Crown lengthening is a procedure that may be performed before a restorative procedure, or for aesthetic purposes.
In cases of restoration, if a tooth is badly broken or decayed, your dentist may need to remove a small bit of bone and gum tissue in order to expose more of the tooth and ready it for a crown, as a certain amount of tooth must be accessible to allow a crown to hold.
Crown lengthening can also be done to fix a smile that a person may think is too “gummy”, making their teeth look small when compared to their gums. In these instances, the teeth are often normal sized and not too small, but excess gum tissue grows over the top of the teeth hiding a portion and giving them a smaller appearance. A crown lengthening is used to expose more of the natural tooth and create a less prominent gum appearance.
