The roof of your mouth (your palate) is around 80% of the floor of your nose? Mouth-breathing individuals have a tendency to develop a narrow palate, leading to nasal constriction as well as crowding of teeth.
The most common cause of crowded teeth is not that the teeth are too big for the jaws, but because the jaw is too small or narrow for the teeth to all fit in.
Breathing through your nose helps to ensure a correct resting position for the tongue in the roof of the mouth, allowing the tongue to exert forces on the jaw resulting in correct jaw development.
Making the switch from mouth breathing to nasal breathing allows for a wide range of benefits for growth & development & overall health.
