If teeth are decayed or broken below the gum line, crown lengthening is often necessary in order to restore the teeth. Since the procedure adjusts the gum and bone levels to expose more of the tooth surface, it is easier to restore these teeth with cosmetic fillings and crowns.
Crown lengthening is often performed for cosmetic purposes, as well. One such indication is crown lengthening to improve a “gummy” smile. This involves reshaping excess gum and bone tissue to expose more of the natural tooth. The procedures can be performed for a single tooth to even the gum line or for multiple teeth to improve the appearance of the entire smile.
