To create harmony between the tooth form and face, teeth of females may be more ovoid or tapering than square as compared to males. The incisal edges may also be rounded for females. Square feature is associated with masculinity.
Personality: A vigorous personality requires square teeth with flat incisal edges, while a delicate personality will require ovoid teeth.
