I got this to help relax my jaw because of trigeminal nerve issues

I got this to help relax my jaw because of trigeminal nerve issues. My Dr and physio had recommended a mouth guard. It had definitely had a positive impact on muscle tension in my neck and jaws and I’m noticing more symmetrical facial as l features and improvement in lower jaw tooth crowding. I can feel that my palate is now wider and flatter too. It took a few weeks before it stayed in all night, but now I’m more comfortable wearing it at night than going without.

Fantastic mouthguard

Really felt the difference over the past months, I sleep better and my facial structure started to align pretty quickly. Some funny effects as well is that I'm not anxious anymore, more social and not a people pleaser anymore! I switch between the R1 and R1.. the R1 is more comfortable to wear in the daytime, for sleep I prefer the R2

Been difficult to wear

Been difficult to wear. I had to cut off the tongue guide because I got an ulcer so bad it took 2.5 weeks to go away. I also cut 2 horizontal holes in the sides for saliva to move through more. I still get tissue soreness so I have to go start again very slowly.

Better than Starecta

I'm quite familiar with meme appliances like Starecta and conduct a bit of biomechanical study (mostly PRI) to address my asymmetries. RevivTwo is a great little appliance that has been giving me very steady gains.

It's not going to change you if you don't know what your goals should be, that is a more symmetrical, healthier, biomechanically sturdier body. You can for sure use this device wrong by locking into a bite that's comfortable yet chronically damaging to you -- your old bite essentially.

So it has already begun straightening my front 2 teeth. It has also shifted my lower jaw more to the right, although I'm less symmetrical when aligning teeth, overall I'm more symmetrical everywhere else. Have been wearing it anywhere between 4 to 12 hours a day, every day.

Doesn't smell as bad as the Starecta with regular use. Well constructed. Pretty comfortable when you get used to it. It doesn't have weird manufacturing edges and defects that irritate the mouth.

The mouthgard is very comfortable

Don't no which results will come but the mouthgard is very comfortable, even when sleeping. Support from Revive is great. So far so very good!

This night guard is life changing!

This night guard is life changing! Prefer the R2 to the R3 and I am a big grinder. Also paired the guard with toe spacer socks to sleep which has helped relax my jaw and reducing the night time clenching/grinding.
Also has straighten my bottom teeth in about 2 months! Cannot recommend enough!

I’m surprised how it fit perfectly and the material was great unfortunately I haven’t tried it tonight but it felt so comfortable and relaxing. I hope it gives me a good sleep. I wish I wouldn’t have pushed the stars already so I could’ve put a review on what it was like waking up tomorrow, but I was very satisfied in the material and how it fit. But I have a small mouth medium is very small for my very small mouth!! I measured only half of what the guy did in the video and I was surprised how small this was. I was just happy. It was perfect for me. I would like to write another review to see how it goes on how it stays, but I can’t do that. It’s too late now, but you must go up larger that I will tell you.!!!!!!!*****

I've lost 3 teeth to bruxism

I've lost 3 teeth to bruxism, grinding and stress in the last 9 years mostly molars despite using tailor made guards. I was on the way to lose more until this. I feel it has realigned things and repositioned my bite to slow the self attacks. I wish it was a bit thinner and easier to wear however as it feels large and clumpy in the mouth and sometimes pops out but otherwise great. Thank you!

I'm amazed at how well this works. I wasn't expecting much except to not grind at night. I've always had straight top teeth, but have dealt with crooked lower teeth my entire life. I didn't expect to see any straightening for months, but in less than 60 days I feel there is definitely a difference in my bite. I definitely recommend it!

Really hard to wear because it’s so big that I cannot close my mouth at night

Really hard to wear because it’s so big that I cannot close my mouth at night. Gives me a dry mouth. Nikki the silicone material and breathing holes though. Also too much saliva builds up in my mouth.

The 'so big I can't close my mouth' feeling is often the vertical height the guard adds before your soft tissue has stretched to accommodate it — it eases as you adjust.

The key is to ease in rather than go straight to full nights: start with short intervals during the day and build up gradually. Closing around it gets easier as the tissue stretches.

Mouth taping at night is the most useful lever here — it keeps your lips sealed, which tackles both the dry mouth (from your mouth staying open) and the saliva pooling, and it helps hold the guard in place too. The extra saliva is also common early on and settles as your mouth adjusts.

Terrible for grinding, uncomfortable to sleep with in, mine fell apart not long after purchase

Hi,

Sorry to hear it — that's a frustrating experience

Note that the R2 comes with a 1-year replacement so you can write to support if you want to take advantage of that.

On the comfort side, easing in gradually — shorter intervals during the day before building up to nights — usually makes a big difference there too.

Needs modification.(not like the R3 tho)

It’s fine. I know It works because my jaw and teeth hurt after using it but I find the tip that sits on the roof of your mouth a bit useless. I have been mewing for years so I don’t need It( I know It’s for reminding to keep your tongue there If not then sorry for the mistake) and It just bothers me and it just hurts and dries my roof. Other than that it’s pretty rough on the gums as well sometimes but I need to wear It longer to confirm actual results.

Painful

It’s extremely painful

Hi Holly,

we're sorry to hear about your discomfort. This process often does include some level of pain for some folks at the beginning.

But it can usually be mitigated to a large extent by just going slower and taking more breaks.

We recommend shorter intervals during the day (even 15-30 minutes) rather than overnight, and build up very gradually. The process is built around sustained use over months and years, so there's no rush.

I really am amazed by this appliance

I really am amazed by this appliance. I have tried so many night guards and they never stayed in through the night. This one is a game changer. Not only does it stay in but my sleep quality has completely gotten better. I really didn’t know I had a sleep issue. I bought it for grinding and the benefits just keep unfolding. I am a very satisfied customer and I’ll never give up this product. Thank you so much!

Getting good results, 2 months in

I've been wearing my Reviv2 for about 2 months. I don't sleep in it (not a teeth grinder, and because I cough from saliva). I wear it almost daily, around the house or while watching tv, for 60-90 minutes. At first, there was a sore spot on my gumline, but as my teeth/bite shifts, that is going away. I've learned that when my teeth start feeling pretty sore (during/after use), that often precedes a bad headache. Trial and error, learning how to pace myself. If I get a headache, I take a day or two off. After 2 months, I notice my smile is brighter, wider, and more even. My cross-bite is reduced. My singing voice/pitch is improving. My neck tension is reducing, with better mobility. I'm happy with my Reviv device and it seems quite durable. I will eventually share my before/after photos...already I can see and feel the difference!

Worth mentioning: I have been adding in facial massage, inner-mouth massage, and doing Craniosacral therapy (CST) on myself. All of this is a good pairing with the Reviv device...it's speeding up my good results. When wearing the device, I visualize my jaw/teeth/face shifting towards center alignment, balanced from side to side. I'll massage facial muscles and do CST too. After wearing the device, I do inner mouth releases (and more CST). All this releases soft-tissue tensions that impact tooth, hard palate, cranial bones, and jaw alignment. I do bodywork professionally, but for anyone interested to learn, check out a book called "Harmonizing Your CranioSacral Rhythm by Daniel Agustoni.

I am wearing them for 3 months now and didn’t see any big difference

I am wearing them for 3 months now and didn’t see any big difference. I shouldhave bought Reviv3.

The main reason most folks plateau is they haven't unlocked their bite. The remedy is to go very hard on daytime wear for some weeks. Worth a read in the community: https://www.skool.com/reviv-2885/the-importance-of-unlocking-your-bite

Start with R1 first- and be patient with R2

If you have sensitive teeth/gums, I highly recommend starting with the R1 first. It took a lot longer for my gums to adjust to the R2 but the discipline and perseverance really paid off! I sleep better and have had an ongoing significant reduction in chronic myofascial pain since I began with the R1 and progressed onto the R2. These devices just about saved my life! I’m able to work five days a week now whereas I could hardly function from pain and exhaustion before.

HOW REVIV WORKS

We believe there are some biomechanics to how the skeleton and skull work, which result in it collapsing over time.

Particularly if you did orthodontics, extractions, or grind your teeth our experience is that this could result in the skull sort of 'deflating'.

And a simple mouthguard like Reviv can 'reinflate' it by stretching the soft tissue that covers the skull.

Jaw issues

"I've been wearing my appliance for 3 weeks now. No more TMJ pain at all! I can do chin tuck exercises without my neck muscles spasming and cramping." - Jay

Energy

"I wear it when driving the bus. A day of work that normally knocks me out the next day had me full of energy. Even when i got home after a very long day. I love this thing!" - George

Mental Clarity

"Although i'm a software developer I spent about a year carrying boxes in a warehouse because of the thick brain fog i had. I've been wearing Reviv since early November and brain fog is gone. I just recently started a job working as a developer again!" - Ivan

Posture

"I noticed the other day the area where my neck meets my upper back is more flat . I always had a bit of kyphosis and rounded soldiers and it seems to be correcting." - Harvwin

Frequently Asked Questions

How should I start Reviv? Is there anything to be aware of?

Yes there are a few things to know going in.

On wearing it: The standard pattern is overnight + 2-3 hours during the day. Build up gradually with shorter intervals during the day first rather than going straight to overnights — that helps the soft tissue adjust. Most folks find the early phase is the hardest part and it gets significantly easier after a few weeks usually.

On early discomfort: Pretty common in the first few weeks. Sore teeth, achy gums, occasional small sores in the mouth, the lips not closing fully, extra saliva — all signs the soft tissue is stretching, not signs something is wrong. Take it at your own pace. If the soreness gets sharp, take a short break — a few hours or even a day or two off is fine. Stick with it but don't push through pain.

On accelerating results: What matters most is consistent use and then stretching to accelerate. The Fast Method in our Skool community has some stretches we recommend, including the Bite & Hold exercise that works alongside the mouthguard: https://www.skool.com/reviv-2885/classroom/8ca49f79?md=90728adac0e5463680dc40a43e294104

On mouth taping: A lot of folks tape at night to keep the mouth closed and help with guard retention while the tissue is still adjusting. Pairs well with the Reviv.

Why does this work?

Think of the soft tissue (e.g., fascia & skin) covering the bones of the skull as a balloon. When you grind your teeth down, it is as if you're taking air out of the balloon.

When this balloon deflates, it crushes the skull, which in turn crushes the brain and causes cognitive and neurological issues over time.

In general, we as a society like to call this process 'aging.' But if you grind down your teeth faster, you 'age' faster. The good part is you can reverse the process by using the same physics in reverse, i.e., you 'add' height back to the teeth.

How many people have done this process?

Over 20,000 people have started using the appliance and this method since late 2024.

How does sizing work?

Note that there is a 'Size chart' above that you should refer to for measurements of our appliances.

We recommend choosing size based on the instructions in this video (link)
