Two of the most common treatments for obstructive sleep apnea work differently and suit different patients. Understanding how each option works can help you make a more informed decision about your sleep health.
Quick Answer
Both CPAP and oral appliance therapy can effectively treat obstructive sleep apnea. The right choice depends on severity, anatomy, compliance history, lifestyle, and patient preference. For many patients, oral appliance therapy offers better real-world outcomes because it is easier to use consistently.
CPAP — Continuous Positive Airway Pressure — therapy works by delivering a constant stream of pressurized air through a mask worn over the nose or face during sleep. This air pressure acts as a pneumatic splint, keeping the airway open and preventing the collapse that causes apnea events.
CPAP is the most established treatment for moderate to severe obstructive sleep apnea and can be highly effective when used consistently. It is considered the traditional standard of care, particularly for patients with high apnea-hypopnea index (AHI) scores.
However, the requirement to wear a mask connected to a machine by a hose every single night creates significant practical and comfort challenges for a large proportion of patients.
Oral appliance therapy uses a custom-fitted dental device worn during sleep to keep the airway open mechanically. The appliance gently advances the lower jaw forward, which tightens the soft tissues around the airway and prevents collapse.
This approach — part of a field called dental sleep medicine — requires no electricity, no machine, no hose, and no mask. The device is small, portable, and individually fabricated to fit your dental anatomy. Many patients describe it as similar in feel to a sports mouthguard or orthodontic retainer.
Oral appliance therapy is recognized by sleep medicine guidelines as an appropriate primary treatment for mild to moderate obstructive sleep apnea and as a first-line alternative for patients with CPAP intolerance regardless of severity.

For Houston professionals and frequent travelers, treatment portability is a significant quality-of-life consideration. CPAP machines require carrying a device, power adapter, humidifier, hose, and mask — along with voltage adapters for international travel. Many patients find this impractical for business trips, vacations, or weekend travel.
A custom oral appliance fits in a small case that can slip into a pocket, purse, or carry-on bag. There is no power source required. Patients frequently report that the portability of oral appliance therapy makes consistent use far more realistic.
Compliance — using the treatment every night for the full duration of sleep — is the single most important predictor of treatment success. CPAP is highly effective when used properly, but studies consistently show that 30–50% of patients do not achieve adequate nightly compliance.
The most effective treatment is the one a patient will actually use, consistently, every night. For many patients, oral appliance therapy achieves significantly higher compliance than CPAP because of its comfort and simplicity. This real-world consistency often translates to better overall health outcomes.
The right treatment depends on a combination of individual factors. Treatment decisions should be made in consultation with your provider based on:
