Teeth can develop deep decay or even fracture at or below the gum line. In this case, your restorative dentist is generally unable to restore the tooth with a crown or bridge. Crown lengthening can increase the amount of tooth structure above the gum line, giving the restorative dentist more tooth structure to work with.
