We only perform jaw surgery if it is appropriate, if the patient wants it to be done and the patient is keen to undergo treatment.
It is not always possible to change your teeth and bite using only braces (orthodontics). This is because the bones of your face and jaws, in which the teeth sit, may be out of balance with one another.
Orthognathic surgery is able to improve large gaps between the jaws and balance the shape of your face.
