R3 (RevivThree) without Support

I do like using it but it cracked all the way down the side on one side of the mouthguard already

It was a struggle to adjust to the appliance. Overly large (medium size) I found myself pushing it out several times during the night.
I deal with clinching and grinding which is funny because I help other deal with intra-oral massage for release. I refer my clients to give Reviv a try to protect their teeth from further damage along with helping palatial expansion to reduce aging by helping keep the Sphenoid from shifting.

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.

I have known for years having my jaw "held" forward and open would help, and it does. I have move mobility in my jaw, I don't clench during the day, and my teeth are shifting.
I have had several neck issues, and shoulder muscle spasms during this, worth it. Stretches during the day, heat packs, and some message have helped.
I feel like things are improving but a couple things that may improve the product. I got the vented R3, wish I hadn't. It's a bit more flexable, and I am worried that my jaw is trying to pull in against it, and it may not be as firm as the solid R3. Also, I wake up chewing it like gum, and I take it out in the middle of the night.
I purchased the daytime guard with my purchase, I haven't molded it. Kind of doesn't make sense while my teeth are moving.
Thanks

I had braces on for almost 4-5 years in my teens and had my 20 year wire retainer break recently. I’m in my forties and have numerous minor-major physical and mental health issues all my life. I only tried the R3 for a few days and I can honestly say it’s helped me more than anything else. And I have tried so many supplements, pills, therapies and modalities. It takes some getting used to for sure but I am so glad I was recommended to try it out!

Unbelievably amazing! Literally saved my wisdom tooth! Dentists said I HAD to get it removed when it started growing in in my early 40s because of multiple painful infections and tooth decay in the tooth next to it. Revive widened my palette enough for it to grow in straight and even created little gaps between my teeth that used to be overlapping. My chronic neck pain is essentially gone and haven’t been sick since I started wearing it. Best value product I’ve ever bought!

The mouthpiece is definitely firmer and I had to use it a few times to get used to it but I really like it. It has significantly reduced my jaw pain and I am very happy with the results.

Fits perfectly and helps me not to grind my teeth.

I’ve been wearing this for a couple months now. Helps with my grinding. Overall I’m feeling great- I’ve lost 8 lbs.

Order delivered and good customer service

It’s the best mouth guard for grinding teeth that I’ve ever used. And I’ve paid for the dentist version. Never again! Highly recommend!
