Crown Lengthening

Crown LengtheningWhen a tooth is fractured or decay extends below the gumline, this area must be uncovered before it can be restored, for several reasons:
•  In order for the gum to heal against the tooth in a healthy manner, there must be 3 millimeters of healthy tooth between the margin of a filling or crown (cap) and the crest of the bone which supports the tooth. This is called biologic width or supra-crestal attachment.
•  A tooth that is broken or decayed below the gumline is difficult, if not impossible, for your dentist to restore correctly since access and visibility are compromised.
•  Inadequate retention form means there is not enough tooth structure left above the gumline to firmly hold a crown.
•  In addition, even the best filling or crown will trap bacteria where it meets the tooth. If this area is below the gumline where you cannot properly clean it, the bacterial accumulation can result in both periodontal problems and new decay.

Cosmetic Crown Lengthening

If you're not happy with your smile, there are cosmetic periodontal and dental procedures available now that could help you achieve the look and smile you want.

Do you have a "gummy smile"? Are your teeth too long? Periodontists today can help you reshape your gumline to expose your ideal smile. In addition, they can work with your dentist to create the foundation for beautiful crowns, veneers, etc. to be constructed on your front teeth.
If you feel that your teeth are too short and your smile is too "gummy" or that your gumline is uneven, covering too much of some teeth, while leaving others the right length, a simple cosmetic treatment might be just right for you.

Crown lengthening and gingivectomy procedures remove the excess gum tissue to expose more of the visible "crown" of the tooth.

Gingival Graft

A gingival graft is designed to solve these problems. A thin piece of tissue is taken from the roof of the mouth, or moved over from adjacent areas, to provide a stable band of dense gingiva around the tooth. There is also a new skin graft product that eliminates taking gum from the roof of the mouth.

Soft tissue grafts and other root coverage procedures are designed to cover exposed roots, to reduce the chance for further gum recession, and to protect your vulnerable roots from decay. Learn more about gingival grafting

A crown lengthening procedure reshapes the gum and bone to solve these problems.
