The bite (occlusion) of your child’s baby teeth is very important. Occlusion refers to how the teeth contact and work together. Problems of the bite can affect a child’s speech, jaw position, appearance and the ability to chew properly.

Genetics determines the size and shape of the teeth and the growth and position of the jaw. Thus, if one or both parents have an overbite or underbite, your child may develop the same profile and occlusion starting with the baby teeth.

What you should see is the following:

  • Normal overjet: All of the front teeth should overlap a little outside the bottom teeth.

  • Normal overbite: The lower front teeth should come up and a little behind the upper front teeth. The space (or contact line) between the upper two middle teeth should be over that of the middle lower teeth.
