Types of Crown Lengthening
There are two types of crown lengthening procedures: esthetic and functional. Esthetic crown lengthening is typically performed on front teeth for a “gummy smile,” where front teeth are covered with too much gum tissue. Functional crown lengthening is typically performed when your tooth needs a new crown or other restoration. The edge of that restoration is deep below the gum tissue and typically too close to the bone or below the bone.
Esthetic crown lengthening can be used to expose your naturally beautiful teeth for a more esthetic smile.
Functional Crown Lengthening
Functional crown lengthening involves modifying the levels of the gum tissue and bone around a tooth to create a new gum-to–tooth relationship. This allows your dentist to reach the edge of the restoration, ensuring a proper fit and seal to the tooth. It also provides enough tooth structure so that your new restoration will not become loose in the future. This allows you to clean properly when you brush and floss to prevent decay and gum disease.
