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 like crowns or veneers. In addition, crown lengthening procedures can also be used to correct a “gummy” smile, where teeth are covered with excess gum tissue. Crown lengthening exposes more of the natural tooth by reshaping or recontouring bone and gum tissue. This treatment can be performed on a single tooth, many teeth or the entire gum line, to expose a pleasant, aesthetically-pleasing smile.


Reasons for Crown Lengthening

Crown lengthening is a versatile and common procedure that has many effective uses and benefits. The vast majority of patients who have undergone this type of surgery are highly delighted with the results.

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

Restoration of badly damaged teeth – Periodontal disease can cause severe damage to the teeth, as well as 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. It allows more exposure of the tooth to have something for a crown to grab onto.

Cosmetic uses – Extra gum tissue can make teeth look unnaturally short, and also increase susceptibility to periodontal infections if the pockets are deep. Removing excess gum tissue can restore a balanced, healthy look, and thus improve the aesthetic appearance of the smile.

Porcelain crowns and veneers – 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.


What does crown lengthening involve?

Crown lengthening is normally performed under local anesthetic with sedation depending on the extent. The amount of time this procedure takes will largely depend on how many teeth are involved, and whether a small amount of bone needs to be removed, in addition to the soft tissue. Any existing dental crowns may be removed prior to the procedure, and replaced immediately afterwards.

Dr. Ramsey Amin will make a small incision around the soft tissue in order to separate the gums away from the teeth. Even if only one tooth requires the re-contour, neighboring teeth are usually treated to provide a more even reshaping. Separating the gums provides access to the roots of the teeth and the underlying bone.

In some cases, the removal of a small amount of tissue will provide enough tooth exposure to place a crown. In other cases, we may also need to remove a small amount of bone from around the teeth. The bone is usually removed using a combination of special hand instruments and rotary instruments. The rotary instruments roughly resemble the drill that is used in cavity treatment. Dr. Amin sometimes uses a very state-of-the-art instrument called a “piezosurgery” unit.

When we are satisfied the teeth have sufficient exposure, the wound will be cleaned with sterile water and the gum tissue will be sutured with small stitches. The teeth will look noticeably longer immediately after surgery because the gums have now been repositioned.

We may secure the surgical site using an intraoral (periodontal) bandage, which serves to prevent infection. Prescriptions will be provided for pain medication, and a chlorhexidine (antimicrobial) mouth rinse may be given to help reduce any bacteria attempting to re-colonize. The surgical site will be completely healed in approximately two to three months. This is generally a relatively painless procedure when done in our office.
