When the lower jaw is forward in relation to the upper jaw, the lower front teeth protrude beyond the upper teeth and an "under-bite" results.
An under bite can be unattractive and can cause uneven wear of the front teeth and jaw joint problems.
In mild cases, conventional orthodontic treatment with braces, elastics, and reverse- pull headgear can be used to correct the problem.
In more severe cases, jaw surgery is required to correct the bite and to create a more harmonious facial profile.
