What You Need to Know about Oral Appliances for Snoring and Sleep Apnea
Snoring is often a sign of life-threatening sleep apnea. Oral appliances for the treatment of obstructive sleep apnea (OSA) are NOT available over-the-counter in the United States. They are only FDA approved and available through a qualified dentist once a physician has made an obstructive sleep apnea diagnosis.
How Do You Know if You Have Sleep Apnea?
There are three types of sleep apnea, all considered serious sleep disorders:
Central sleep apnea: CSA is resulted when the lungs don’t receive a command from the brain that tells them to breathe
Obstructive sleep apnea: OSA is the result of an obstruction in the upper airway
Complex sleep apnea / Mixed sleep apnea: A combination of central and obstructive apneic events
If you have central sleep apnea or complex sleep apnea, using an oral device could cause severe adverse health effects, including death. Whether or not you think you have sleep apnea, getting a sleep study is highly recommended before using a snoring mouthpiece, and can often be done in the comfort of your own home. If your sleep study results show an apnea hypopnea index (AHI) not indicative of sleep apnea, a dentist can still provide a custom mouthpiece to help you stop snoring.
Why Choose a Custom Oral Appliance?
The American Academy of Sleep Medicine says so: Oral appliances should be fitted by qualified dental personnel who are trained and experienced in the overall care of oral health, the temporomandibular joint, dental occlusion and associated oral structures. (3)
It may be more than snoring!: Only a custom appliance can treat obstructive sleep apnea. In a 2008 study comparing the efficacy of prefabricated anti-snoring devices with custom-made oral appliances, AHI was only reduced with the custom-made oral appliance.(2)
Comfort and effectiveness: In the same 2008 study, the custom oral appliance reduced snoring to a greater extent. The initial success rate with the custom-made oral appliance was 100% higher than with the pre-fabricated device. Total failure rate with the pre-fabricated device was 69%, and the majority (63%) of these were subsequently treated successfully with the custom-made device. At the end of the study, 82% of the patients preferred the custom-made device, and 9% had no preference. (2)
Health Risks and Side Effects: Snoring mouthpieces or dental night guards may help you stop snoring, but potential side effects such as TMJ disorder, worsened sleep apnea, silent apnea, bruxism and shifting of the tooth position may outweigh the benefits of not snoring. Grinding night guards have been shown to increase OSA by as much as 50%. They also increase teeth grinding in sleep apnea patients.
Potential Side Effects of Oral Appliances
Finding a qualified dentist, trained in treating snoring, sleep apnea and TMJ disorder, to monitor your care is the best way to minimize or avoid complications such as:
Sleep Apnea without Snoring (Silent Apnea): You can still have sleep apnea without snoring. By reducing or eliminating the snoring sounds before a sleep study has been done to determine if sleep apnea is present, you could be masking the symptoms but not the disease. This is sometimes referred to as silent apnea. It would be like disconnecting the fire alarm and going back to sleep instead of addressing the fire itself!
Temporomandibular joint (TMJ) disorder: Appliances hold the jaw in a forward position, which could lead to shifting of tooth position and pain in the joints. TMJ disorders can cause jaw joint, ear, and tooth pain and can be caused by misaligned bite, bruxism, cartilage wear-and-tear and joint dislocation. Common consequences of living with the debilitating disease include missed time from work, school, family and loved ones. While choosing an over the counter or seen on TV anti-snoring device may seem easier than seeing your dentist for a custom fitted oral appliance, choosing a dental professional trained in recognizing symptoms of TMJ disorders to monitor your treatment could prevent a lifetime of pain.
Sleep Bruxism: Bruxism means grinding your teeth. It is common not to realize you are grinding your teeth while sleeping. Bruxism may cause TMJ disorders, muscle pain, tooth sensitivity or worn teeth. In some cases, the pressure to the TMJ from constant grinding of teeth leads to ligament injuries, which might cause the disc to dislocate. Sore jaw muscles when waking is an indication that you are grinding your teeth in your sleep.
In fact, oralfacial pain is reported by 66-84% of sleep bruxism patients (1). Research has shown strong links between bruxism and obstructive sleep apnea. Many nightguards for teeth grinding solve the problem of tooth wear and tear, but could actually cause you to grind your teeth more, and do not treat underlying medical conditions or prevent damage to the facial joints and muscles. A qualified dentist involved in monitoring your treatment and adjusting the positioning of the sleep appliance can detect bruxism before too much damage is caused and develop an appropriate treatment plan.
Tooth movement and bite changes: problems like shifting of tooth position may occur
Tooth and gum pain: Pain may also occur within the teeth and gums if the appliance presses firmly against the gum tissue. Your device should be properly fitted by a qualified dentist to reduce this risk.
Dry mouth: Once the oral appliance is in place, mouth dryness may occur overnight. This is more likely if you have nasal congestion or difficulty breathing through your nose (often related to allergies, a deviated nasal septum, or enlargement of the turbinates). If the appliance is large enough, it may not allow your lips to close over it. As a result, parted lips may lead to dryness of the mouth or tongue as breathing occurs.
Oral Appliance Costs Considerations
While over the counter boil and bite mouthpieces may appear to be a cheaper and easier snoring solution, you get what you pay for. The cost of TMJ treatment or much worse, the cost of treatment of untreated sleep apnea health consequences such as heart disease, may exceed the savings from choosing a non-custom snoring mouthpiece. In addition, an oral appliance may be covered by your medical insurance if provided by a dentist who is trained in dental sleep medicine and whose office is experienced in documenting medical necessity and billing medical insurance for oral appliance therapy. Medical insurance does not cover over the counter snoring mouthpieces.
Be willing and able to work closely with physicians and other health care professionals
Have appropriate knowledge of sleep medicine as well as jaw joint function
Have adequate training/education in oral appliance therapy. Ask about Certificates of Attendance from continuing education courses taken
Be able to treat effectively with different appliance types
Have experience with medical insurance reimbursement and documenting medical necessity
Have a solid relationships with local sleep labs and sleep physicians
Have a team approach with other healthcare professionals
Have a proven follow-up system to ensure healthy results long-term
Have an in-depth knowledge of oral appliance research
Provide statement of informed consent, explaining all possible contraindications and potential side effects
Realize that oral appliance therapy is not always the most beneficial treatment and should suggest alternate therapeutic modalities (CPAP, surgery) when appropriate

What causes snoring? At least 30% of adults snore on a regular basis,
but that doesn’t mean snoring is normal. Airway blockage is the root cause
of all snoring problems. Learn when and why you should be worried about snoring.
Sleep Apnea Symptoms
Drowsy during the day? Excessive daytime sleepiness, snoring, gasping during sleep,
morning headaches, night sweats are signs of obstructive sleep apnea.
Learn more about the symptoms of sleep apnea.
Oral Appliance Therapy
How does a custom mouthpiece stop snoring? Tongue retaining devices and mandibular
repositioning devices can prevent collapse of the tongue and soft tissues in the throat
during sleep. Learn how these dental devices stop snoring.
Why see a Dentist?
Why are anti-snoring mouthpieces risky? Mouthpieces can cause tooth movement,
TMJ and bruxism. They can also stop snoring without treating sleep apnea.
