The choice between SnoreRx Plus and Good Morning Snore Solution depends less on which is “better” and more on your teeth, your jaw and your nose. SnoreRx Plus ($99.99) grips your teeth and moves the lower jaw forward in 1 mm steps. Good Morning Snore Solution (GMSS, $79.94) never touches your teeth. It holds the tip of your tongue forward with gentle suction.
How we tested: We bought and tested both SnoreRx Plus and Good Morning Snore Solution ourselves; our hands-on notes and video reviews are below.
If you have healthy natural teeth, no jaw problems and sometimes breathe through your mouth, SnoreRx Plus is the stronger choice. If you wear dentures, have TMJ pain or dental work you don’t want to load, and breathe easily through your nose, GMSS is the safer fit. This page is about the hinged Plus model; for the original SnoreRx, see Good Morning Snore Solution vs SnoreRx.
Bottom line: SnoreRx Plus takes it overall (9.0 vs 8.3), leading most on effectiveness and best suited for maximum adjustability. Choose Good Morning Snore Solution if no jaw strain / dental work is your priority.

Quick Verdict
- SnoreRx Plus for people with a full set of healthy teeth who want an adjustable device that also leaves room to open the mouth.
- Good Morning Snore Solution for denture wearers, people with jaw or dental problems, and anyone who got a sore jaw from a jaw-advancing mouthpiece, provided the nose is clear at night.
- Neither if you might have sleep apnea and haven’t been tested. Both are cleared for snoring only.
- Our hands-on tests: SnoreRx Plus cut our tester’s snoring by more than 70% at its default setting; GMSS reduced snoring too, but slipped out a few times a night.
Three Questions That Decide It
1. Do you have healthy natural teeth?
SnoreRx Plus needs them. Its booklet rules it out for dentures, braces, loose teeth, abscesses and severe gum disease, and says implants, crowns or caps need your dentist’s approval. GMSS sits between your lips and front teeth or gums and holds the tongue, so it doesn’t depend on teeth at all. Many denture wearers take their dentures out at night and still use it. See best snoring mouthpiece for denture wearers.
No natural teeth, or teeth you need to protect: GMSS.
2. Does your jaw tolerate being held forward?
Any jaw-advancing device can cause morning jaw soreness and, over long periods, bite changes in some people. SnoreRx Plus limits this by starting at 1 mm and letting you stop at the smallest setting that works, but its booklet still lists a history of TMJ disorder as a reason not to use it. GMSS leaves the jaw in its natural position, so it avoids jaw strain and bite changes entirely. More in snoring mouthpieces and TMJ.
TMJ history or jaw pain from past mouthpieces: GMSS.
3. Can you breathe comfortably through your nose all night?
This is where GMSS is strict. Its flange seals your lips around the bulb, so nose breathing isn’t optional. A quick test: close your lips and breathe only through your nose for a minute. If that’s hard, treat the congestion first or choose a jaw device. SnoreRx Plus has an open front for some airflow and a hinge that lets your mouth open, so it is more forgiving of mouth breathing. See best snoring mouthpiece for mouth breathers.
Blocked nose or habitual mouth breathing: SnoreRx Plus.

How Each Device Works
SnoreRx Plus is a three-tray mandibular advancement device. Because the tongue is attached to the lower jaw, moving the jaw forward a few millimeters also pulls the base of the tongue away from the back of the throat. You set the advancement by squeezing the middle tray and sliding the lower tray to the next numbered step. The booklet says most people settle between 3 and 5 mm. The upper tray hooks on at the back to form a hinge, so you can open your mouth slightly during the night.
Good Morning Snore Solution is a single soft piece shaped a little like an oversized pacifier. You squeeze the bulb, put the tip of your tongue in the opening and release, and the suction holds your tongue forward. It works on the tongue directly rather than through the jaw. It was developed by Dr. Leslie Dort, a Calgary dentist who works in dental sleep medicine, and is made by MPowrx Health and Wellness Products. See what is a tongue-stabilizing device.
What the Research Says About Jaw vs Tongue Devices
Neither device has a large independent trial behind it, but there is useful evidence on the two device types. In a randomized crossover trial published in Sleep in 2009 (Deane et al.), 27 people with sleep apnea tried a tongue-stabilizing device and a jaw-advancing splint. Both reduced breathing events by similar amounts, but most participants preferred the jaw splint, and they used the tongue device less. The lesson for snorers is that both types can work, and whichever one you will actually wear every night is the one that helps. That study involved diagnosed sleep apnea under medical supervision; it doesn’t make either over-the-counter device an apnea treatment.

Getting Used to Each One
SnoreRx Plus
- Jaw, tooth or gum soreness in the morning is common at first. The maker suggests wearing it for 1–3 hours while awake on the first 2–3 days and starting at the 1 mm setting.
- Extra saliva or a dry mouth usually settles within days.
- Your bite may feel different for a short while after you take it out. If that doesn’t go away, stop and see your dentist.
Good Morning Snore Solution
- A sore tongue tip is the most common complaint. Squeeze the bulb less for lighter suction and build up wear time; most users say the soreness fades within about four weeks.
- Drooling is common early on. A dry mouth usually means air is escaping around your lips.
- Stomach sleepers and restless sleepers can break the suction against the pillow, and the device may come off during the night.
Our guide on how long it takes to get used to a snoring mouthpiece covers both types.
Price, Guarantee and Lifespan
GMSS is $20 cheaper up front ($79.94 vs $99.99) and usually lasts about a year, sometimes two. SnoreRx Plus has no published lifespan; boil-and-bite devices like it typically last around a year, less if you grind your teeth.
The trial windows are similar in length but work differently. GMSS’s 30 days run from the delivery date. You email for a return authorization (RMA) number and get the device price back, not shipping. SnoreRx Plus’s 30 nights apply to new customers buying at snorerx.com and also refund the product price only. With GMSS, start wearing it as soon as it arrives so you are past the sore-tongue phase before the window closes.

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.
Good Morning Snore Solution
We bought Good Morning Snore Solution and tested it ourselves. The box held the device, directions for use, a packet of cleaning solution and a storage case. You place the flange between your lips and front teeth, squeeze the bulb, put the tip of your tongue in and let go. Over three nights our tester snored less, though some snoring remained, and an overnight oxygen recording showed adequate oxygen levels. It fell out a few times during the night, and because it sticks out of the mouth, our tester had to sleep on their back to keep it in. You need to breathe well through your nose, and the booklet warns it can take up to six weeks to get used to it.
Full details, photos and screenshots are in our Good Morning Snore Solution review.
What our testing adds to this comparison: Both reduced our tester’s snoring, but they asked very different things of the wearer. SnoreRx Plus worked at its default setting. GMSS fell out a few times a night and our tester had to sleep on their back with it, which is worth knowing if you sleep on your side.
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.
Safety: Who Should Check With a Professional First
- Everyone with sleep apnea warning signs. Loud snoring with gasping, choking, pauses in breathing or heavy daytime sleepiness can mean obstructive sleep apnea. Get a sleep test before using either device. Read can snoring mouthpieces treat sleep apnea?
- Under 18s. Both are cleared for adults only.
- SnoreRx Plus specifically: not for central sleep apnea or other respiratory disorders, a history of TMJ disorder, dentures, braces, loose teeth or advanced gum disease.
- GMSS specifically: not for chronic nasal blockage, and stop if the tongue becomes cut, ulcerated or numb.

Frequently Asked Questions
Is SnoreRx Plus or Good Morning Snore Solution more effective?
We score SnoreRx Plus 9.3 for effectiveness and GMSS 8.5, mainly because SnoreRx Plus can be fine-tuned. But a tongue device that suits you will beat a jaw device you can’t tolerate, so let your teeth, jaw and nose make the call.
Can I use SnoreRx Plus with dentures?
No. Its instructions rule out dentures. Good Morning Snore Solution doesn’t need teeth and is a common choice for denture wearers.
Which is better for TMJ?
GMSS, because it doesn’t move the jaw. SnoreRx Plus is not recommended if you have a history of TMJ disorder. Ask your dentist either way.
Can I use Good Morning Snore Solution if I breathe through my mouth?
Usually not. It needs comfortable nose breathing all night. A jaw device such as SnoreRx Plus, which has an open front and a hinge, is more forgiving.
How does SnoreRx Plus differ from the original SnoreRx against GMSS?
Both SnoreRx models adjust in 1 mm steps; the Plus adds a hinge and three take-apart trays for $40 more. The comparison with the original is in Good Morning Snore Solution vs SnoreRx.
