7+ Best Dental Appliance for Sleep Apnea

Dental Appliance for Sleep Apnea

For those patients with sleep apnea who find that CPAP masks do not work for them, is too uncomfortable or burdensome, or are just looking for a different sleep apnea treatment option, there are a couple of main alternatives: surgery or dental appliances.

For this review, I carefully researched the many options out there to find the best dental appliance for sleep apnea.


Dental Appliance for Sleep Apnea

The standard treatment for sleep apnea (specifically obstructive sleep apnea [OSA]), is CPAP.

CPAP involves the use of pressurized air that is produced by a CPAP machine and conducted through tubing to a CPAP mask that covers the nostrils and/or mouth.

The pressurized air that is delivered through the airways acts to keep the airways from collapsing during sleep, allowing for the adequate flow of oxygen through the body.

Some patients may find CPAP to be intolerable—namely, having to wear a mask at night can be uncomfortable and cumbersome.

Having to maintain a regular cleaning schedule for keeping CPAP equipment clean can also be a time-consuming burden.

Furthermore, CPAP is most effective when used every night, which means that if you travel, you have to remember to take all of your necessary equipment (CPAP machine, tubing, mask, water chamber, cleaning supplies, etc.) with you.

Surgery is one common alternative treatment to CPAP for sleep apnea patients, but for reasons such as the level of invasiveness of the procedure, required time for recovery, or cost, surgery is not preferable for some patients.

Dental Appliance for Sleep Apnea

This brings me to the second alternative option to CPAP: the sleep apnea dental (or also called oral) appliance.

The sleep apnea oral appliance is generally recommended for patients with mild to moderate OSA.

These appliances are customized to fit into your mouth the same way a mouth guard or retainer would.

They act to support the jaw in such a way to help maintain an open airway and allow for the flow of air and oxygen.

Some main advantages of the sleep apnea oral appliance are:

Sleep apnea patients are encouraged to go to a dentist, who can write a prescription for an oral appliance.

The dentist conducts fittings and obtains impressions of the teeth and sends the models to dental lab where the oral appliance is custom made.

However, for those that need an appliance quick or “over-the-counter,” they can also be bought online.

Here, I recommend the best dental appliance for sleep apnea that can be purchased over-the-counter.

My Pick: The IntelliGuard Pro Mouthpiece Night guard

Tranquility PRO 2.0 Anti-Snoring Mouth Guard – Adjustable Mouthpiece – Night Time Teeth Mouthguard & Sleeping Bite Guard for Bruxism and Stop Snoring – Custom Molding & Adjustability
  • Custom Molded Design: Achieve a personalized fit by molding the mouthguard to your teeth with a simple boiling water process.
  • Adjustable Fit: Fine-tune your comfort and effectiveness with millimeter increment adjustments, allowing for precise positioning of the bottom jaw forward for best results.
  • Effective Solution: Designed to target the root cause by gently repositioning the jaw, promoting better airflow and reducing disturbances.
  • Comfortable Wear: Crafted from high-quality, soft materials for optimal comfort during sleep, ensuring a restful night for both you and your partner.
  • Easy to Use: Simple instructions make the fitting process hassle-free, allowing you to enjoy the benefits of a customized anti-snoring mouthguard with minimal effort.

The IntelliGuard Pro Mouthpiece Adjustable Night Guard Bruxism Sleep Aid is my recommendation for an over-the-counter oral appliance for sleep apnea.

The key function of the IntelliGuard Pro is that it repositions the mouth to open the airway. It is excellent for many purposes:

  • Sleep apnea
  • Snoring
  • Bruxism (teeth grinding and jaw clenching)

It is adjustable for a wide variety of mouth sizes, as it fits mouths that range from 2 to 5 inches wide and features 10 possible incremental, 1 millimeter adjustments.

The measurements on the oral appliance are clear so that you can easily calibrate it to your preferred setting for the best fit.

Furthermore, it can “automold” to your bite, so it can form precisely to the shape of your mouth.

All you have to do is boil it in water to make it moldable and bite down onto the mouthpiece to customize it to your bite.

It should be noted, however, that the IntelliGuard Pro is not recommended for those with small mouths.

This new design also features precision lock technology. This means that the lock does not slip and is held in place at your preferred setting while you wear it at night.

Users with sleep apnea report positive feedback on the IntelliGuard Pro and it appears to do an excellent job with reducing sleep apnea symptoms. Specifically, they say that it:

  • Helps them sleep much better
  • No interrupted deep sleep
  • Improves mood the following day
  • Fits very well
  • Does not fall out at night
  • Stops snoring
  • Is simple and inexpensive
  • Takes some time to get used to but works well and is worth it
