Most medical problems have at least two possible solutions; surgical and non-surgical. Given that most people do not like to be cut, non-surgical options are by far the preferred option for most patients. For example, if you have some clogged-up arteries in your heart, do you go to a cardiologist or a heart surgeon. From what I understand from my heart surgeon friends, the first stop tend to be cardiologists these days. This is understandable as cutting open your chest to do a by-pass graft scares the living daylights out of most people. Compare this to someone inserting a wire from you thigh up to the heart to unblock the artery. Jaw deformities like an underbite or overbite, within certain limits, can be moderated with non-surgical treatment like orthodontics. But the key is knowing the limitations.
