In order to keep your sleep apnea oral appliance in good condition for maximum efficacy, Dr. Vivian Throop and our team recommend you brush and floss your teeth each night before you wear it. This will help keep plaque and bacteria from building up inside of the oral appliance. To clean your sleep apnea oral appliance, we suggest that you use a soft-bristled toothbrush with toothpaste daily and soak the appliance in denture cleaner once a week. If you notice any cracks or other signs of damage, call City of Oaks Dental for a replacement.
