Snoring is actually caused by the throat. When the soft palate and uvula of the oral cavity relax, the obstruction of breathing causes the vibration of the soft palate and uvula. The more the obstruction, the stronger the vibration, producing a louder snoring sound. Laser snoring treatment uses laser heat to reach the mucosal tissues in the oral cavity and tighten the related tissues. Once the breathing tract is unobstructed, snoring naturally decreases and sleep quality improves.
