Oral Appliance vs. CPAP

Quick answer: CPAP is the most powerful treatment for severe sleep apnea, but many people cannot tolerate the mask. A custom oral appliance is quieter, portable and often worn more consistently, and it is a recognized treatment for mild to moderate sleep apnea and for severe sleep apnea when CPAP fails. The best choice depends on your severity, health and what you will use every night.

Oral Appliance vs. CPAP: Which Is Right for You?

CPAP (continuous positive airway pressure) is the traditional treatment for obstructive sleep apnea, and it works well for many people. But a large number of patients find the mask, hose, and airflow difficult to tolerate — and a machine that stays in the closet doesn't treat anything. For many patients, a custom oral appliance is a comfortable, effective alternative. Dr. Pooja Goel, a Diplomate of the American Board of Dental Sleep Medicine, helps Santa Clara patients understand the trade-offs and choose the right path.

How They Compare

• Comfort & noise: CPAP uses a mask and a motor that pushes pressurized air; an oral appliance is a small, silent device worn like a mouthguard.
• Travel: CPAP means packing a machine and finding power; an oral appliance fits in a pocket.
• Adherence: studies consistently show many patients wear an oral appliance more hours per night than CPAP — and the treatment you actually use is the one that helps.
• Severity: CPAP can treat the most severe apnea; oral appliances are a recognized first-line therapy for mild to moderate OSA and for severe OSA when CPAP can't be tolerated.

You Don't Have to Choose Alone

The right choice depends on the severity of your apnea, your health, and your lifestyle — and sometimes the two therapies are even used together. Dr. Goel works alongside your sleep physician to match the treatment to you. Call (408) 241-6501 or (408) 241-6502 to talk through your options.

What About BiPAP?

BiPAP is a close cousin of CPAP that delivers two air-pressure settings — one for breathing in and a lower one for breathing out — and is sometimes prescribed when standard CPAP is hard to tolerate. Like CPAP, it still involves a mask and a machine. For patients who struggle with any mask-based therapy, a custom oral appliance is usually the most comfortable option they'll actually wear every night, and the one that treats the apnea you don't treat when the machine stays in the closet.
