Zyppah Mouthpiece Review

Anti-snoring mouthpieces can help many snorers sleep more quietly. In this review, we’ll consider the Zyppah mouthpiece review. Data from an NIH sleep study found that 44% of men and 28% of women are “habitual snorers.” A relatively small percentage snore because of obstructive sleep apnea.

Snoring is noise made when inhaling while sleeping and the structures of the upper airway vibrate. Snoring is not an illness but can be a symptom of an underlying ailment. There are five types of snoring:

  • Nose – Collapsing nostrils or blocked passages can lead to mouth breathing and snoring
  • Mouth – Open mouth posture and a relaxed jaw can lead to snoring sounds
  • Tongue – When the tongue obstructs the airway at the back of the mouth, noise results  
  • Palatal flutterer – If the soft palate and uvula vibrate, there may be sleep sounds
  • Multifactorial – A combination of these factors can lead to snoring

Anti-snoring mouthpieces can be over-the-counter or prescribed by a physician, and they work to correct issues associated with tongue, mouth, and multifactorial snoring. Many snorers have positive outcomes from using a mouthpiece.

This anti-snoring mouthpiece review looks at Zyppah, a patented device that’s unique in the sleep device market. We’ll tell you the materials in the device, how it works, how much it costs, who it can help, customer reviews, and our rating for the device.

What is Zyppah and How Does it Work?

There are two types of anti-snoring mouthpieces to help snorers:

  • Mandibular Advancement Devices (MAD) stabilize your jaw and keep your tongue and soft tissue from impeding breathing.
  • Tongue Retaining Device (TRD) or a Tongue Stabilizing Device (TSD) helps pull your tongue down so it can’t fall back into your throat.

The Zyppah anti-snoring mouthpiece is a Mandibular Advancement Device (MAD). This type of device prevents snoring when you’re sleeping on your back by preventing the back of your tongue from obstructing your airway. It can help tongue and multifactorial snorers.

The word “mandibular” refers to the mandible (i.e., your jawbone). These devices put gentle pressure on the jawbone and push them forward slightly. Because the tongue muscle is attached to the lower jaw, it follows along and moves forward too, preventing it from falling back into the airway.

How Zyppah differs from other anti-snoring mouthpieces

There are many similar MADs on the market to help with snoring. Zyppah is different because of its patented tongue elastic. The body of the mouthpiece is like other MADs, but at the back of the device, there’s a strip of elastic, kind of like a rubber band, that forces your tongue to stay put.

The device is a “hybrid” appliance because it’s a MAD with a TRD element. The mouthpiece pushes the jaw forward, and the elastic is a secondary measure against tongue movement. It doesn’t function like a traditional TRD which is designed more like a pacifier.

Critical Data on Mandibular Advancement Devices

Mandibular Advancement Device (MAD)
Function: Moves the mandible (lower jaw) forward to keep the airway clear and prevent tongue movement
Sizing: The device can be custom-fitted by a physician or self-fitted by the “boil and bite” method
Adjustment: Some MADs are adjustable by increments depending on the design of the device
Material: MADs can be plastic or silicone resin
Breathing Function: Most MADs help wearers breathe more freely through their mouth
Side Effects: Masticatory muscle pain (jaw discomfort or stiffness), hypersalivation (excessive drooling), mucosal dryness (dry mouth), tooth discomfort or loose teeth (for those with underlying dental issues), occlusion changes (disruption of your bite)
Bruxism aid?: May alleviate or reduce sleep bruxism (teeth-grinding)
Denture-friendly?: No! MADs won’t work with dentures, but there is research on modified dentures that serve as a MAD. Usually, TRDs are best.
Expected Lifespan: One to two years is typical depending on materials, usage, etc.
Average Cost: $50-150 (over the counter) $500-1,000 (custom made by a dentist)

Product Specifics

Here’s a look at Zyppah mouthpiece construction, how it performs, and what to expect if you buy this product for your snoring issues. It comes in five colors with the default as black and green.


Zyppah is a Mandibular Advancement Device (MAD) with a TRD component so it’s technically a hybrid appliance.


The material in the main device is an FDA-cleared plastic that’s non-toxic, latex-free, and BPA free. The TRD component is soft rubber.

Sizes available:

This hybrid device is one-size-fits-most and should fit in most mouths. Mouths are similar in size in adults, although bites differ greatly. It’s also slightly smaller than some other over-the-counter anti-snoring mouthpieces.


The Zyppah is “boil and bite.” You place it in hot water, then into your mouth, and it molds to your bite. If you have any issues, you can re-heat and bite again to tweak it. Some buyers report adjusting it up to three times with no issues.

Ability to re-adjust:

None. Zyppah does not recommend trying to adjust its device and doesn’t offer an adjustment mechanism. However, you can re-bite it (see above) and see if that helps.


The device seems to help a wide array of people correct their snoring issues and, in many cases, stops 100% of snoring very rapidly. Buyer reviews are largely enthusiastic.

Side effects:

Some buyers report some initial jaw soreness and excessive salivation that diminish over time. Some report tongue discomfort from the elastic band.

Ease of breathing:

Users have no complaints about breathing issues since it keeps your jaw in the correct position and prevents tongue obstruction plus has an open airflow design.

Ease of cleaning:

The company recommends weekly cleaning using a denture tablet like Efferdent with a quick 5-10 minutes soak. This should help with lifespan and reduce bacteria.

Denture friendly:

Zyppah isn’t recommended if you have loose crowns or teeth, or bridge work and should not be used with dentures.

Bruxism concerns:

It’s not specifically designed to help bruxism, but does because it’s a barrier between your jaws. Those that grind intensely might see a shorter lifespan with the product.


The company offers a 90-day return or replacement warranty. Some customers report issues returning the product. Many competitors only offer a 30-day warranty.


Few over-the-counter anti-snoring mouthpieces have lengthy lifespans. You can expect this one to last from nine to 12 months, but it can vary widely.


Zyppah lists a regular retail price of $125.85 but is selling the product at $99.95. This is typical for a quality anti-snoring mouthpiece.

Fitting the Zyppah Mouthpiece

First, gather the materials you need including:

  • Mirror (ideally bathroom mirror, not handheld)
  • Fork or spoon (plastic or metal)
  • Bowl of water, just under boiling temperature (200o F)
  • Paper towels
  • Timer

Once you get your Zyppah anti-snoring mouthpiece, you must customize it before you can use it. It is an easy 10-step process:

  1. Take the Zyppah mouthpiece out of its protective case.
  2. Drop the mouthpiece into the hot water for 30 seconds.
  3. Use a spoon or fork to hold it in a completely submerged position.
  4. Lift it out of the water using the utensil (not your fingers!) by the elastic piece.
  5. Hold it by the front side or elastic and slide it into your mouth.
  6. The side with the full brand name on it is the bottom piece.
  7. Hold it against bottom teeth for a few seconds to secure it.
  8. Slide jaw forward and bite down into the mouthpiece with upper and lower teeth.
  9. Use the mirror to make sure you’re biting correctly – hold for 10 seconds.
  10. Remove and rinse in cool water to “set” the mouthpiece.

After that, you’re ready to use it. There are no adjustments to the mouthpiece, so it’s important to do this part correctly. The brand offers a YouTube video by the designer to show you how to customize it to fit your bite.

What Do Customers Think of Zyppah?

It is the only hybrid mouthpiece on the market with the functionality of a MAD and the added benefit of a TRD element. Most buyers have positive comments about the mouthpiece and its performance, but as with any product, there is also some criticism.

A few buyers complain of some issues when trying to return the Zyppah if they decide not to keep it. The Better Business Bureau rates them at a B+, and they have no open complaints.

Common feedback from customer reviews include:

  • Immediate relief of snoring for many users
  • Adjustment period is about two weeks
