Periodontist may also recommend crown lengthening to make a restorative or cosmetic dental procedure possible.

Crown Lengthening and Restorative Dentistry

When decay occurs below the gum line, or has insufficient tooth structure for a restoration, such as a crown or bridge there must be adequate tooth structure. It's a common occurrence that there is not enough tooth structure to attach the restoration and preserve the health of the surrounding gum tissue. The ultimate success of any dental restoration is dependant upon the amount of natural remaining tooth structure. Crown lengthening is a surgical procedure that adjusts the gum and bone level to expose more of the tooth so it can be restored. Crown lengthening is important for the overall strength of the final restoration, providing better health, comfort and function. Reshaping the gum and supporting tissues will allow your general dentist adequate room to place a quality final restoration.

Crown Lengthening and Cosmetic Treatment

Crown lengthening is used to correct what's commonly referred to as a "gummy smile" that hides the beautiful teeth underneath the gums. A gummy smile is apparent when the gum line appears to be creeping down over the teeth, making them appear short. During this procedure, excess gum and bone tissue is reshaped to expose more of the natural tooth and more beautiful smile. This can be done to one tooth, to even your gum line, or to several teeth to expose a natural, broad smile.

Crown lengthening is used to keep the gums around a crown healthy. The gums drape around a tooth and protect the tooth and bone that holds the tooth in the mouth. The gums bond to the tooth surface and this bond prevents food from getting stuck between the tooth and gums. The gums need at least two millimeters of tooth to attach to in order to be effective in preventing food from trapping under the gums, otherwise serious problems can develop.

Sometimes part of a tooth will crack off so that the 2 mm for the gums to bond is not available. Crown lengthening surgery is needed. Another reason that the needed 2 mm might not be available is when a tooth decays and after removing the decay, the dentist finds that there is less than 2 mm of tooth left above the bone. This procedure is used to recreate this needed amount of exposed tooth.

The patient is numbed and an incision is made around the tooth needing crown lengthening. The gum tissue is gently peeled away from the tooth to show the supporting bone holding the tooth in place. Now the dentist can see that there is not two millimeters of tooth available to stick to. In the procedure the dentist removes several millimeters of bone around the tooth to expose the tooth that was previously underneath the bone. After the dentist is sure there is two millimeters or more of tooth sticking out of the bone, the gums are replaced and stitched carefully back in place. The surgery is now complete. The gums are allowed to heal six weeks and a crown can then be constructed.
