What is SnoreRx?

SnoreRx is a snoring mouthpiece that you can use to prevent snoring while you sleep. SnoreRx is a Mandibular Advancement Device (MAD) which means it's a mouthpiece that works by moving the lower jaw forward, preventing the vibration that causes snoring.

What is a snoring mouthpiece?

Snoring mouthpieces, also referred to as "snore guards", "snoring mouth guards", "anti-snoring mouthpieces" and other similar names, are devices which advance the lower jaw to stop snoring.

There are two main types of snoring mouthpieces, Mandibular Advancement Devices (MADs) and Tongue Stabilizing Devices (TSDs). A MAD advances the jaw using the teeth while a TSD advances the jaw with only the tongue. SnoreRx is a MAD because it relies on your teeth to advance your jaw.

Pros And Cons Of SnoreRx

How It Works

How does SnoreRx work?

The SnoreRx snoring mouthguard works by keeping your airway open while you sleep. This is accomplished with an impression of your teeth which is used to keep your jaw in place while you sleep, preventing it from falling back.

You first make an impression of your teeth at home using boiling water (full directions below). After you've made a firm impression of your teeth, you can adjust the position of your jaw by moving the calibration settings on each side of the device.

The firm impression of your teeth and the advancement of your jaw, by using the calibration settings, keep you from snoring. You can adjust the calibration settings on SnoreRx multiple times until your snoring stops.

What Is The Difference Between SnoreRx and SnoreRx Plus?

Snore RX Plussnorerx-plus-mouthpiece

While the original SnoreRx was impressive in its own right, the Plus version brings several improvements, which is definitely a major advantage. The main enhancements include:

  • Flex-Jaw Design: This makes the SnoreRx Plus micro-adjustable to accommodate differing levels of lower jaw advancement among users. The device allows you to fine-tune adjustments in 1 mm increments, ensuring a near-perfect fit irrespective of your needs.
  • Posi-Lock Control: This unique feature simplifies the process of cleaning the device. It remembers how the upper and lower pieces fit together, saving you the hassle of remembering the exact configuration every time you clean it.
  • Thermal-Matrix for Wear Retention: Exclusive to the Plus version, this built-in technology further refines your custom impression and enhances the fit of the mouthpiece to minimize chances of it slipping out.
  • V-Flow Technology: The SnoreRx Plus comes with a generous opening at the front of the unit, allowing easy breathing. Moreover, you can even open your mouth while the device is in.

The SnoreRx Plus is made from comfortable, medical-grade plastic and is BPA-free and non-latex. It is also approved by the U.S. FDA and expected to last 12-18 months before needing replacement.

However, it's important to note that any mouthpiece may potentially affect dental work. If you wear dentures or have a bridge, consult with your dentist before using the SnoreRx Plus. Also, Mandibular Advancement Devices are intended to address a specific type of snoring - caused by soft tissue obstruction. If your snoring has different causes, other remedies may be required.

In conclusion, the SnoreRx Plus is an upgraded version of the original SnoreRx, bringing a host of additional features for a more personalized, comfortable, and effective snoring solution.

SnoreRx was made for men and women, 18 years and older, with simple snoring, that have healthy teeth and gums.

SnoreRx was approved by the FDA for snoring.

How do I know if SnoreRx will work?

SnoreRx is designed to fit comfortably in most mouth sizes. The custom calibration options allow the device to be adjusted to a setting that is comfortable for you.

You can see actual results on this page from a real patient which show its effectiveness.

How do I know if SnoreRx works for while I am asleep?

How wide is the SnoreRx airway?

SnoreRx has an airway opening of 3 millimeters. This is less than some other mouthpieces. The wider the airway opening, the more likely the tongue will stick out of the device which can improve breathing. You cannot stick your tongue through the front of SnoreRx.

What is the length and width of SnoreRx?

SnoreRx is 64mm wide and 51mm in length.

How does SnoreRx compare to other mouthpieces?

When reviewing, what sets SnoreRx apart from other snoring mouthpieces is that it combines multiple fittings methods for maximum comfort and effectiveness.

SnoreRx uses a boil and bite method to make an impression of your teeth and then the position of the upper and lower parts can further be set incrementally.

Many mouthpieces only fit to your teeth using a boil and bite fit but SnoreRx takes this one step further and helps lock in the best position to stop snoring with its re-adjustable calibration settings. These settings allow you to open your airway in a comfortable and effective manner.

SnoreRx vs. ZQuiet

SnoreRx is different than ZQuiet in the following ways:

  • SnoreRx custom molds to your teeth (ZQuiet does not mold to your teeth)
  • SnoreRx can be adjusted incrementally to a specific position (ZQuiet has 2 sizes instead)
  • SnoreRx does not have a hinged design

SnoreRx vs. VitalSleep

SnoreRx differs from VitalSleep in these ways:

  • SnoreRx does not use adjustment tools like VitalSleep to advance the lower jaw, you can adjust SnoreRx using 1mm increments on the side with just your hands
  • SnoreRx has a tighter fit and leaves deep impressions of your teeth in it
  • SnoreRx is more durable than VitalSleep

Patient Results

Actual Patient Results Wearing SnoreRx

A patient who snored wore SnoreRx for three consecutive nights at its factory default setting.

The results, captured using a snoring app, show that the snoring was reduced in duration and intensity each night. The patient's results could have been further improved by adjusting the mouthpiece setting to a number higher than its default setting of 3.

Overall, the patient mentioned mouthpiece was comfortable to wear at night. They mentioned it was a bit bulky but that this did not interrupt their sleep or cause discomfort.

Fitting Process

Step-by-step fitting instructions for SnoreRx (SnoreRx molding instructions)

Note: You should brush your teeth before fitting SnoreRx


  • Microwave (you can use a stove)
  • Sauce pan or teapot (to boil water)
  • Empty glass (for room temperature water)
  • 3 quarts of water (2 for boiling, 1 to cool the mouthpiece)
  • Tongs (or spoon)
  • Timer (a phone or clock will work)
  • The SnoreRx mouthpiece (keep it at its factory setting of 3 during fitting)

Step-by-step fitting instructions:

  1. Boil 2 quarts of water in a microwave or on the stove
  2. Drop SnoreRx into the boiled water for exactly 90 seconds then remove SnoreRx with tongs or spoon
  3. Quickly dip SnoreRx into a glass of tap water, which should be at room temperature, for 3 seconds to remove hot water
  4. Place SnoreRx in your mouth and bite down on it firmly for 30 seconds
  5. Remove SnoreRx from your mouth and put it in a bowl of tap water for 60 seconds to set the impression
  6. Adjust the setting to your bite (the device can be adjusted by 1 millimeter increments up to 6 millimeters)
    • The mouthpiece should default to "3" and this may be enough (most snoring should be reduced with a setting between 3-5mm)
    • Sqeeze the mouthpiece triangles in to disengage the locking mechanism, allowing the upper tray to remove
    • Advance the device by pulling forward on the lower jaw piece (listen for the clicks)

Note: If the device does not have a firm impression, repeat steps 1-5. Also, re-adjust the setting to the level that feels comfortable if needed.

Photos of the fitting process:

Before fitting SnoreRx, you need to bring the water to a boil. Have a bowl of water that's room temperature near by. You can boil the water in the microwave if you know how long it takes to boil, or just use a stove to actually see it boil while it heats.


Next, place the mouthpiece into the hot water using tongs, or some other type of utensil, which you can remove it with. Keep the mouthpiece in the hot water for exactly 90 seconds.

place snorerx into hot water with tongs

After 90 seconds, quickly remove SnoreRx and place it into the bowl of room temperature water to get the hot water off of it before putting it in your mouth. Put the mouthpiece into this water for 3 seconds and then begin fitting it.

What does SnoreRx look like after fitting?

After fitting SnoreRx, you should see clear impressions of your teeth on the upper and lower parts of the mouthpiece.

This is a bottom view of SnoreRx after fitting it:

This is a top, front view of the mouthpiece which shows the impression:

This is a front view of the SnoreRx after making the impression:

front of snorerx after impression

Note: if there is excess material from fitting that extends outside the mouthpiece that is sharp or bothers your gums, you can cut it away.

How much can SnoreRx be adjusted?

Once you have a firm mold of your teeth, you can adjust the lower jaw settings in increments of 1 millimeter. There are 10 increments to adjust the mouthpiece, you can change the increments many times because they are solid parts.

The default factory position of "3" is enough for some people. This position leaves the lower jaw in a less open position but it should still work for most people.

The below photo shows SnoreRx advanced to its maximum position. At this position, the lower jaw is advanced far forward and greatly opens the airway.

SnoreRx adjusted to the max

How do I adjust SnoreRx myself?

  1. Hold your mouthpiece in a reverse ‘C’ position.
  2. Use both of your hands to hold the upper tray in place and use both of your thumbs to push both sides forward.
    • The lower tray will click forward, one notch at a time.
    • Squeezing in both sides of the lower tray simultaneously will disengage the locking mechanism allowing for the upper tray to be moved.

Advancing is best done by pulling forward the lower jaw piece. It’s helpful to try to move one side at a time, one setting at a time. For example, rock the left side back one notch, then rock it back and move the right side back one notch. Make sure that both sides of your device read the same number or millimeter increment. Future adjustments may be made as needed.

What's the best setting to use?

SnoreRx says that most people find success with the factory setting of three (3) millimeters.

If you notice your snoring is still occurring, you would then advance the settings to four (4) millimeters. Each setting should be worn a minimum of 3 to 5 nights prior to adjusting. The idea is to gradually increase the settings until your snoring is reduced or completely eliminated.

It is important that each side of the device always reflects the same setting so that SnoreRx works correctly and that it's comfortable.

Can I re-mold my teeth impression?

Yes, you can re-mold your SnoreRx teeth impression by repeating the fitting steps up to three (3) times. After this, the material becomes too soft and it will not stay in your mouth as well when you wear it.

Does SnoreRx come apart?

SnoreRx designed to remain as one solid unit at all times.

You should not attempt to remove the soft material on the top and bottom from the hard plastic because they are not designed to be removed and will not go back into place if removed.

How long does it take to get used to wearing SnoreRx?

SnoreRx says that you will experience an adjustment period which takes around three to five nights of consistent use.

It is perfectly normal for your jaw, teeth, and gums to feel moderately sore and at first. This discomfort is much like getting used to braces or a retainer for the first time. However, it is not normal to experience severe, sharp, or ongoing pain. If you experience these problems discontinue use immediately and contact your health care professional or dentist.

What if SnoreRx does not work for me?

If you use SnoreRx and it does not work, you should first try adjusting the device to increase the airway opening. There are many settings on the mouthpiece so you can open your airway incrementally each night.

If your teeth impression is not well made, you can re-fitting the device.

One of the most common problems with snoring mouthpieces is user error caused by an improper fit. Make sure you have a firm fit created from a good impression. Also, make sure that you advance the lower jaw as much as you can comfortably bare to ensure your airway is open.

If you have tried the product for two weeks after making the best possible impression and the most advanced position for the device you can tolerate without success, you can return it for a refund.
