The difference between SnoreRx and SnoreRx Plus comes down to two things: SnoreRx Plus has a hinge that lets your jaw open and close while you sleep, and it comes apart into three pieces for cleaning. Everything else is the same: both are boil-and-bite mandibular advancement devices from Apnea Sciences, both adjust in 1 mm steps, both are FDA-cleared to reduce snoring, and both have a 30-night money-back guarantee. SnoreRx costs $59.99 and SnoreRx Plus costs $99.99.
How we tested: We bought and tested both SnoreRx and SnoreRx Plus ourselves; our hands-on notes and video reviews are below.
So the real question is whether the hinge and easier cleaning are worth $40 to you. If you are happy sleeping with your mouth held closed, the original SnoreRx does the same core job for less. If a rigid, locked tray sounds claustrophobic, or you tend to wake up wanting to swallow or yawn, SnoreRx Plus is the one to get.

Quick Verdict
- Buy SnoreRx if price matters most, you sleep fine with your mouth closed, and you mainly want to find out whether jaw advancement stops your snoring.
- Buy SnoreRx Plus if you have tried a rigid mouthguard and felt locked in, you want to be able to open your mouth slightly, swallow and yawn, or you want to clean every surface properly.
- Buy neither if you wear dentures or braces, have loose teeth, gum disease or a history of TMJ disorder, or your snoring comes with gasping or pauses in breathing. See who should skip both.
- Our hands-on tests: both clearly reduced our tester’s snoring, SnoreRx Plus by more than 70% at its default setting.
What Is the Same
A lot more than the price gap suggests. According to the manufacturer, both models “mold to your teeth the same way, adjust the same way, and come with the same fitting handle and storage case.” In practice that means:
- Same job. Both hold the lower jaw slightly forward so the tongue and soft tissue at the back of the throat are less likely to fall back and vibrate. Our guide to how snoring mouthpieces work explains the mechanism.
- Same fitting. Bring a mug of water to a full boil in the microwave (the maker warns against a stovetop pan), submerge the device for 60 seconds, dip it in cool water for a second or two, bite firmly for 30 seconds and let it set in cool water for five minutes. You can redo a shallow impression once.
- Same adjustment. Squeeze the two “SQUEEZE” marks, slide the lower tray to the next number, and release. Both ship at the 1 mm factory setting. The maker says to wear each setting for at least three to five nights before advancing, and that most people settle between 3 and 5 mm. The SnoreRx FAQ gives the range as up to 6 mm, which matches the FDA filing.
- Same warnings. Both booklets list the same contraindications and the same early side effects: extra saliva, dry mouth, and tenderness in the jaw, teeth and gums.
Difference 1: The Hinge
The original SnoreRx is two trays locked together at the front. Once it is in, your upper and lower teeth are held in one fixed relationship all night, and you can only open your mouth as far as the device allows.
SnoreRx Plus adds a middle tray. The upper tray hooks onto the back of that middle tray, and that hook is the hinge. The lower jaw is still held forward at whatever setting you choose, but your mouth can open and close vertically. The manufacturer describes it as letting “your jaw open and close while you sleep, instead of being held in one position.”
Why that matters: a trapped, clenched feeling is one of the most common reasons people give up on rigid mouthguards. Being able to open slightly also makes it easier to swallow, which can help with the drooling many people notice in the first nights. What the hinge does not do is change how far forward your jaw sits, so it should not make the Plus more or less effective at stopping snoring. It is a comfort feature.
One caution: a hinge is not the same as side-to-side freedom. The manufacturer describes vertical opening and closing only. If you want a softer device with more give in every direction, a flexible design such as ZQuiet is the usual alternative.
Difference 2: Cleaning
The Plus comes apart into upper, middle and lower trays. You lift the upper tray off the back of the middle tray and brush each piece separately. On the one-piece original, the joint between the trays is where buildup tends to collect, and you cannot get a toothbrush fully into it.
Care is otherwise identical for both: brush with a toothbrush and toothpaste after each use, air-dry, store in the case, and avoid ammonia, bleach and alcohol-based mouthwash. See how to clean a snoring mouthpiece.
The trade-off: taking the Plus apart adds a minute to your morning routine, and you have to make sure the upper tray is hooked back on properly after each clean or adjustment.
Difference 3: Price
SnoreRx is $59.99, or $99.99 for two. SnoreRx Plus is $99.99, or $154.98 for two. For the price of one Plus you can get two of the original, one for home and one for travel or as a spare.
Replacement cost matters too, because boil-and-bite trays wear out. The SnoreRx FAQ says the device typically lasts around 6 to 11 months of use, and sooner if you grind or clench your teeth. The maker does not publish a separate figure for the Plus. Budget for replacing either one roughly once a year with nightly use. See how long snoring mouthpieces last.
Which One Should You Buy?
| If you… | Choose |
|---|---|
| Want the lowest price for an adjustable, molded device | SnoreRx |
| Are buying a first mouthpiece just to see whether jaw advancement works | SnoreRx |
| Want a spare for travel without paying twice as much | SnoreRx two-pack |
| Felt claustrophobic or “locked shut” in a rigid mouthguard before | SnoreRx Plus |
| Often wake up to swallow, yawn or open your mouth | SnoreRx Plus |
| Care a lot about getting the device fully clean | SnoreRx Plus |
| Grind your teeth hard | Either will wear faster; ask your dentist first (see mouthpieces and teeth grinding) |
Our scores put the Plus slightly ahead overall (9.0 vs 8.8) because of the comfort of the hinge, while the original scores higher on value. If you are genuinely undecided, start with what bothers you more: cost, or the idea of having your mouth held shut all night.

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.
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.
What our testing adds to this comparison: Both models worked in our tests, which fits what the specs suggest: the core fit and jaw advancement are the same, and the Plus mainly adds the hinge and easier cleaning.
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.
What Buyers Report About Each
The verified reviews on the manufacturer’s site are mostly positive about snoring reduction for both models, and they repeat the same handful of complaints: the device feels bulky at first, it can be hard to close your lips over it, teeth and jaw are sore in the first week or two, and heavy users or grinders wear through it sooner than they hoped. A few Plus owners mention that taking it apart to clean adds a little time to the morning; others single out the adjustment and hinge as the reason they prefer it.
Most of those complaints are about the fit and the break-in period rather than the model. The fixes are the same for both:
- Sore jaw: start at 1 mm, wear it for one to three hours while awake for the first two or three days (the maker’s own advice), and go back a setting if soreness lingers. Pain that does not settle means stop and see a dentist. More in jaw pain from a snoring mouthpiece.
- Falls out or feels loose: usually a shallow impression. Redo the fitting once, following the timing exactly. Our fitting guide has tips.
- Still snoring: advance one millimeter at a time, wearing each setting several nights. See how to adjust a snoring mouthpiece. If you are still snoring loudly at the furthest setting you can comfortably wear, talk to a doctor.
For the full list, see our SnoreRx complaints guide.
Who Should Skip Both
Both instruction booklets say not to use the device if you:
- are under 18;
- have central sleep apnea or a respiratory disorder;
- have a history of TMD (temporomandibular joint disorder);
- have loose teeth, abscesses, severe gum disease or advanced periodontal disease;
- wear dentures, braces or other dental appliances;
- have implants, crowns or caps, unless your dentist approves.
The SnoreRx FAQ adds that the device needs your upper and lower four front teeth to be natural. Denture wearers should look at a tongue-based device instead; see mouthpieces for denture wearers and SnoreRx Plus vs Good Morning Snore Solution.
Sleep apnea: both models are cleared only to reduce snoring. Snoring can be a sign of obstructive sleep apnea, so if you have pauses in breathing, choking or gasping at night, morning headaches or heavy daytime sleepiness, see a doctor for a sleep test before relying on either one. Read can snoring mouthpieces treat sleep apnea? Apnea Sciences sells a separate prescription device for diagnosed apnea, compared in ApneaRx vs SnoreRx.
Where to Buy
The 30-night money-back guarantee applies to new customers who buy from snorerx.com, and refunds cover the product price, not shipping. Third-party and secondhand listings do not carry that guarantee, and a used boil-and-bite device cannot be re-molded properly. Details are in where to buy SnoreRx.

Frequently Asked Questions
What is the difference between SnoreRx and SnoreRx Plus?
SnoreRx Plus has a hinge that lets your jaw open and close vertically while you sleep, and it comes apart into three trays for cleaning. The fitting, the 1 mm adjustment, the material, the FDA clearance for snoring and the 30-night guarantee are the same. SnoreRx is $59.99 and SnoreRx Plus is $99.99.
Is SnoreRx Plus better than SnoreRx?
It is more comfortable for many people, not more effective. Both hold the jaw forward the same way and adjust in the same 1 mm steps. The Plus is worth the extra money if a fixed, closed-mouth device bothers you or you want easier cleaning. If neither matters to you, the original is better value.
Is “Snore Rx” vs “Snore Rx Plus” the same comparison?
Yes. “Snore Rx” and “Snore Rx Plus” are just spaced spellings of SnoreRx and SnoreRx Plus, both made by Apnea Sciences.
What do Reddit and other buyer discussions say about SnoreRx vs SnoreRx Plus?
We don’t quote forum posts, but the themes in verified buyer reviews are consistent: both reduce snoring for many people once they find their setting, the Plus’s hinge is the main reason people choose it, and the common complaints for both are bulk, early soreness and wear. If you grind your teeth, expect either one to need replacing sooner.
Can you close your mouth with SnoreRx or SnoreRx Plus?
It depends on your anatomy. The manufacturer says some people can close their lips over the device comfortably and others cannot. The Plus lets your jaw open and close, but it does not make the device smaller.
Are both SnoreRx models FDA-cleared?
The manufacturer states that both models are FDA-cleared for the reduction of snoring and that no prescription is needed. In the FDA 510(k) database, SnoreRx is listed under K153200 and K170825, the latter for over-the-counter use in adults 18 and over. Neither model is cleared to treat sleep apnea.
Can I return SnoreRx Plus if it doesn’t work?
Yes, within 30 days of delivery if you are a new customer who bought from snorerx.com. You get the product price back but not shipping. The manufacturer asks you to call 1-800-546-1984 about fit or adjustment problems before your 30 nights are up.
