A smile that is said to be "superior" is a significantly smaller deviation of smile angles.

The more parallel the two lines are, the more beautiful the smile is, if there is a "corner" , it should only be 0.97 degrees for celebrities and 1.33 degrees for students.

The study authors, Dr. Vasiliki Koidou of the University of Minnesota in the US shared: "A smile that is considered" high-class "is that there is a significantly smaller deviation of smile angles, this angle only should be less than 1 degree ".
