R3 (RevivThree) without Support

I’ve been using Reviv 3 for about two months now — although I haven’t been completely consistent because of my summer travels. And even with that, I started noticing some changes surprisingly quickly.

One of the first things I noticed was how much more relaxed my jaw felt. I also used to feel a certain pressure and tension around the joint area — not exactly pain, but that feeling that your jaw is constantly holding tension. Little by little, I’ve noticed that feeling becoming much less noticeable.

I’ve also started noticing changes in my bite and smile. My lower jaw seems to be gradually coming forward into a more natural position, and my teeth look straighter and more aligned. My smile also feels a little broader and more balanced.

When I first started wearing Reviv 3, I have to admit it felt uncomfortable and strange. It takes some time for your mouth and jaw to adapt to having something there during sleep. But now it’s completely different.

I honestly don’t even notice it anymore. There’s no feeling of having a foreign object in my mouth, and I can comfortably sleep with it from bedtime until morning. It has simply become part of my nighttime routine.

What I especially like is that the changes don’t feel forced. It’s more like my jaw and facial muscles are gradually learning a more relaxed position.

Another thing I’ve really been enjoying is incorporating Reviv 3 into my face yoga practice.

I can actually feel a difference when I do my exercises with Reviv 3 compared to doing the same exercises without it. Especially during exercises involving the lower face, I feel that the movements become more focused and that I can better connect with the muscles I’m working on.

As someone who practices and teaches functional face yoga, I would definitely recommend experimenting with Reviv 3 alongside your face yoga exercises.

For me, it has become a really interesting addition to my face yoga routine.

I’m only two months in, and I know I haven’t even been using it consistently yet, so I’m really curious to see what happens with more regular use over the next few months.

For me, the biggest surprise has been how something so simple can gradually change the way my entire lower face feels.
Looking forward to continuing my Reviv 3 journey and seeing how much more I notice with consistent use.

Only using it at night and was consistent with it.

I ordered a medium size but it kept coming out. I contacted the CS team and they sorted it out for me quickly! Thank you!

I had wisdom teeth extraction months before I started reviv3. Now a couple months in I noticed my face and smile look more symmetrical.

Got it for TMJ issue and I’d say the results are still intermittent maybe it’s gonna take more time. Some headaches in the first couple weeks then it resolves itself after.

Look forward to using it longer and seeing more benefits

I’ve been using the RevivThree mouth guard for a couple of months now, and I’m very happy with it. The fit is comfortable, it stays in place throughout the night, and it has done a great job protecting my teeth from clenching and grinding.

I used to wake up with sore teeth and jaw tension, and while I still have some TMJ-related issues, this mouth guard has definitely helped reduce the wear on my teeth and given me peace of mind while sleeping. It’s durable, easy to clean, and much more comfortable than I expected.

I would absolutely recommend it to anyone looking for a quality night guard to help protect their teeth from grinding and clenching. ⭐⭐⭐⭐⭐

I absolutely love my reviv 3 - it’s made my smile broader and straight.
I had done an Invisalign treatment and teeth moved to original position. I would have to pay $5500 for another treatment but Reviv 3 is way cheaper.
It’s an amazing investment.
I also take a pinch of xylitol before bed it help teeth stay hydrated overnight.

Great results so far. Have been using under 2 months. Have noticed results in jaw and teeth. Took a bit to get used to in the beginning but was able to sleep with it in from wearing it for a few hours during the day. Definitely preferred this mouthguard to the R1.

I enjoy wearing this for what it does to my jaw tension, however, the holes in the bottom and top unfortunately suction to my lips as I sleep and create painful welts if I wear this more than 3 or so days in a row.

Amazing 👏 I knew it would work after the first night of use it's been a few months and I can't sleep without myR3. It's very comfortable and actually feels good to wear . I will be a life long customer.

So, I bought two pairs of these, as my boyfriend and I have been using the R2's since July last year. We were worried about the stiffness of the material and what looked like less support on the inside behind the teeth BUT- this one is by far the best. The material makes it easier to spread the teeth and the support is just right around the inside and outer gums. The R2 gave me some recession on one tooth, that the R3 does not. We have both seen a lot more movement with this one. I saw other reviews about the hardness being a detractor but after having worn this for more than 3 months and trying out my old R2 again, it doesn't even feel the same.

After starting my oral journey in July, I can take deeper breaths through my nose, my teeth stay cleaner, and it is significantly easier to brush. When I tell you I could not jog or run without eventually breathing through my mouth because the gulps of air I was getting through my nose was not enough. I can run using just my nose for much longer and have noticed less swelling in my outer jaw/mandibular joint. I had braces before, but it did not fix width, breathing, or alignment. Over the last 9 months, my face looks slimmer, my teeth are wider, and I can freaking breathe!

I went from the large r2 to the xl r3 and its sooo much more comfortable. I cut off the tabs that rest on the back molars because the mouthpiece was too long. The width stretched out my pallet within a few daysto allow it to comfortably fit. I had to fully mouthwatering with the lg r2 to keep from drooling too much and dont have to with the xlr3 even though its substantially wider although I still prefer mouthtaping. My beginning pictures from October until now (February) are unreal! Highly recommended to everyone!

Much improved thickness- R3’s thickness makes it feel much more effective. However, the thickness is everywhere, which is better for applying force to the teeth and face, but makes the mouthguard material harder and less flexible, and harder to nose breathe.

The lower height in front makes it much more comfortable than the R2 on the gums. The R3 tongue retainer is less intrusive and retains less saliva but I prefer the feel of it on the R2.

R2 continuously gets wider in the rear, and the tongue retainer tapers earlier, to provide more space for the back of the tongue. R3 has more of a U shape that feels more narrow toward the rear of the mouth.

XL is too long for me (6’2” 215 lbs 60cm head circumference) but I like the added width. R2 Large feels a little small, and the R3 XL didn’t fit in my mouth until I cut it. I don’t recommend cutting it as it will be sharper and less comfortable than if it was in its original shape. It’s significantly bigger than the Large.

I hope future models take some of the R2 design, no holes, better tongue retainer and taper, thinner in the front. Combined with the R3’s thickness between teeth & lower gum line. Hope to see more size options and perhaps a fitting system/guide in the future. Awesome product 👍

I Recently got it, I haven’t tried it on yet but it looks great and i will be wearing it during the day tomorrow. Because I’m letting it air out, I will post an update after wearing it so far i’m very pleased with it. Here below are pictures of the Top of the mouth guard, the front, the Side and the bottom.

It's been 2 weeks and I already see and feel a change in my face and smile. I am smiling more and more without covering it.

No return policy, does not fit properly and is extremely uncomfortable

Doesn’t fit my mouth. Too big even though I ordered a size small. Horrible for tongue posture

I really do not like the fit or the lack of security to keep it in my mouth. I prefer the harder ones that stay in place. Too many videos praising this product got me to buy one. And now im stuck with it .

I am happy with R3. I like that the outside of the guard is lower down so it doesn't hit the gums.
Thanks.

i LOVE my r3!

R3 is an interesting experience. I personally thought it was more comfortable than the R2 but I don't get the same type of jaw stretching as I do with the R2. In fact I would say although it's more comfortable, it performs differently. When I first used the R2 is was excruciating. I could only keep it in for a few seconds but then I felt my whole face and forehead stretch and eventually got past the pain. I never bought the R1.

The R3 stretches the top of my pallet way more than the R2 so I don't have my bottom teeth touching my top teeth. I wear it mostly at my computer.

With both guards I do not keep them in when I sleep. I keep meaning to buy mouth tape to see if that helps but haven't yet.

Obsessed!
I have a deep overbite so it’s slightly more challenging to get it to stay in over night but it’s getting easier. The stretch it gives me is amazing. Teeth are starting to shift as I get closer to keeping my bite open. Lots of unexpected body benefits.
Loving the community forum, learning so much through others and Ken. Nothing to lose and all to gain in my view 🙌

I started using it as soon as it arrived, and so far I don’t see any aesthetic changes, but I feel like brain fog has definitely cleared up. I’m looking dieses to wearing it more!

I have issues where bottom teeth go away from mouth bridge.

Overall I'm very pleased with it. I wear it quite often, forgetting once in a while. My one concern is that my lower front tooth hits my upper front tooth in the mornings when I get up. I had recent restorative work done and would hate to jeopardize it.
