Oral appliance therapy (OAT) is a safe, non-invasive treatment for obstructive sleep apnea and snoring that uses a custom-made mouthpiece to keep the airway open during sleep.
This therapy is a fantastic alternative to continuous positive airway pressure (CPAP), which uses a mask and machine to blow air into the upper airway. Unlike a CPAP machine, an oral appliance moves the jaw forward slightly to help reposition the airway so breathing is less likely to be interrupted.
An oral device is a science-backed approach to treating obstructive sleep apnea. At Foundations: Perio Sleep Aesthetics, oral appliance therapy is a treatment option we see great success with for many patients with sleep apnea. This treatment method could be the thing that brings you back to a good night’s rest. As one of the most effective appliances for sleep apnea, a custom-fitted oral device helps support the airway and reduce nighttime breathing interruptions. A well-designed appliance for sleep apnea can significantly improve airflow, reduce snoring, and offer a comfortable alternative to traditional CPAP therapy.

How Oral Appliances For Sleep Apnea Work
Sleep apnea oral appliances are custom-fitted devices that gently reposition the jaw to keep the airway open throughout the night.
01
Evaluation
Your oral appliance treatment journey begins with a thorough examination from a qualified dentist and sleep specialist. If you haven’t had a sleep test or completed a sleep study, we’ll set you up with an at-home sleep test with our sleep medicine partners.
If your sleep test confirms a diagnosis of mild to moderate sleep apnea and you are a good candidate for oral devices, we will start the process of creating your custom made mandibular advancement device. Many patients find that sleep apnea oral appliances offer a more comfortable and convenient alternative to CPAP therapy. Our team collaborates closely with your sleep specialist to ensure your treatment plan is accurate, effective, and medically supported.
02
Digital Scans & Imaging
We use modern intraoral scanning and imaging to map your bite and airway structure precisely. These digital impressions help ensure a snug fit and comfort for your oral device.
03
Custom Design & Fitting
A custom appliance is designed for your mouth and bite pattern. At your fitting appointment, we verify fit and comfort, make adjustments, and provide detailed instructions for use and care.
04
Future Adjustments
Over several follow-up appointments, we’ll fine-tune your device, adjusting the jaw position to balance comfort with airway improvement.
05
Follow-Up & Long-Term Care
We’ll monitor your progress with symptom checks and follow up sleep testing as needed. Regular dental visits and follow ups help manage fit and detect any bite changes early. Our team works with your sleep physician to ensure coordinated, long term success.
Benefits
These appliances for sleep apnea are custom-designed to keep the airway stable, making them a reliable and comfortable solution for nightly breathing support. Mandibular advancement devices are designed to gently reposition the lower jaw forward, helping prevent airway collapse during sleep. By improving airflow through the upper airway, the appliance helps reduce breathing interruptions and support more restful sleep.
Comfort
Sleek, custom devices are often more comfortable to wear than a mask and hose.
Portability
Small, battery-free, and easy to travel with—ideal for road warriors and frequent flyers.
Ease of Use
Simple nightly wear—no setup, noise, or power required.
Reduced Snoring
Many patients experience dramatic snoring reduction.
Improved Sleep & Daytime Function
Better sleep continuity can translate into more energy, clearer thinking, and improved mood.
Greater Compliance Than CPAP
For many who can’t tolerate CPAP, OAT results in higher nightly use and better real-world effectiveness.
Who Are Good Candidates for Mandibular
Advancement Devices?
Strong candidates for oral appliance treatment or tongue retraining devices include:
- People with mild to moderate OSA who are medically appropriate candidates.
- CPAP-intolerant patients seeking a comfortable, effective alternative.
- People who deal with chronic snoring, excessive daytime sleepiness, or can’t achieve restful sleep.
- Those seeking a dental-based solution integrated with sleep medicine oversight.
People with severe obstructive sleep apnea, however, may be better suited for CPAP therapy. Each case is different–we’ll help figure out which method is most beneficial for you.
Side Effects
Most side effects of sleep apnea oral appliances are mild and temporary:
- Jaw soreness or muscle tenderness for the first few days or weeks.
- Minor bite changes over long periods — we monitor closely and adjust as needed.
- Dry mouth or increased salivation, typically transient. Serious complications are rare when appliances are provided and monitored by experienced clinicians.

Frequently Asked Questions
What is oral appliance therapy for sleep apnea?
Oral appliance therapy (OAT) is a non-invasive, dentist-prescribed treatment for obstructive sleep apnea. It uses a custom-fitted mouthpiece — similar in size to a sports guard — that you wear only while sleeping. The device gently repositions your lower jaw slightly forward, which keeps your airway open and prevents the breathing interruptions that cause sleep apnea. At Foundations Perio Sleep Aesthetics in Chaska, MN, our oral appliances are digitally scanned and precision-fabricated for your exact bite and anatomy.
Is oral appliance therapy covered by insurance?
Yes, in most cases oral appliance therapy is covered under medical insurance — not dental insurance — when sleep apnea has been diagnosed through a sleep study. Most major carriers including Medicare, Blue Cross Blue Shield, Aetna, and Cigna cover oral appliances when medically necessary documentation is provided. Our team at Foundations verifies your benefits before treatment begins and handles all insurance paperwork on your behalf, so you know exactly what you owe before any appointments.
Who is a good candidate for oral appliance therapy?
Oral appliance therapy is most effective for adults diagnosed with mild to moderate obstructive sleep apnea (OSA), as well as patients with severe OSA who cannot tolerate CPAP. It is also an excellent option for people who travel frequently, find CPAP masks claustrophobic, or struggle with the noise and bulk of CPAP equipment. During your consultation at our Chaska clinic, Dr. Strand or Dr. Tiwana will review your sleep study results, medical history, and jaw anatomy to confirm whether an oral appliance is the right fit for you.
How is an oral appliance different from CPAP?
CPAP (Continuous Positive Airway Pressure) uses a machine, hose, and face mask to push pressurized air into your airway throughout the night. An oral appliance achieves a similar result — keeping your airway open — but does so mechanically, by repositioning your lower jaw, with no machine, no mask, and no electricity required. Oral appliances are significantly smaller, silent, and easier to travel with. Many patients who stopped using CPAP due to discomfort, skin irritation, or inconvenience find that they actually use their oral appliance consistently — which is what makes it effective long-term.
How long does it take to get an oral appliance?
The process typically takes 2–3 appointments over 3–4 weeks. At your first visit, we review your sleep study and take a digital intraoral scan of your teeth and bite — no messy impressions. Your custom appliance is then fabricated at a dental lab (usually 2–3 weeks). At your fitting appointment, we place the device, make any initial adjustments, and walk you through how to use and care for it. Follow-up visits over the next few months allow us to fine-tune the jaw position for maximum comfort and effectiveness.
Does oral appliance therapy really work for sleep apnea?
Yes — oral appliance therapy is a clinically proven, evidence-based treatment endorsed by the American Academy of Sleep Medicine (AASM) as a first-line therapy for mild to moderate obstructive sleep apnea. Studies show that properly fitted oral appliances reduce the Apnea-Hypopnea Index (AHI) significantly in the majority of patients. Most patients report noticeable improvements in snoring, daytime energy, and sleep quality within the first few nights. Because compliance rates for oral appliances are consistently higher than for CPAP, real-world outcomes are often comparable — or better — for many patients.
