Correcting a 'Gummy Smile'
Both bone and gum reduction
Are used to create a more aesthetically pleasing smile when excessive gum tissue is covering up a part of the tooth that should naturally show in a smile.

Whenever a tooth has been damaged by decay or fracture, crown lengthening creates more area for a porcelain crown (even known as a 'cap') to fit over the tooth, lending additional support and preventing tooth loss.
