Functional orthodontics consists of not only straightening a person’s teeth, but also creates a better facial profile by repositioning the upper and lower jaws. If a person has a poor alignment of either the upper or lower jaws, their bite may be thrown off. As a result, this can lead to: migraine headaches, neck pain, shoulder pain, sleep apnea, ringing in the ears, TMJ dysfunctions, upper airway obstruction, and poor facial profiles.
