What is Crown Lengthening?

Crown lengthening is sometimes necessary in order to improve restorative and cosmetic dentistry outcomes. There are two types: functional and esthetic.

Functional Crown lengthening

Functional Crown lengthening may also be recommended by your dentist to make a restorative or cosmetic dental procedure possible. If you wish to save a tooth that is badly decayed, broken below the gum line, or has insufficient tooth structure for a restoration, this procedure is required to keep your tooth healthy. There has to be at least 2 mm of tissue space between your bone levels and the bottom of a filling or crown. Not having this amount of space can lead to inflammation and tooth loss. This lack of space between the jawbone and the crown or restoration margin is known as biologic width violation. Crown lengthening is completed by rolling back the gum tissue, removing some bone around the affected tooth with a surgical drill and then replacing the gum tissue at a lower level to make the tooth look longer or lengthened. The ultimate goal of this procedure is to increase the length of the tooth to allow an adequate restoration on the tooth thereby saving the tooth.
