Custom Oral Appliance Therapy for Sleep Apnea in Lenoir City
If you’ve been diagnosed with sleep apnea—or suspect you have it—and CPAP isn’t working for you, oral appliance therapy may be the solution you need. At Sleep Well East Tennessee in Lenoir City, we provide custom-fitted oral appliances as a comfortable, CPAP-free alternative. As a dedicated dental sleep medicine practice, we focus entirely on helping you breathe easily and sleep well. We accept Medicare, VA, and most commercial insurance plans to make treatment accessible.
What Is Oral Appliance Therapy?
Oral appliance therapy uses a small, custom-fitted device worn in your mouth during sleep to keep your airway open. It is a clinically proven treatment for mild to moderate obstructive sleep apnea and is also an effective alternative for people who cannot tolerate CPAP. The device looks similar to a sports mouth guard but is precisely engineered to hold your jaw in a forward position, preventing the airway collapse that causes apnea events.
How a Mandibular Advancement Device Works
The most common type of oral appliance is a mandibular advancement device—a custom-fitted oral device that gently shifts your lower jaw forward to keep your airway open while you sleep. By advancing the jaw slightly, the device tightens the soft tissues and muscles of the upper airway, reducing the likelihood of collapse. This simple mechanical action can dramatically reduce or eliminate apnea episodes and restore healthy sleep.
Who Is a Good Candidate for an Oral Appliance?
You may be a candidate for oral appliance therapy if:
- You have been diagnosed with mild to moderate obstructive sleep apnea
- You have tried CPAP but found it uncomfortable, noisy, or restrictive
- You prefer a more portable and discreet treatment option
- You snore heavily and your sleep study suggests airway obstruction
During your consultation at Sleep Well East Tennessee, we review your sleep study results, medical history, and symptoms to determine the best approach for your situation.
What Happens If Sleep Apnea Goes Untreated
When sleep apnea is treated effectively, patients often notice more energy, better focus, and improved overall health. Without treatment, untreated sleep apnea can worsen over time—contributing to high blood pressure, heart strain, daytime fatigue, and an increased risk of accidents. The good news is that effective, comfortable treatment is available, and we’re here to guide you through it.
Benefits of Oral Appliance Therapy
Oral appliance therapy offers a range of advantages for people seeking an alternative to CPAP:
- Comfort: A custom-fitted device made from soft, durable material that adapts to your mouth

Oral Appliance Therapy vs. CPAP: How They Compare
Both treatment options are effective, but they work differently. Here’s how they stack up side by side.
Side-by-Side Comparison
| Feature | Oral Appliance Therapy | CPAP |
|---|---|---|
| Device type | Custom-fitted oral device | Mask + air pressure machine |
| Portability | Travel-friendly, compact | Bulky, requires power source |
| Comfort | Worn in the mouth, no straps | Full mask, air pressure, tubing |
| Noise | Silent | Machine noise during operation |
| Compliance rates | High among CPAP-intolerant patients | Lower due to discomfort |
| Insurance coverage | Medicare, VA, commercial plans | Medicare, VA, commercial plans |
| Best for | Mild–moderate OSA; CPAP intolerant | Moderate–severe OSA; CPAP tolerant |
For many patients, the choice comes down to lifestyle and comfort. If CPAP hasn’t worked for you, oral appliance therapy may be exactly what you need. Learn more about your options on our CPAP alternatives page.
