Oral appliances are dental devices designed to help with various conditions, primarily sleep-related issues like sleep apnea. They work by repositioning the jaw or tongue to keep the airway open during sleep, improving airflow and reducing snoring. These appliances are custom-fitted by dental professionals to ensure comfort and effectiveness. In addition to sleep apnea, oral appliances can also be used to treat bruxism, a condition where individuals grind their teeth at night. By providing a protective barrier, these devices help prevent tooth damage and alleviate jaw pain. Regular follow-ups with a dentist are essential for optimal results and adjustments.
