This is the answer to the fixed-position problem.

Most $20 snoring mouthpieces lock your jaw in one fixed position. VitalSleep has a special Accu-Adjust System that moves your lower jaw forward in small 1 millimeter steps.

If you snore a little, you may only need a small move. If you snore louder, you can move it a bit more.

You keep adjusting it until you find the spot that works best for you.

Adjustable range: 0-8mm ● Advance or retreat in 1mm steps

We recommend Men's Size for men and Women's Size for women. The Women's Size is about 10% smaller.

If the size you order doesn't fit right, we'll exchange it for the other size free.

Exchange it for the other size free. No restocking fee, and return shipping is covered.

If the first impression just wasn't clean, you can also re-mold the same device. Most fit complaints are a molding issue, not a size issue.

You have 60 nights. If you're not satisfied, return it for a refund under the return policy.

Give it the full adjustment range before you decide. The setting that works is usually a millimeter or two from the one that doesn't.

1 It Stays Put at 3 A.M.

Your teeth are not the same shape as anyone else's.

Hot water, bite down, done in about a minute. It sets to your teeth, which means it stays put when you roll onto your side at 3 a.m. instead of working loose and waking you up.

Available in men’s and women’s sizes.

  • Molds at home in about a minute
  • Holds its shape night after night
  • Two sizes for a more comfortable fit

2 Dial In Your Own Setting

Snoring isn’t one problem with one setting.

The patented Accu-Adjust System moves your lower jaw forward from 0 to 8 mm in 1 mm steps. Turn the screw, sleep on it, change it tomorrow night if you need to. More room in the airway is what helps reduce snoring.

Individual results may vary.

  • Adjusts 0 to 8 mm in 1 mm steps
  • Turn it with the included tool
  • Each step forward opens a little more airway

3 Nothing Standing Between You and Bed

No Dentist. No Prescription. No Waiting.

A dentist-made mouthpiece means appointments, impressions, and a wait. This one arrives at your door and works that night.

  • Ready the day it arrives
  • No prescription or dental visit
  • Rinse, store, repeat

Why So Many Snoring Devices End Up in the Drawer

Why So Many Snoring Devices End Up in the Drawer

Snoring starts when your airway narrows and the soft tissue vibrates.

Most mouthpieces hold your jaw at one fixed setting. That setting is a guess. Too little does nothing. Too much is uncomfortable.

Every jaw needs its own position, measured in millimeters.

Find Your Fit. Fine-Tune Your Comfort. Sleep Quieter.

VitalSleep gives you more control over your comfort and results than a basic anti-snoring mouthpiece.

Mold it at home in minutes for a secure, personalized fit. Then use the patented Accu-Adjust System to gradually move your lower jaw forward until you find the setting that works best for you.

Choose from two available sizes, including a smaller option designed for women. The open design also allows airflow through the mouth as you sleep.

The result: less snoring, more restful sleep, and quieter nights for both of you.

A Dentist-Quality Fit, Without the Dentist

VitalSleep uses a simple boil-and-bite fitting process that lets you mold the mouthpiece to your unique teeth and bite — right at home.

When heated in warm water, the mouthpiece’s thermoplastic material softens so you can bite into it, creating precise dental impressions. Once cooled, it retains that custom shape for a secure and comfortable fit that keeps your airway open during sleep.

This process mimics how dentists create custom sleep devices, but without the $800–$3,000 cost of a professional fitting.

Benefits of a Personalized Fit:

  • Comfortable and easy to wear
  • Reduces pressure on teeth and gums
  • Enhances comfort and breathing effectiveness
  • Easy to re-mold if adjustments are needed

Enjoy the comfort of a dentist-quality fit from home — quickly, easily, and affordably.

PERSONALIZED, ADJUSTABLE COMFORT IN JUST MINUTES

Easy To Use & Comfortable To Wear

Getting a Great Fit Is Easy

Think soft clay, not a bite into an apple.

Gentle pressure gives you a clean mold. Hard biting does the opposite. It squeezes the warm material too thin, and the tray loses its grip on your teeth.

Three things to remember:

  • Press down firmly and evenly, not hard
  • Bite both sides at the same time
  • Hold steady, no grinding or shifting your jaw

You want clear tooth marks with the tray still holding its shape.

Fit not right? Reach out. We'll walk you through it, and if you need a different size, the exchange is free. Every VitalSleep is backed by a one-year unlimited warranty.

Snoring Mouthpiece, Mouth Guard, or Snore Guard: What's the Difference?

People call this device many things: a snoring mouthpiece, a snoring mouthguard, a snore guard, a snore stopper, or an anti-snoring device. These names generally describe a mandibular advancement device that holds your lower jaw slightly forward while you sleep to support airflow and help reduce snoring.

Custom-Fit Snoring Mouthguard for Adults

A snoring mouthguard is worn while you sleep to support your lower jaw and help maintain airflow. This forward jaw position may help reduce the throat vibrations associated with snoring.

A sports mouthguard protects your teeth from impact. A grinding guard creates a barrier between your upper and lower teeth. Neither is designed to hold your lower jaw forward. VitalSleep is designed specifically to help reduce snoring.

What makes VitalSleep different from a generic mouthguard:

  • Heat-moldable material forms around your teeth for a secure, personalized fit
  • Adjustable lower tray lets you control how far your jaw advances in small steps
  • Two available sizes provide separate Men's and Women's fit options
  • Free size exchange if the size you picked is not the right one for you
  • FDA-cleared for snoring reduction, which sports guards and grinding guards are not

No prescription needed. Mold it at home in minutes. Try it for 60 nights with a money-back guarantee.
