Crown lengthening is a dental procedure that involves the removal of gum tissue or bone to expose more of a tooth’s surface.

This is typically done to improve the appearance of a “gummy” smile or to provide more tooth structure for a dental restoration (such as a crown or bridge). Crown lengthening may also be done to improve oral health since it reduces the depth of gum pockets around teeth; this makes your teeth easier to clean and less susceptible to disease.
