Crown lengthening involves the precise removal of excess gum tissue and bone to reveal more of the tooth's surface.
If your cavity is large or deep towards the gums, crown lengthening may be recommended as part of the treatment plan. This is done to prepare teeth for treatments like crowns or bridges if there is not enough tooth structure to support a restoration. In some cases, crown lengthening can be used to improve the appearance of your smile by making the teeth and gums look more in proportion.
