Obstructive sleep apnea is when your airways become either partially or entirely blocked while you are asleep. It is the result of the muscles of the throat relaxing to a point where they collapse and close off the air supply. Fortunately, the brain will wake you up to resume breathing. Sometimes, you will be fully roused, and other times, you will not become fully conscious. However, either way, it is interrupting your sleep and making you susceptible to other health challenges that come from lack of sleep. If you have not had success with a CPAP device in addressing your obstructive sleep apnea, a dental appliance may be an option for you. The goal of dental appliances is to keep the airways unobstructed by opening up the jaw and preventing the tongue from collapsing back into the throat. Patients are given a screening questionnaire to see if they may be at risk for obstructive sleep apnea. If they are at risk, a medical provider will order a sleep study to diagnose obstructive sleep apnea more definitively.
