A closed bite is where the upper front teeth extend over the
lower front teeth causing the lower front teeth to bite into
the roof of the mouth. Deep bites are inherited and usually
develop due to a receding underdeveloped lower jaw.
Closed bites contribute to gum recession and excessive wearing on
the upper and lower front teeth due to occlusal trauma, inefficient
chewing function and misalignment of the jaw joints.
Treatment of deep bites is ideal during a facial growth period.
At this time the lower jaw and teeth can be developed in a more
forward and downward vertical position to correct the deep bite.
Functional appliances, headgears and full orthodontic braces are
used in various combinations to achieve an ideal occlusion. In
adults, deep bites can sometimes be corrected orthodontically, but
in severe cases jaw surgery may be required.
