Learn how sleep apnea mouth guards help keep your airway open during the night to reduce snoring and improve breathing.
How Do Sleep Apnea Mouth Guards Work?
When the breathing passage narrows or closes entirely while resting, it causes obstructive sleep apnea (OSA), resulting in decreased oxygen in the bloodstream and paused respiration. Sleep apnea mouth guards, also known as oral appliances, treat this by physically repositioning the tongue or jaw to prevent the airway from closing.
These devices are different from standard guards used for sports or teeth grinding. They specifically target structural issues, such as a tongue that slides back into the throat or a small lower jaw.
Types of Oral Appliances for Sleep Apnea
Different designs are used depending on the cause of the airway blockage:
- Mandibular Advancement Devices (MADs): These push the lower jaw forward. They may come in a single-piece design or a two-piece version. Two-piece models allow more jaw movement, which some find more comfortable, though they may be less ideal for back sleepers.
- Tongue-Retaining Devices (TRDs): These use a suction bulb to hold the tongue forward. Because they do not require jaw movement, they are often a better choice for people with missing teeth or TMJ disorders.
- Soft Palate Lifters: These aim to lift the uvula and soft palate to stop vibrations. However, evidence regarding their effectiveness for OSA is limited and inconsistent.
Custom-Fitted vs. Over-the-Counter Options
You can obtain these devices in two primary ways:
- Custom-Fitted: A dentist or sleep specialist creates these using digital scans or impressions. They offer a precise fit, which generally increases comfort and reduces jaw strain.
- Over-the-Counter (OTC): Often called “boil-and-bite” guards, these are heated and molded at home. They are typically less expensive and are often marketed for snoring rather than medical-grade OSA treatment.
Benefits and Potential Risks
Using these devices can lead to better quality of life, decreased daytime fatigue, and improved blood pressure over several years. They are often more tolerable than CPAP machines; research shows more people meet the recommended four-hour nightly usage mark with a mouth guard than with CPAP.
However, they may not be as effective as CPAP. About one-third of users see no significant improvement, and CPAP generally provides a greater increase in blood oxygen levels.
Possible side effects include:
- Dry mouth or drooling
- Headaches or tooth pain
- Gum irritation
- Changes in bite or tooth position
- TMJ discomfort (which often resolves within 6 to 12 months)
Choosing the Right Device
Before selecting a device, a sleep study is necessary to confirm if you have central sleep apnea, primary snoring, or OSA. For those with moderate or slight OSA, these devices work best.
When evaluating options, consider:
- The Design: Whether you need your jaw moved (MAD) or your tongue held (TRD).
- The Fit: Custom devices typically provide the best results.
- Adjustability: Some custom models allow for small changes to the jaw position over time.
When to See a Doctor
Consult a healthcare provider or a trained dentist to determine if an oral appliance is safe for you. You should seek medical advice if:
- Your partner notices you are still pausing your breath or snoring loudly.
- The device causes significant pain or becomes uncomfortable.
- You have severe OSA, as you may require CPAP or other medical interventions.
- You have loose teeth or severe jaw joint problems.
FAQ
What is the price of mouth guards for sleep apnea?
Costs vary based on the device type, initial exams, and follow-up visits. Generally, two-piece designs are more expensive than one-piece versions.
Is a prescription necessary for sleep apnea mouth guards? Professional-grade appliances need a clinical fitting for better results, though some options are available over-the-counter.
What is the recommended cleaning frequency for your guard?
Most manufacturers suggest cleaning the device daily during your morning routine. Additionally, you should soak and disinfect it weekly using a recommended tablet or solution.
