Bottom line: It’s close: SnoreRx Plus edges ahead (9.0 vs 8.8), and it is also the less expensive of the two ($99.99 vs $119.95). VitalSleep has the longer guarantee (60 nights vs 30) plus a 1-year warranty with free replacements, and is the better pick if that matters most to you.
Short answer: SnoreRx Plus and VitalSleep both mold to your teeth and move your lower jaw forward in 1 mm steps, so they reduce snoring the same way. The real difference is what it’s like to live with each one. SnoreRx Plus has a hinge, so your mouth can open and close during the night, and it comes apart for cleaning. It costs $99.99. VitalSleep has no hinge but comes in two sizes and has the longer safety net: 60 nights to return it and a year of free replacements, for $119.95. If being held shut all night is what puts you off mouthpieces, choose SnoreRx Plus. If your mouth is small or you grind your teeth, choose VitalSleep.

Quick Verdict
- Choose SnoreRx Plus if you want to open your mouth, swallow and yawn more naturally, want the easiest device to clean, and want calibrated adjustment for $20 less.
- Choose VitalSleep if standard-size trays feel too big, you grind your teeth and expect to replace the device within a year, or you want 60 nights rather than 30 to decide.
- Choose neither if you have dentures, loose teeth, gum disease or TMJ problems, or possible sleep apnea that hasn’t been checked.
- Our hands-on tests: SnoreRx Plus cut our tester’s snoring by more than 70% at its default setting; VitalSleep also reduced snoring and has a wider (about 6 mm) front opening.

The Big Difference: Hinge vs Fixed Trays
Many people who give up on mouthpieces don’t quit because the device failed to stop their snoring. They quit because they couldn’t stand having their mouth held shut. They describe feeling trapped or clenched, or waking up because they couldn’t swallow or yawn. SnoreRx Plus is designed around that problem. Its upper tray hooks onto the back of a middle tray, and that connection acts as a hinge, so your jaw can open and close vertically while the lower tray stays advanced. Being able to open slightly also makes swallowing easier, which can help with the drooling that is common early on.
VitalSleep doesn’t have that. Its maker says plainly that there’s no hinge and mouth movement is limited while it’s in. It does have a front opening, so you can still breathe through your mouth, and the maker notes that people with smaller mouths may not be able to close fully. Plenty of people sleep fine in a fixed device. But if you already know you hate the locked-in feeling, or you tried a rigid tray and pulled it out at 3 a.m., the hinge is the reason to pick SnoreRx Plus.
Winner for freedom of movement: SnoreRx Plus.
Fit: One Size vs Two
Here the advantage reverses. SnoreRx Plus comes in one size, and a three-tray hinged design isn’t small. “Too bulky” is a recurring complaint, especially from people with a pronounced overbite. VitalSleep sells a standard (men’s) size and a women’s size with an arch about 10% smaller. The maker publishes the dimensions: 61.1 mm long and 47.7 mm wide for the small, against 67.5 × 50.1 mm for the standard. It also exchanges sizes for free without using up your trial.
Both are boil-and-bite, and with both the impression decides whether the device stays in at night. SnoreRx Plus is strict about it: microwave-boiled water for exactly one minute, a 30-second bite, five minutes to set, and only two attempts. VitalSleep’s process is 45 seconds in hot water and 3 in cold, then a gentle, even bite. It can be re-molded, and the maker replaces it free if the fit goes wrong. See how to fit an anti-snoring mouthpiece and best snoring mouthpiece for small mouths.
Winner for fit options: VitalSleep.
Adjusting Night to Night
Both move the jaw in 1 mm steps, which is what you want. Start low, advance slowly, and stop at the first setting that controls your snoring. SnoreRx Plus starts at 1 mm. You unhook the upper tray, squeeze the “SQUEEZE” tabs on the middle tray, slide the lower tray to the next number and hook the upper tray back on. The booklet says to give each setting three to five nights and that most people settle at 3–5 mm.
VitalSleep starts at zero. You turn a screw on each side clockwise with the included tool and set both sides to the same mark. The maker says not to advance at all for the first few nights, then to move in small steps. The squeeze-and-slide is faster and needs no tool. The screws let you set each side individually, but uneven sides are the most common mistake. Step-by-step help is in how to adjust a snoring mouthpiece.
Winner: tie.
Cleaning and Upkeep
SnoreRx Plus comes apart into three pieces, so you can brush every surface, including the hinge area where buildup tends to collect. The maker recommends a soft toothbrush and toothpaste after each use and air-drying. Avoid ammonia, bleach and alcohol-based mouthwash.
VitalSleep is one piece. Clean it daily with a soft brush and toothpaste in cool water, or soak it in denture cleaner for about 15 minutes. Never use hot water after fitting, and avoid bleach and abrasive cleaners. Both are easy enough to look after, but the take-apart design gives SnoreRx Plus the edge. See how to clean a snoring mouthpiece.
Winner: SnoreRx Plus.
The Real First-Year Cost
The sticker prices are $99.99 for SnoreRx Plus and $119.95 for VitalSleep, a $19.96 difference. What happens after you buy matters more:
- Trial period. SnoreRx Plus gives you 30 nights and refunds the product price but not shipping. VitalSleep gives you 60 nights from the delivery date with a prepaid U.S. return label. Both guarantees apply only to orders from the maker’s own site.
- Wear and tear. Boil-and-bite devices typically last about a year of nightly use, and heavy grinders get less. VitalSleep sends free replacements for the first year, and the maker says there’s no limit on how many. SnoreRx Plus has no advertised warranty, but its two-pack ($154.98) gives you a spare for about $77 each.
For someone who doesn’t grind and settles in within a few weeks, SnoreRx Plus is the cheaper choice. For a grinder who might wear through a device in six months, VitalSleep’s replacement program can make it the cheaper one over the first year. See snoring mouthpieces and teeth grinding and how long snoring mouthpieces last.
Winner: depends on you. SnoreRx Plus for most people; VitalSleep for grinders and anyone who needs a longer trial.

Our Hands-On Tests
We bought and tested both of these mouthpieces ourselves and filmed each test for our YouTube channel.
SnoreRx Plus
We bought SnoreRx Plus and tested it ourselves. It arrived with the fitting handle already in place, plus a case and instructions. We fitted it with a cup of water boiled in the microwave: 60 seconds in the water, a firm 30-second bite and 5 minutes in cool water, which left a clear impression of the teeth. Tested at the factory default setting, with no extra advancement, our recordings consistently showed snoring reduced by more than 70%. If you do advance it, the instructions say to go 1 mm at a time, every few nights.
Full details, photos and screenshots are in our SnoreRx Plus 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 reduced snoring in our tests. SnoreRx Plus did it at its default setting, before any adjustment. If you breathe through your mouth, VitalSleep’s wide front opening was the more open of the two.
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
Both devices grip the teeth to hold the jaw forward. Don’t use either if you are under 18; wear full dentures or braces; have loose teeth, abscesses or advanced gum disease; have a history of TMJ disorder; or have central sleep apnea or a serious breathing disorder. Ask your dentist first about crowns, bridges and implants. VitalSleep also rules out implants less than a year old and a large overbite. Snoring can be a sign of obstructive sleep apnea, and neither device is a treatment for it. If you gasp, stop breathing in your sleep or are very sleepy during the day, see a doctor first (read can snoring mouthpieces treat sleep apnea?). If your teeth or jaw rule out a MAD, look at a tongue-stabilizing device.
FAQ: SnoreRx Plus vs VitalSleep
Is SnoreRx Plus better than VitalSleep?
For most people, yes. It scores 9.0 to VitalSleep’s 8.8 with us, mainly because of the hinge and the take-apart cleaning, and it costs $19.96 less. VitalSleep is the better choice for small mouths, teeth grinders, and anyone who wants a 60-night trial.
Which is more comfortable?
It depends on what bothers you. If a fixed, closed-mouth position feels confining, SnoreRx Plus’s hinge is more comfortable. If standard-size trays feel too big, VitalSleep’s smaller size is. Both cause some jaw soreness and extra saliva in the first week or two.
Can I breathe through my mouth with either one?
Both have an opening at the front that allows some mouth breathing. If you breathe mostly through your mouth because of congestion, deal with the nasal problem too. See best snoring mouthpiece for mouth breathers.
Which is better for women?
Fit matters more than gender. VitalSleep is the only one of the two with a smaller size, so it’s the safer pick for a small mouth. A woman with an average-sized jaw can do just as well with SnoreRx Plus. See best snoring mouthpiece for women.
Does either one treat sleep apnea?
No. Both are sold to reduce snoring in adults, and both makers state they aren’t sleep apnea treatments. Get a sleep test if you have symptoms of apnea.
How long do they last?
About a year of nightly use is typical for boil-and-bite devices like these, and less if you grind. VitalSleep replaces yours free during the first year. SnoreRx Plus offers a two-pack instead.
