Do Dental Guards Help With Sleep Apnea?
Dental guards, specifically mandibular advancement devices (MADs), can indeed help with mild to moderate obstructive sleep apnea by repositioning the jaw to keep the airway open; however, they are not a suitable solution for all cases and require professional evaluation.
Understanding Sleep Apnea and Its Impact
Sleep apnea is a serious sleep disorder characterized by pauses in breathing or shallow breaths during sleep. These interruptions can occur numerous times a night, leading to fragmented sleep and reduced oxygen levels. There are two main types: obstructive sleep apnea (OSA), where the airway becomes blocked, and central sleep apnea (CSA), where the brain fails to signal the muscles to breathe. Our focus here will be on OSA, as dental guards primarily address this type. The long-term consequences of untreated sleep apnea can include:
- High blood pressure
- Heart disease
- Stroke
- Diabetes
- Daytime fatigue
- Increased risk of accidents
The Role of Dental Guards: Mandibular Advancement Devices (MADs)
When discussing dental guards for sleep apnea, we’re typically referring to mandibular advancement devices (MADs). These devices, custom-fitted by a dentist, work by gently pushing the lower jaw forward during sleep. This forward movement helps to:
- Increase the space in the airway.
- Reduce or eliminate the collapse of soft tissues at the back of the throat.
- Alleviate snoring, a common symptom of OSA.
It’s crucial to differentiate MADs from over-the-counter (OTC) boil-and-bite mouthguards, which are often marketed for teeth grinding (bruxism). While OTC guards can protect teeth, they generally lack the adjustability and effectiveness needed to treat sleep apnea.
Are You a Candidate for a Dental Guard for Sleep Apnea?
Do Dental Guards Help With Sleep Apnea? The answer isn’t always a straightforward “yes”. The suitability of a dental guard depends on several factors, including:
- Severity of Sleep Apnea: MADs are most effective for mild to moderate OSA. For severe cases, a CPAP machine (continuous positive airway pressure) is usually the recommended treatment.
- Dental Health: A thorough dental examination is essential to ensure healthy teeth and gums. MADs can potentially exacerbate existing dental problems if not properly fitted and monitored.
- Individual Anatomy: The shape and size of your jaw and airway influence how well a MAD will work.
- Patient Compliance: Successful treatment requires consistent use of the device.
Getting Fitted for a Custom Dental Guard
The process of obtaining a custom-fitted MAD typically involves these steps:
- Consultation with a Dentist or Sleep Specialist: This initial evaluation determines if you’re a suitable candidate and rules out any underlying dental issues. A sleep study might be ordered to confirm the diagnosis and severity of sleep apnea.
- Dental Impressions: Your dentist will take impressions of your upper and lower teeth to create accurate models.
- Device Fabrication: A dental laboratory uses the models to fabricate a custom-fitted MAD.
- Fitting and Adjustments: Your dentist will fit the device and make any necessary adjustments to ensure a comfortable and effective fit. Periodic follow-up appointments are crucial to monitor progress and make further adjustments.
Advantages and Disadvantages of Dental Guards Compared to CPAP
| Feature | Dental Guard (MAD) | CPAP (Continuous Positive Airway Pressure) |
|---|---|---|
| Effectiveness | Highly effective for mild to moderate OSA | Gold standard for all levels of OSA |
| Convenience | More portable and convenient for travel | Less portable and requires a power source |
| Comfort | Some patients find it more comfortable than CPAP | Some patients find it uncomfortable and claustrophobic |
| Compliance | Higher compliance rate in some studies compared to CPAP | Lower compliance rate due to discomfort and inconvenience |
| Side Effects | Jaw pain, dry mouth, excessive salivation, tooth movement | Dry nose, nasal congestion, skin irritation |
| Cost | Typically less expensive than long-term CPAP therapy | Can be more expensive over time due to supplies and maintenance |
Potential Side Effects and How to Manage Them
While MADs are generally safe, potential side effects can occur:
- Jaw pain or temporomandibular joint (TMJ) discomfort: Often resolves with adjustments or temporary cessation of use.
- Dry mouth: Drinking water before bed and using a humidifier can help.
- Excessive salivation: Usually temporary as the mouth adjusts to the device.
- Tooth movement or changes in bite: Rare but possible; regular dental checkups are crucial.
Maintaining Your Dental Guard
Proper care and maintenance are essential for extending the life of your dental guard and preventing bacterial buildup:
- Clean the device daily with a toothbrush and mild soap or a specialized dental appliance cleaner.
- Store the device in a clean, dry case when not in use.
- Bring the device to your regular dental checkups for inspection.
Alternatives to Dental Guards and CPAP
While MADs and CPAP are the most common treatments for OSA, other options exist:
- Positional Therapy: Avoiding sleeping on your back.
- Weight Loss: Obesity is a significant risk factor for OSA.
- Surgery: In some cases, surgery to remove excess tissue in the throat or correct jaw deformities may be an option.
- Tongue Retaining Devices: These devices hold the tongue forward to prevent it from blocking the airway.

Frequently Asked Questions (FAQs)
How do I know if I have sleep apnea?
Common symptoms include loud snoring, gasping or choking during sleep, daytime fatigue, morning headaches, difficulty concentrating, and irritability. A sleep study, typically conducted at a sleep center or at home, is necessary to confirm a diagnosis.
Are over-the-counter dental guards effective for sleep apnea?
While OTC dental guards might provide some relief from snoring, they are not recommended for treating sleep apnea. They lack the precision and adjustability of custom-fitted MADs and may even worsen the condition.
How long will a dental guard last?
The lifespan of a dental guard varies depending on the material, usage, and maintenance. With proper care, a custom-fitted MAD can last several years. However, it’s essential to have it checked regularly by your dentist to ensure it’s still functioning correctly.
What are the risks of using a dental guard for sleep apnea?
Potential risks include jaw pain, tooth movement, changes in bite, dry mouth, and excessive salivation. These side effects are generally manageable with adjustments to the device and proper dental care.
Can I still wear a dental guard if I have dentures?
In some cases, MADs can be adapted for use with dentures. Your dentist will need to assess your specific situation to determine if it’s a viable option.
How often should I clean my dental guard?
It’s recommended to clean your dental guard every day to remove bacteria and prevent odor buildup. Use a soft toothbrush and mild soap or a specialized dental appliance cleaner.
What should I do if my dental guard is causing pain?
Contact your dentist immediately if you experience persistent pain or discomfort. They can adjust the device or recommend alternative solutions.
How much does a custom dental guard cost?
The cost of a custom-fitted MAD can vary depending on the dentist, the type of device, and your insurance coverage. It typically ranges from several hundred to several thousand dollars.
Will a dental guard completely cure my sleep apnea?
Do Dental Guards Help With Sleep Apnea? While MADs can effectively reduce the severity of sleep apnea, they may not completely cure the condition. They are most effective for mild to moderate cases. Regular monitoring and follow-up appointments are essential.
Are there any lifestyle changes that can help with sleep apnea in addition to using a dental guard?
Yes, lifestyle changes such as weight loss, avoiding alcohol and sedatives before bed, and sleeping on your side can significantly improve sleep apnea symptoms.
Can I wear a dental guard if I have temporomandibular joint (TMJ) disorder?
If you have TMJ disorder, it’s crucial to discuss this with your dentist before getting a MAD. In some cases, a dental guard may worsen TMJ symptoms. Your dentist can assess your situation and recommend the most appropriate treatment option.
Where can I find a dentist who specializes in dental guards for sleep apnea?
Look for dentists with expertise in sleep medicine or craniofacial pain. You can also ask your primary care physician or sleep specialist for a referral. Ensure the dentist has experience in fitting and adjusting MADs for sleep apnea.
