Sleep Apnea Mouth Guard vs. CPAP

What is the difference between a sleep apnea mouth guard and CPAP?

CPAP (continuous positive airway pressure) delivers a steady flow of air through a mask, which holds the airway open. A sleep apnea mouth guard is a custom appliance worn over the teeth that positions the lower jaw forward, which keeps the tongue and soft tissues from blocking the airway. CPAP is prescribed by a physician, and an oral appliance is made and adjusted by a dentist as part of that medical plan.

How does CPAP work?

A small bedside machine sends pressurized air through a tube to a mask over the nose, mouth, or both. The air pressure acts as a splint that keeps the airway from collapsing during sleep. CPAP is a standard first treatment for obstructive sleep apnea and is managed by a sleep physician.

How does an oral appliance work?

A mandibular advancement oral appliance holds the lower jaw in a forward position during sleep to help maintain an open upper airway. Dr. Lee takes records of your teeth and bite so the appliance fits closely, then adjusts it over time. Your physician confirms how well the appliance is working with follow-up sleep testing.

How do they compare?

Who is a sleep apnea mouth guard a good fit for?

An oral appliance often fits adults with mild to moderate obstructive sleep apnea, and people with more severe sleep apnea who cannot use CPAP. Healthy teeth and gums are needed to hold the appliance, along with jaw joints that can comfortably move forward. Dr. Lee evaluates these before an appliance is made.

When is CPAP the better fit?

CPAP is often recommended for moderate to severe obstructive sleep apnea, where it is the most consistently effective treatment. It may also be the better fit when there are not enough healthy teeth to hold an appliance. Some people use both, such as CPAP at home and an appliance when traveling, as their physician directs.

How does Dr. Lee fit into your treatment plan?

An oral appliance is made after a physician diagnoses sleep apnea, as part of that medical plan. Dr. Lee evaluates your teeth, periodontal support, jaw joints, bite, and restorations to see whether your mouth can hold an appliance comfortably. She then makes and adjusts the appliance in coordination with the plan from your physician.

What affects the cost?

The cost of oral appliance therapy depends on the appliance and the follow-up visits needed to adjust it. Coverage varies, and some medical plans cover oral appliances for diagnosed sleep apnea. Our team can review your dental benefits and the expected cost with you before treatment begins.
