Malocclusion is a faulty bite. Most of the time, it happens because the size and shape of the teeth don’t match that of the jaws. It can also happen because the upper and lower jaws don’t match each other and the other bones of the face. A look at your child’s profile (side view of the head and face) may help you to see whether there is a problem with the growth of their jaw and facial bones.
The genetics of the parents determine the jaw growth and tooth size of children. Tooth decay of the baby teeth, premature loss of baby teeth from tooth decay and crowding are major causes of malocclusion. Premature loss of baby teeth due to lack of jaw space from erupting adult teeth also causes malocclusion.
