Excessive vertical overlapping of front teeth called “overbite” is generally found in association with a discrepancy between the length of the upper and lower jaws. It usually results in excessive eruption of either the upper or lower front teeth or both.
Associated problems include: 1) Gummy smile appearance, 2) Lip protrusion or incompetence, 3) Biting the roof of the mouth, and 4) Unwanted wearing of enamel.
