I was recently asked this question following a consultation I did for a patient. A front tooth is beautiful not only because of the white part of the tooth, but also because of how the pink gum tissue drapes around the neck of the tooth. In your smile, there should be a harmonious proportion which flows from the front teeth to the back teeth.
For people whose front teeth have been traumatized, often time the lip line is unconsciously restrained to limit the display the front teeth. If we do not plan for proper gum contouring to create the right proportion and gum tissue drape for the front teeth; when you are happy with the new teeth and begin to smile more openly, then the gum line may throw off the otherwise-could be perfect smile line.
