Bottom line: It’s a tie on our scorecards (8.8 each), so price and guarantee decide it: SnoreRx costs half as much ($59.99 vs $119.95), but VitalSleep has the longer 60-night guarantee and comes in two sizes, so it is the better pick if those matter most to you.
Short answer: SnoreRx and VitalSleep are the two best-known adjustable boil-and-bite mouthpieces, and they do the same job in nearly the same way: both mold to your teeth and move your lower jaw forward in 1 mm steps. SnoreRx costs half as much ($59.99 vs $119.95). VitalSleep earns its higher price with a second, smaller size, a 60-night guarantee instead of 30, and a year of free replacements. Most people with a normal-sized mouth should start with SnoreRx. Pick VitalSleep if you have a small mouth, grind your teeth, or want the longer safety net.
How we tested: We bought and tested both SnoreRx and VitalSleep ourselves; our hands-on notes and video reviews are below.

Quick Verdict
- Choose SnoreRx if you want calibrated 1 mm adjustment at the lowest price, have an average-sized mouth, and are comfortable deciding within 30 nights.
- Choose VitalSleep if you need a smaller device, you grind your teeth and will wear through trays (free replacements for a year), or you want 60 nights to find your setting.
- Choose neither if you have dentures, loose teeth, gum disease or TMJ problems, or if your snoring comes with gasping or pauses in breathing (see a doctor first).
- Our hands-on tests: both reduced our tester’s snoring. SnoreRx gave deeper, firmer tooth impressions; VitalSleep has the wider front opening (about 6 mm vs 3 mm).

What They Have in Common
Both are mandibular advancement devices. They grip your upper and lower teeth and hold the lower jaw a few millimeters forward, which pulls the tongue forward and keeps the airway behind it more open (see how snoring mouthpieces work). Both use a heat-moldable lining that you press your teeth into, so neither is a generic one-shape tray. Neither has a hinge, so your mouth stays in one position all night. Both have an opening at the front that allows some mouth breathing. And both are FDA-cleared only to reduce snoring, not to treat sleep apnea.
Most importantly, both let you change the jaw position after fitting, one millimeter at a time. That is the feature that separates them from cheaper fixed-position mouthpieces. The right amount of advancement differs from person to person. Too little does nothing, and too much makes your jaw sore.
Adjustment: Clicks vs Screws
SnoreRx uses a squeeze-and-slide mechanism. You press the two “SQUEEZE” points on the upper tray, slide the lower tray to the next number and let go, and it clicks into place. It ships at 1 mm. The booklet says to wear each setting for three to five nights, and that most people settle between 3 and 5 mm. You can change it by hand in seconds with no tools.
VitalSleep uses its “Accu-Adjust” system. A screw on each side moves the lower tray forward when you turn it clockwise with the included tool, and graduation marks show the position. The maker says to sleep at the starting position for the first few nights before advancing, then to move in small steps. The two screws have to be set to the same mark, or the device feels crooked. The maker calls uneven screws the most common fitting mistake.
In practice both get you to the same place. SnoreRx is quicker to adjust. VitalSleep’s screws give finer control of each side, but that also means more room for error. More on technique in how to adjust a snoring mouthpiece.
Winner: tie. Both offer the 1 mm control that matters.
Fit and Sizing
This is VitalSleep’s clearest advantage. SnoreRx comes in one size, and its most common complaint is that it feels bulky. VitalSleep comes in a men’s (standard) size and a women’s size with an arch about 10% smaller. The maker publishes the dimensions: 67.5 × 50.1 × 21.4 mm for the standard and 61.1 × 47.7 × 23.9 mm for the small. It also exchanges sizes for free. If you have a small mouth or a narrow jaw, that choice matters (see best snoring mouthpiece for small mouths).
The fitting steps differ a little. SnoreRx is precise about its method: microwave-boiled water (not a stovetop pan), exactly 60 seconds, bite for 30 seconds, then 5 minutes in cool water to set. You get two attempts. VitalSleep calls for 45 seconds in hot water and 3 seconds in cold, then an even, gentle bite. It can be re-molded, and the maker sends a free replacement if the fit goes wrong. With either device, a shallow impression is the main reason it falls out at night. Our fitting guide has tips.
Winner: VitalSleep, for the second size and more forgiving fitting support.
Comfort
Our scorecards rate both 8.5 out of 10 for comfort, and the complaints are similar. In the first week or two you can expect morning jaw or tooth soreness, extra saliva, and a bite that feels “off” for a short while after you take the device out. Both makers list these effects in their warnings. The fixes are the same too: start at the lowest setting, advance slowly, and step back one setting if your jaw aches. Pain that lasts or a bite that doesn’t return to normal means stop and see a dentist (see jaw pain from a snoring mouthpiece).
Neither device lets you open your mouth freely. If that locked-in feeling is what you’re worried about, look at the hinged SnoreRx Plus instead.
Winner: tie, unless your mouth is small, in which case VitalSleep’s smaller size tips it.
Price, Guarantee and Long-Term Cost
SnoreRx is $59.99, or two for $99.99. VitalSleep is $119.95. On day one, SnoreRx is clearly cheaper.
Over a year the gap can narrow. Boil-and-bite mouthpieces wear out. VitalSleep’s maker says about a year of normal use, and SnoreRx’s maker says around 6 to 11 months. Heavy teeth grinders wear through them faster. VitalSleep replaces the device free for the first year, and the maker says there’s no limit on the number of replacements. SnoreRx has no advertised warranty, so a grinder might buy the two-pack instead.
The trial windows also differ: 30 nights for SnoreRx and 60 nights from delivery for VitalSleep. Both apply only to orders placed on the maker’s own website. SnoreRx refunds the product price but not shipping. VitalSleep covers U.S. return shipping. If you tend to need a few weeks to get used to a mouthpiece, the extra 30 nights are worth having.
Winner: SnoreRx on price; VitalSleep on guarantee and warranty.
Who Should Buy SnoreRx?
- Adults with healthy natural teeth and an average-sized mouth who want fine adjustment for the least money.
- People who want quick, tool-free adjustments.
- Couples or travelers who’d use the two-for-$99.99 pack.
Full details: SnoreRx review and SnoreRx complaints and fixes.
Who Should Buy VitalSleep?
- People with smaller mouths or narrow jaws, including many women, who find one-size trays too big.
- Teeth grinders who expect to wear through a device within the year.
- Anyone who wants 60 nights to find the right setting.
Full details: VitalSleep review.
What About SnoreRx Plus?
SnoreRx Plus ($99.99) keeps the same 1 mm adjustment and boil-and-bite fit as SnoreRx but adds a hinge, so your jaw can open and close during the night, and it comes apart into three trays for easier cleaning. It’s still $20 cheaper than VitalSleep. If neither rigid device appeals to you, compare it in SnoreRx Plus vs VitalSleep or SnoreRx vs SnoreRx Plus.
Our Hands-On Tests
We bought and tested both of these mouthpieces ourselves and filmed each test for our YouTube channel.
SnoreRx
We bought SnoreRx and tested it ourselves. The box held the mouthpiece, a storage case and an instruction booklet. The parts that touch your teeth are a soft, moldable lining over a firm frame, and after fitting we had deep, clear tooth impressions. You adjust it by pressing the sides and pulling the lower tray forward a step at a time. The front airway opening is about 3 mm: enough to breathe through, but too small to push your tongue through. Our tester recorded their snoring before using it, then wore SnoreRx for three nights, and the snoring-app recordings showed a significant drop in snoring each night. An overnight oxygen recording made while wearing it stayed above the report’s warning line. We found it comfortable as well as effective.
Full details, photos and screenshots are in our SnoreRx review.
VitalSleep
We bought VitalSleep and tested it ourselves. The kit came with a booklet, a case, and the fitting and adjustment tools. To move the lower tray forward you turn a screw on each side clockwise with the tool, a little at a time. The front airway opening is about 6 mm, wide enough for the tongue to come forward into it. The molding is gentle: you get a light, slightly customized impression rather than deep tooth marks. Our tester snored less over two nights of wearing it, going by the snoring-app recordings, and an overnight oxygen recording stayed above the report’s warning line. One note: the booklet in the kit we tested said to soak it for exactly 10 seconds because it overheats easily, while VitalSleep’s website now says about 45 seconds. Follow the instructions that come with yours.
Full details, photos and screenshots are in our VitalSleep review.
What our testing adds to this comparison: Both devices did their job in our tests, so the choice really does come down to fit, price and guarantee. Two differences we could see first-hand: SnoreRx takes a deep, firm impression of your teeth, while VitalSleep’s impression is lighter; and VitalSleep’s front opening is about twice as wide, which helps if you breathe partly through your mouth.
One tester’s nights are a real-world example, not a clinical trial. Snoring varies from person to person and night to night, and a snoring app or fingertip oxygen recording is not a sleep test.
Who Should Skip Both
- Anyone under 18.
- People with full dentures, braces, loose teeth, or advanced gum disease. Ask your dentist first about crowns, bridges and implants. VitalSleep also rules out implants less than a year old and a large overbite.
- People with a history of TMJ disorder or a jaw that clicks or locks.
- Anyone with central sleep apnea or a serious breathing disorder.
- Anyone who might have obstructive sleep apnea: loud snoring with gasping, pauses in breathing or heavy daytime sleepiness. Snoring can be a sign of apnea, and neither device is a treatment for it, so get a sleep test first (see can snoring mouthpieces treat sleep apnea?).
If teeth or jaw problems rule out both, a tongue-stabilizing device such as Good Morning Snore Solution doesn’t move the jaw at all. See who should not use a snoring mouthpiece.
FAQ: SnoreRx vs VitalSleep
Which is better, SnoreRx or VitalSleep?
For most people with an average-sized mouth, SnoreRx, because it offers the same 1 mm adjustment for half the price. VitalSleep is better if you need the smaller size, grind your teeth, or want a 60-night trial and a year of free replacements.
Is VitalSleep worth twice the price of SnoreRx?
Only if you’ll use what the extra $60 buys: the second size, 30 more nights to decide, and free replacements for a year. The snoring-reduction mechanism is essentially the same.
Are SnoreRx and VitalSleep both FDA-cleared?
Yes. SnoreRx (K153200) and VitalSleep (K201719) are both 510(k)-cleared as over-the-counter aids to reduce snoring in adults 18 and older. Neither is cleared to treat sleep apnea.
Which is better for a small mouth?
VitalSleep, because its women’s size has an arch about 10% smaller. SnoreRx comes in one size, and “too bulky” is its most common complaint.
Can you open your mouth with either one?
Not much. Neither has a hinge. Both have a front opening for some mouth breathing. If you want to open and close your mouth, consider SnoreRx Plus or a hinged design like ZQuiet.
Which lasts longer?
VitalSleep’s maker says about a year with normal use, and SnoreRx’s maker says around 6 to 11 months. Independent reviewers usually cite a year to 18 months. Grinding shortens both. VitalSleep’s free first-year replacements make its lifespan less of a worry.
