Crown lengthening is performed to improve the health of the gum tissue, prepare the mouth for a restorative procedure, or correct a 'gummy smile'. A 'gummy smile' is used to describe when 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/teeth in question to create a new gum-to–tooth relationship. Crown lengthening can be performed on a single tooth or many teeth,.
Crown lengthening is often required when your tooth needs a new crown or other restoration. The edge of that restoration is deep below the gum tissue and not immediately accessible. It may be too close to the bone.
Crown lengthening allows us to reach the edge of the restoration, ensuring a proper fit to the tooth. It may also provide enough tooth structure so the new restoration will not come loose in the future. This allows you to clean the edge of the restoration when you brush and floss to prevent decay and gum disease.
