Before we dive into how oral appliances work, it's helpful to understand what causes the issues they treat. The most common type of sleep apnea is called obstructive sleep apnea (OSA). This happens when the muscles in your throat relax too much during sleep, causing the soft tissues to collapse and block your airway. When your airway is blocked, you temporarily stop breathing, which can happen hundreds of times a night.
Your brain senses this lack of oxygen and briefly wakes you up to restart breathing, often with a gasp or snort. While you might not remember these awakenings, they severely disrupt your sleep quality, leading to daytime fatigue, irritability, and other health concerns. Snoring is often a primary symptom, caused by air struggling to pass through a narrowed airway. You can learn more about what obstructive sleep apnea is and its symptoms on our website.
