Crown Lengthening

Why would I need crown lengthening?

Crown lengthening is usually performed to improve the health of the gum tissue, prepare the mouth for a procedure, or correct a “gummy smile”. A “gummy smile” is used to describe an instance where teeth are covered with excess gum tissue resulting in a less esthetically-pleasing smile. The procedure involves reshaping or recontouring the gum tissue and bone around the tooth in question to create a new gum-to–tooth relationship. Crown lengthening can be performed on a single tooth, many teeth, or the entire gum line.

Crown lengthening is often required when your tooth needs a new crown or other restoration. The edge of that restoration is deep below the gum tissue and not immediately accessible. It is also usually too close to the bone or below the bone.

Crown lengthening allows us to reach the edge of the restoration, ensuring a proper fit to the tooth. It should also provide enough tooth structure so the new restoration will not come loose in the future. This allows you to clean the edge of the restoration when you brush and floss to prevent decay and gum disease.

About the Crown Lengthening Procedure

Crown lengthening takes approximately one hour but will largely depend on the amount of teeth involved and if any amount of bone will need to be removed. The procedure is usually performed under local anesthetic and involves a series of small incisions around the tissue to separate the gums from the teeth. Even if only one tooth requires the procedure, it will probably be necessary to adjust the surrounding teeth to enable a more even reshaping. In some cases, extraction of a small amount of bone will be necessary as well.

When Dr. Martin is satisfied that the teeth have sufficient exposure and the procedure is completed, the incisions will be cleaned with sterile water. Sutures and a protective bandage are then placed to help secure the new gum-to-tooth relationship. Your teeth will look noticeably longer immediately after surgery because the gums have now been repositioned. You will need to be seen in one or two weeks to remove the sutures and evaluate your healing. The surgical site should be completely healed in approximately two to three months following the procedure.

Frequently Asked Questions About Crown Lengthening

What is crown lengthening?

Crown lengthening is a dental procedure that removes excess gum tissue and, in some cases, a small amount of bone to expose more of the natural tooth. It may be performed to improve the appearance of a gummy smile or to provide enough tooth structure to support a crown or other restoration.

Is crown lengthening painful?

The area is numbed with local anesthesia to help keep you comfortable during the procedure. Some tenderness, swelling, or sensitivity may occur afterward, but these symptoms typically improve as the area heals. Your dental team will provide instructions to help manage discomfort and support recovery.

How long does it take to recover from crown lengthening?

Initial healing generally takes one to two weeks, although complete healing and gum tissue stabilization may take longer, depending on the extent of the procedure. Your dentist will let you know when you can resume normal activities and when any planned restorative treatment can proceed.

Is crown lengthening only performed for cosmetic reasons?

No. Crown lengthening can be performed for both cosmetic and restorative purposes. It may help improve the proportions of your smile by revealing more of your teeth, or expose additional tooth structure so a damaged tooth can be restored properly.

Are the results of crown lengthening permanent?

Crown lengthening generally provides long-lasting results, although the final appearance depends on your healing, gum health, and individual anatomy. Maintaining good oral hygiene and attending regular dental checkups can help keep your gums healthy following treatment.
