THERE IS A CONDITION CALLED MICROGNATHIA WHERE THE LOWER JAW IS SEVERLY SHORTENED. THIS CAN CAUSE A MULTITUDE OF SELF ESTEEM PROBLEMS AS THE CHILD GROWNS.

When I see this type of deformity, it is a tell tale that the Jaw joint may be displaced. 150 or so years ago, a pediatrician in Paris published his views along these lines. You might want to research this for yourself.
(malocclusion) Speech deformalities, crowding of teeth, thats about it.
It's been medically proven that children who's teeth have severe malformations such as overbites suffer later in life. They may have weight problems that comes from not being able to chew as properly or appropriately due to the placement of their teeth. Somehow it also connects to possible heart problems later in your child's life. And trust me, it's so much easier to just pay for your child's braces now while their young than see them in ten years wishing you'd done it.
