Functional appliances use the muscle action from speaking, eating,
and swallowing to create forces that move teeth and align the jaws. Some
functional appliances are removable, and others are bonded to the teeth. A
functional appliance may fit between the upper and lower teeth or may span
across the mouth between the molars, pressing the bone outward.
