 Crown Lengthening

Crown lengthening is generally performed in order to improve the health of the gum tissue, or to prepare the mouth for restorative or cosmetic procedures.  In addition, crown lengthening procedures can also be used to correct a “gummy” smile, where teeth are covered with excess gum tissue.  This is performed by extending the height or size of the portion of the tooth that is visible above the gumline.

 

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.

Sometimes people have extra gum tissue which makes their teeth look unnaturally short, and also increases susceptibility to periodontal infections.  Removing excess gum tissue can restore a balanced, healthy look and thus improve the aesthetic appearance of the smile.

If you’ve had dental crowns, crown lengthening will serve 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.

Crown lengthening is usually performed under local anaesthetic.  The amount of time this procedure takes will largely depend in how many teeth are involved and whether a small amount of bone needs to be removed, in addition to the soft tissue.  Your clinician will make a series of small incisions around the soft tissue in order to separate the gums away from the teeth.

Once your clinician is satisfied that the teeth have sufficient exposure, the gum tissue will be cleaned and sutured with small stitches.  The teeth will look noticeably longer immediately after surgery because the gums have now been repositioned.

Following surgery, a mouth rinse may be given to help reduce any bacteria attempting forming and your mouth should be completely healed in approximately two to three months.
