Crown lengthening is a common procedure that is routinely performed to re-contour gum tissue and bone, as needed, with the intent of making more tooth structure available for the placement of a dental crown or dental bridge. This is often the case when a tooth is decayed or otherwise damaged below the gum line.
Alternatively, a crown lengthening procedure can also be performed for reasons that are purely aesthetic to reduce the appearance of a “gummy smile” when too much of the gums and far too little tooth structure is displayed when smiling. It can be performed on a single tooth to make the gum line appear even with the other teeth or on several teeth to improve a smile’s overall appearance
