Nasal Breathing vs Mouth Breathing
Normal breathing occurs through the nose with the mouth closed and the tongue at rest on the palate. Nasal obstruction results in mouth breathing which puts strain on the muscles of the face and constricts the development of the jaws. The palate becomes narrow, high and long, making it difficult to house our teeth in a straight pattern. The lower jaw not only grows apart from the upper jaw but also becomes positioned further back than normal, causing an overbite.
Causes of Airway Obstruction
- Enlarged tonsils and adenoids
- Nasal blockage due to swollen tissue, allergies of polyps
- Underdeveloped nasal passages, jaw or cheekbones
- Deviated nasal septum
Clear airways increase the chances of proper arch development and straight teeth!
