Sleep apnea is a severe sleep disorder that can be treated using an oral appliance. At a sleep apnea treatment clinic, the cost of a dental device to help with sleep apnea can vary based on the severity of the condition, the type of appliance used, and if any additional treatments are needed. If you're looking for a sleep apnea dental appliance, visiting a sleep apnea treatment clinic is best, and we will be able to provide the best possible device for your individual needs.
