How SnoreRx Works: Fitting, Adjustment and Care

Last updated: October 9, 2026 • By the SnoreRx Guide editorial team • Educational content

This page explains the mechanism behind SnoreRx, how to mold it, how to set the advancement and how to look after it. It is a summary. The instruction leaflet in the box is the authority for exact heating times.

Why People Snore

During sleep the muscles that hold the jaw and tongue relax. In many people the lower jaw drops back, the tongue follows, and the space behind it narrows. Air moving through that narrow space makes the soft palate and surrounding tissue vibrate. The brand describes this as the root cause that SnoreRx targets.

What a Mandibular Advancement Device Does

A mandibular advancement device holds the lower jaw (the mandible) a few millimeters forward. Because the tongue is attached to the lower jaw, it moves forward too, and the airway behind it opens up. The brand says this widens the airway, reduces tissue vibration and silences snoring.

The Custom Fit: Thermal Matrix Material

The inner lining softens in hot water and records the shape of your teeth when you bite into it. Once cooled it holds that impression. The brand describes it as dental lab quality material that provides fit, retention, comfort and support.

Molding steps in outline

  1. Heat water separately and pour it into a cup or bowl. The manufacturer warns not to heat the device in a pan on the stovetop, because that can damage it.
  2. Submerge the mouthpiece for the time stated in the leaflet.
  3. Let excess water drip off, place it in your mouth and bite down firmly, pressing the material against your teeth.
  4. Cool it in cold water to set the impression.

If the fit feels loose, published reviews say the molding can be repeated. Check the leaflet for how many times.

The Adjustment: 1 mm at a Time

StageSettingWhat to do
Nights 1 to 51 mm (factory setting)Get used to wearing it. Check whether snoring has reduced.
Still snoringMove to 2 mmWear for at least three to five nights before judging.
Repeat as needed3 mm to 5 mmThe manufacturer says most people settle in this range.
Furthest comfortable settingUp to 6 mm, per published reviewsIf you still snore, contact the company before your 30 nights end.

The aim is the lowest setting that works, not the highest one you can tolerate.

Breathing, Talking and Drinking

There is an opening at the front between the trays, so you can breathe through your mouth if your nose is congested. The official offer page says the design lets you talk or drink water without removing it.

Materials

Published reviews describe a medical-grade plastic body that is BPA-free and latex-free, with no metal, screws or springs. The brand states it is made in California.

Cleaning and Care

  • Rinse it every morning and let it air dry.
  • Clean it with a soft toothbrush and cool water or a cleaner intended for oral appliances.
  • Do not use hot water after molding, as heat can distort the impression.
  • Store it dry in its case, away from pets and direct sunlight.
  • Replace it when the fit loosens or the material shows wear.

Standard vs. Plus

On the manufacturer's own site there are two models. The Plus adds a hinge that allows more natural jaw movement and can be taken apart for cleaning. The official offer page does not specify a model.

Frequently Asked Questions

How does SnoreRx work?

It holds the lower jaw slightly forward during sleep, which the brand says widens the airway and reduces the tissue vibration that causes snoring.

How far can SnoreRx be adjusted?

In 1 mm increments. Published reviews give a maximum of 6 mm, and the manufacturer says most people settle between 3 mm and 5 mm.

Can I remold SnoreRx?

Published reviews say the molding can be repeated if the first fit is loose. Check the instruction leaflet for the limit.

Can I breathe through my mouth with SnoreRx?

Yes. There is an opening between the trays that allows mouth breathing.

How do I clean SnoreRx?

Rinse it each morning, brush it gently with cool water, and store it dry. Avoid hot water after molding.
