Causes of OSA

Patients suffering from OSA lose their breath because the tongue falls back and blocks their upper airway. It happens because the muscles at the back of the throat over-relax, letting the tongue slip from its place.

Breathing disruptions, sometimes happening up to 30 times in a given night, can cause a dip in the level of oxygen in the blood, and in turn, lead to a build-up of carbon dioxide.

The rest of what happens, including the clenching of the teeth and the subsequent pain in the jaw, are a result of the body’s compensatory reaction — the brain telling the jaw to move forward to clear the airway. When the jaw moves, it forces the teeth into a clench, thereby causing pain.
