The most widely used oral appliance for treating sleep apnea is a mandibular advancement device (MAD). This helps reposition the lower jaw to keep an open airway throughout the night.
Another option is a tongue restraining device. This is a splint that holds the tongue in place to prevent airway collapse.
A sleep specialist dentist will examine your case to determine which type of sleep apnea appliance would work best for your sleep apnea treatment.
