How Do Anti Snoring Mouthpieces Work?

Snoring occurs when the tissues behind the throat relax and narrow the airway during sleep. As air passes through while breathing, these tissues vibrate and result in the familiar snoring sound. The narrower the airway, the more intense the snore becomes.

Snoring mouthpieces are designed to stop snoring by moving the lower jaw forward to maintain an open airway during sleep. Unrestricted airflow reduces these tissue vibration sounds and promotes a quiet night’s rest. When used correctly, snoring mouthpieces improves breathing and reduces irritating snoring. Less snoring promotes a better night’s sleep, the elimination of daytime drowsiness, and restoration of energy.

Features of an Anti Snoring Mouthpiece

There is a variety of snoring mouthpieces that offer unique features and functionality.

Custom Impression

Some snoring mouthpieces use the ‘boil and bite’ process to create a custom fit to your teeth. This method involves heating the device to soften the material and then biting down to create the impression. Some devices do not offer a custom impression, while others such as custom oral appliances take a precise impression with a clear acrylic liner.

Oral Appliances and Snoring Mouthguards

Custom oral appliances are often prescribed by dentists and sleep physicians and are manufactured in a dental lab. In contrast, snoring mouth guards are often considered an affordable alternative to oral appliances and are classified as either a Mandibular Advancement Device (MAD) and a Tongue Retaining Device (TSD).

Mandibular Advancement Devices (MAD) and Tongue Retaining Devices (TSD)

Mandibular advancement devices often resemble a sports mouthguard and are designed to extend the user’s lower jaw forward to open the airway. Tongue Retaining Devices look similar to a pacifier and work by holding both the tongue and jaw forward. Learn more about the differences between MADs and TSDs.


Adjustable snoring mouthpieces are designed to adjust how far the lower jaw is extended. Because some users may require more extension than others, adjustable snoring mouthpieces allow the user to select a custom setting that is most comfortable and effective for them.

SnoreRx is an Anti Snoring Mouthpiece that Works

SnoreRx is an anti snoring mouthpiece that allows the user to calibrate their device to a custom setting at any time in 1-millimeter increments to achieve a more effective setting.

If you notice your snoring is still occurring after wearing SnoreRx for a few nights, you will need to adjust the device an extra millimeter forward. Each setting should be worn at least three to five nights before adjusting to a higher setting.
