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.
There are two situations in which crown lengthening is commonly performed: to improve appearance, and to allow a dentist better access to decay or provide enhanced tooth structure for a dentist to restore a tooth. However there are two main categories of crown lengthening:
- Functional Crown Lengthening including Biologic Shaping
- Esthetic Crown Enhancement
