What is a perfectly proportioned mouth?

According to hours of research done by plastic surgeons all over the world – the perfect mouth has these characteristics:

  • The width of the mouth should be roughly 1.6 times the width of the bottom of the nose (what a coincidence — the golden ratio?).
  • If you drop lines down from the inner part of the colored part of your eyeballs, your mouth should fit right between those two lines.
  • Research shows that women tend to prefer upper front teeth that are rounded and men like a more square look, but it does seem that most of us prefer the height of the two front teeth to be about 1.6 times the width (golden ratio?).
  • The front six teeth also should follow the golden rule that we discussed earlier — with the larger ones being 1.6 times the size of the each successive smaller one.
  • Your upper incisor (front) teeth should be visible below your upper lip for one to four millimeters and your lower teeth should not be visible when your lips are open. As you get older, the upper lip lengthens and you see less of your upper teeth. At the same time, your lower lip sags, exposing more of your lower teeth. When Shakespeare mentioned older people as “long in the tooth” he was describing this drop. The real reason for “long in the tooth” is periodontal disease, where the gum recedes and the bone follows. That creates triangles of space between the teeth and exposes their roots.
  • The upper lip should be slightly larger than the lower lip with a gentle curve that peaks at what’s called cupid’s bow. The hinge of the upper lip comes in the form of the central philtrum that separates the two sides.
  • Your upper teeth should also overlap the lower teeth by one millimeter.
  • Your jaw should be level. How can you tell? Take a double-wide Popsicle stick and bite on it. If your jaw is asymmetrical, the stick will tilt.
