How it works
The root cause of snoring and obstructive sleep apnea is excessive relaxation of the muscles at the back of the throat during sleep, narrowing the airway. When air flows through this narrow passage, the relaxed soft tissues (such as the soft palate, uvula, and tongue) vibrate, causing snoring. If the airway is completely blocked, apnea occurs.
- Advancing the Mandible: A snoring device acts like a mouthguard, covering both your upper and lower teeth. Its special design guides your mandible to a slightly forward position during sleep (usually 2-6 mm).
- Tongue Retraction: Mandibular advancement indirectly moves the muscles at the base of the tongue forward, as the tongue is attached to the mandible.
- Widening the Airway: By advancing the tongue and mandible, they prevent them from falling back and blocking the throat. This significantly widens the airway from the back of the mouth to the throat, allowing airflow to flow more smoothly, eliminating soft tissue vibration (snoring) and airway obstruction (apnea).
