What is Ada procedure code D4249?

ADA procedure code D4249 refers to the "Clinical crown lengthening - hard tissue" procedure in dentistry. This code is used when a dentist performs a surgical procedure to remove bone or gum tissue to expose more of the tooth structure for restorative or cosmetic purposes. It is typically necessary when there is insufficient tooth structure above the gum line for proper restoration. This procedure is often used in preparation for crowns or other dental restorations.
