Why does this matter?
The shape of the inside of the mouth is related to the shape of the upper airway, jaws and face. We all need room in our mouths for our tongue to fit comfortably to allow for unobstructed breathing while awake and asleep. The tongue is just one piece of the puzzle, as there are other causes of airway obstruction that need to be evaluated. The goal of early intervention is the prevention and treatment of obstructive sleeps apneas, prevention of severe tooth crowding, and improved facial aesthetics.
Before adulthood the flat seams or sutures of the palate, and also the bone that holds the teeth, are able to be shaped gently to increase space for teeth, and possibly widen the upper airway as well. The front to back position of the jaw can be adjusted also, to allow the jaw joints and bone to grow into a better position. The causes of the crowded teeth also need to be investigated and ideally treated to prevent relapse.
