SnoreRx Mouthpiece Review

Half of all adults snore at least some of the time. For some people, though, it’s a chronic irritant that keeps them and anyone sleeping within earshot from getting a good night’s sleep. Some snorers have obstructive sleep apnea, but even so, it might be easily treatable.

One solution to consider is an anti-snoring mouthpiece. These are effective for most people, come at a modest cost, and are often a better solution than a costly and uncomfortable CPAP mask. This guide will show you the SnoreRx, a highly customizable and adjustable anti-snoring device.

SnoreRx is a Mandibular Adjustment Device (MAD) that is affordable and durable and might be a good solution for your snoring. We prepared this guide to tell you about the mouthpiece, its materials, how it stops snoring, cost, side-effects, customer reviews, and our expert rating of the device.

What is SnoreRx and How Does it Work?

There are two types of over-the-counter anti-snoring devices. Both intend to keep your tongue from obstructing your airway, but they approach the problem differently.

Tongue Retaining Devices (TRD) physically restrain the tongue by pressing it down so it can’t slide into the throat while you’re sleeping on your back.

Mandibular Adjustment Devices (MAD) work by sliding the lower jaw forward and that moves the base of the tongue forward to prevent it from sliding back into the airway.

The SnoreRx anti-snoring device is a MAD. It pushes the jaw forward to keep your airway clear and can be adjusted in tiny increments so that it pushes your mandible enough to keep the throat unobstructed but not so much that it causes ongoing jaw discomfort.

How SnoreRx differs from other anti-snoring mouthpieces

SnoreRx has two primary differentiators from other anti-snoring MADs on the market. The first is advanced customization and the second is durability. When you pay for an appliance to help stop snoring, you want to know that it will perform and last.

Based on our expert examination and customer reviews, the SnoreRx does both quite well. The soft inner portion of the mouthpiece is more customizable than competing “boil and bite” mouthpieces and can be re-boiled and customized to your bite up to three times to get it right.

Also, once you customize the bite pads, the forward movement of the lower jaw can be adjusted incrementally to optimize results and comfort. You can experiment with which setting works best for you and puts a stop to your snoring while minimizing side effects.

Critical Data on Mandibular Advancement Devices

Mandibular Advancement Device (MAD)
Function: MADs push the lower jaw (mandible) forward which pushes the base of the tongue away from the back of the throat where it can obstruct the airway
Sizing: Over-the-counter MADs are self-fitted using a “boil and bite” method while a physician or dentist fits prescription MADs
Adjustment: Many MADs can be adjusted to optimize comfort and performance
Material: MADs are usually plastic, but some may be silicone
Breathing Function: MADs help wearers obtain better nighttime airflow and clear breathing
Side Effects: Pain or stiffness in the jaw, excessive salivation, dry mouth/tongue/throat, tooth discomfort, or bite changes but most ease once you adjust to wearing the MAD
Bruxism aid?: Can help reduce tooth-grinding but it might wear the MAD out faster
Denture-friendly?: MADs are not made to use with dentures. Custom-modified dentures for anti-snoring are an alternative to explore, as is using a TRD
Expected Lifespan: Depending on your sleep habits and the quality of the MAD, you may see 12-24 months of use, but durability varies widely by brand
Average Cost: You can get an OTC MAD for $50-150 or pay up to $1,000 for a custom prescription MAD


Product Specifics

Here’s a quick look at the SnoreRx mouthpiece including info on materials, how it works, and whether it might work to relieve your snoring.


The SnoreRx anti-snoring mouthpiece is a Mandibular Advancement Device (MAD) that pushes your lower jaw forward to alter the position of the tongue and prevent airway blockage and snoring.


SnoreRx uses copolymer plastic. These are the same materials used in athletic mouthguards to protect from mouth and jaw injuries. The outer trays are firmer while the inner pads are softer, and you self-customize to fit your bite.

Sizes available:

The mouthpiece comes in only one size but is highly customizable and adjustable so it will fit most sleepers.


The SnoreRx is fully customizable via a boil and bite tooth impression, and the entire process takes less than five minutes.

Ability to re-adjust:

SnoreRx is adjustable in 1 mm increments and can be re-adjusted at any time to optimize comfort. Once adjusted properly, the device locks in so it shouldn’t fall out of calibration.


MADs, in general, have about a 90% effectiveness rate. SnoreRx produces the same or better results for most sleepers.

Side effects:

Users complain of initial jaw soreness, discomfort, salivation, and dry mouth. The maker recommends wearing the mouthpiece during waking hours to train the jaw to accommodate the MAD.

Ease of breathing:

The mouthpiece is designed with airflow holes and should not obstruct breathing if you mouth breathe while you sleep.

Ease of cleaning:

The cleaning recommended is more arduous than other MADs. SnoreRx advises you brush daily with toothbrush and toothpaste but preferably an ultrasonic cleaner. They also recommend weekly cleaning with a denture tablet.

Denture friendly:

SnoreRx, like other MADs, is not recommended for wear with dentures, bridgework, loose teeth, braces, and other dental appliances.

Bruxism concerns:

The device can help alleviate night grinding, but if you’re an aggressive tooth grinder, this can wear out your SnoreRx faster than expected.


There is no warranty, but a 30-day return window. SnoreRx seems to have an emphatic return policy based on postmark of the return package and do not refund shipping costs.


SnoreRx buyers share that the mouthpiece lasts longer than anticipated and is more durable than competitor MADs, with many buyers getting 20 months of useful life from the device.


SnoreRx sells one mouthpiece for $99 and a set of two for $154. It’s a typical price for a MAD, but it’s a better value than some because of the longer average useful life.

Ease of Breathing: Many airholes for easy airflow Very Good
Ease of Cleaning: More aggressive cleaning regimen than other MADs Good

Fitting the SnoreRx Mouthpiece

The SnoreRx is one of the most customizable MADs on the over-the-counter anti-snoring mouthpiece market. It’s second only to prescription appliances custom-fitted by a dentist. It’s easy to customize SnoreRx and you can re-fit up to three times over its useful life.

You will need these items on-hand to customize your SnoreRx:

  • A small microwave-safe bowl of water
  • Second bowl filled with cool tap water
  • Timer
  • Spoon or tongs

To customize your SnoreRx anti-snoring mouthpiece:

  1. Set SnoreRx to the 3mm baseline setting. Squeeze the top and slide the bottom until the arrow points to the “3” on each side.
  2. Boil water to a full boil in the microwave in the cup/bowl.
  3. Submerge the mouthpiece in hot water for exactly 90 seconds.
  4. Dip SnoreRx out of the hot water with a spoon or tongs.
  5. Dip the device into the second bowl of room temperature water for three seconds.
  6. Bite the mouthpiece and hold the bite for 30 seconds.
  7. Dunk it back into the room temp water for a minute. It’s ready to use!

If you don’t see a clear bite mark impression, you may need to try again. You can repeat this process up to three times to make sure the fit is correct. There’s a custom video on YouTube to help you customize the mouthpiece and another on how to fine-tune it with the adjustment feature.
