line, crown lengthening can be used to prepare the area for a new restoration to correct the damaged teeth.
  • Cosmetic uses – Extra gum tissue can make teeth look unnaturally short, and also increase susceptibility to periodontal infections.  Removing excess gum tissue can restore a balanced, healthy look and thus improve the esthetic appearance of the smile.
  • Dental crowns – Crown lengthening serves to provide more space between the supporting jawbone and dental crown.  This prevents the new crown from damaging gum tissues and bone once it is in place.

If you have any questions about crown lengthening, please ask your periodontist.
