Our bodies need fresh air as a source of Oxygen. However, excessive breathing actually prevents Oxygen availability and its absorption
by body cells and organs. That is because of another key ingredient of air which is Carbon dioxide.
We also need sufficient CO2 in our blood before red blood cells will release Oxygen to be used by the body. Fast and frequent deep breathing
leads to excessive exhalation and loss of CO2 and therefore Oxygen gets bound up to hemoglobin molecules in red blood cells and becomes
unavailable. The other function of CO2 is to help widen the diameter of blood vessels. Lack of CO2, causes veins to reduce in size and blood
can stagnate or “pool” in some areas leading for example to dark shadows under the eyes. In addition, breathing through the nose allows for
Nitric Oxide to be added to the air. Nitric Oxide kills harmful germs, increases Oxygen absorption in the lungs and also improves blood flow.
The dental ramifications of habitually breathing through the mouth instead of the nose include:
1. dehydration leading to dry mouth and demineralization of tooth enamel. This can lead to cavities and gum disease,
2. low mandible and tongue position because of an open mouth. This leads to crowded teeth and sinus problems.
When the lips are together the tongue usually rests in the roof of the mouth. Here it shapes the palate into a wide
and spacious form with more room for the teeth. Also, the upper parts of the face and the sinuses develop better.
Treatments include:
1. Treat any breathing obstructions like tonsils, polyps or adenoids. your GP/Dentist and an ENT specialist can help.
2. Consider a breathing training program (Myobrace) at participating dentists to establish correct breathing habits.
