Malocclusion: Causes and Diagnosis

  • Underbite — Your lower teeth stick out over your upper teeth.

The lower tooth (except the central incisor) should make contact with both the equivalent upper tooth and the tooth in front of it. The upper arch overlaps slightly with the lower arch. When the upper and lower teeth make contact with each other, the jaw bones and joints are properly positioned, and movement is unrestrained.
