Extremely Disappointed with Reviv

Extremely disappointed with Reviv Mouthguards. The product provided no real benefit and did not live up to the expectations at all. It felt like a complete waste of money.

On top of that, their customer service was some of the most unprofessional I’ve ever dealt with unhelpful, and more interested in avoiding responsibility than actually helping the customer.

I would not recommend this company to anyone. Save your money and look elsewhere.

Horrible product with horrible customer…

Horrible product with horrible customer service. Item does not produce any results even after months of wearing. All it has done is damage my gums and mouth.

Customer support is non existent. No returns and no refunds. It does not matter if the item cannot be reused. They should trust in their product enough to offer refunds. Obviously they do not have that trust in it.

Don't trust the reviews on their website. They just delete negative reviews immediately.

Hmmm if I am correct your order# is 30891 and you've been arguing all day with us about getting a refund despite the fact that we told you that our policy on successful deliveries, which you claim is missing, is that we only resend and do not refund.

And as such your order was made on April 13th and your claim that it "does not produce any results even after months of wearing. All it has done is damage my gums and mouth." is a complete and utter lie.

So i guess folks can listen to thousands of people talking in our skool community about their results... or they can believe you who claims to have been wearing it for months despite ordering less than 2 weeks ago.

Sent a product with a KNOWN DEFECT.

This company sent me a product that HAD A KNOWN CURING DEFECT. It's NOT safe. They knew that this product wasn't cured properly and they sent it to me anyway. It has a horrible smell and taste and is UNUSABLE. They are willfully sending undsafe products because the product that I ordered wasn't in stock. I had to reach out after a month of not hearing from them about my purchase. They admitted that the batch had a know curing defect. This makes the product unusable. Although the material they use may be safe, they cannot support that claim when the device hasn't been cured properly. It tastes like literal POISON. Con artists.

Nope, the smell/taste has not dissipated after doing what you said, and yes it is a curing defect. You admitted it in your email, the product was sealed too soon causing a defect in the off-gassing aka curing of the product. You willfully sent it to me anyway after radio-silence for a month after my order. AND I QUOTE FROM YOUR OWN EMAIL is a known issue with 1-2 batches where the supplier did not wait the full 3 days before sealing the bags. It is not toxic — it is just residual smell from the silicone curing process.

THE PRODUCT WAW IMPROPERLY CURED YOU MORONS. Like I said: acrylic nails are safe but they are ABSOLUTELY not safe if they’re not cured properly. Dumbasses

I'm sorry but we don't agree with pretty much anything you have written.

We mentioned that after manufacturing the supplier often waits a couple of days to let the smell of manufacturing air out. And there was a batch where they were bagged before the smell fully dissipated.

The smell is not toxic and typically goes away after washing a few times. We also offered to send you a new one for free in case it did not... but you declined and preferred a refund. So we refunded.

Note that this has nothing to do with the 'curing', which is a step in the manufacturing process, and was not impacted at all. We never mentioned any issues with curing as there was none. So i think you are just mixing (or perhaps purposefully changing) your facts.

Mouthguard is very uncomfortable and causes tooth and gum pain. When I tried to return it, I found out they have a no return policy.

The return policy is part of the terms & conditions that are mandatory to accept before purchase. And it is a hygiene item that a person puts in their mouth. So it should not have come as a surprise that it was not returnable.

Terrible terrible experience

Terrible.
Contacted company to be told tough it out for a week or you won’t see results.
I keep choking. The device is far too big and Chokes me quite literally.
I am told it will work if I keep trying.
No help.
No refund.
Nothing but telling me everyone else loves it “look at our reviews!”
All reviews on their website are chosen by them not actual reviews. Just hand picked.
DO NOT TRUST THIS COMPANY ON ANY ACCOUNT IT IS A WASTE OF TIME AND MONEY.
Customer service is unhelpful and rude.

The process is difficult for some folks early on and we recommended starting with short daytime intervals.

We also recommending joining our skool community (we give 30 days free) as there are probably hundreds of stories like yours where it's hard at first.. and then they get thru.

You prefer to ignore our recommendations and demand that we adhere to a guarantee that hasn't existed since September 2025.

We refused and you started threatening us.

You claim the reviews on our website are not 'actual' reviews but you obviously do not know anything about the Judgeme platform because if you did you would know that it is next to impossible for us to fictitiously create hundreds of reviews by verified purchasers.

As we'd literally need to create hundreds of Shopify accounts, make orders, have them delivered, and then create these reviews.

Anyway, all the best to you.

Finally Feel Like Myself Again

I’ve been using Reviv 3 for a couple of weeks now and honestly, the difference is noticeable. I feel more energised throughout the day, less sluggish, and my overall recovery (especially after busy days or workouts) has improved a lot.

What I love most is how quickly it works no long waiting time. It just gives you that clean boost without feeling jittery or artificial.

It’s become part of my routine now, and I can definitely see the long-term benefits. Highly recommend if you’re looking to feel more balanced, refreshed, and on top of your game.

Superior Customer Service

So far I've had the mouthguard for a few days, and it's taking some getting used to, but I can tell it is working. However, I needed to change sizes and they have the most responsive customer service I think I have ever experienced. They responded insanely fast and their size change policy is so reasonable and easy to navigate. A+ customer service I wish every company was like them

I’ve been wearing the Reviv 3 mouth…

I’ve been wearing the Reviv 3 mouth guard for 3 nights now and I’m already really excited about it. The first couple of nights were a little uncomfortable as my teeth adjusted, but by the third night it was honestly a breeze to wear.

What surprised me most is that my husband already mentioned my teeth look neater, even after such a short time. That made me even more motivated to keep going!

I’m really excited to see how my smile improves over the coming weeks. I’ll definitely keep updating my progress and sharing my results along the journey. 😊

R3 is the best!

I started with an R1 and it was ok. I thought the squishy material would be comfortable as I am not used to sleeping with a nightguard (I have in the past but not regularly). It was comfortable and I built up my tolerance to wearing all night but would take breaks with it since it was a bit irritating to my gums. I already have receding gums so I was worried it would make it worse. I did wake up with some bleeding one morning and couldn’t wear the R1 for several days afterward.
I bought the R3 because it looked like it was cut lower on the gum line and because my dentist said he recommends hard material for nightguard as opposed to squishy material because there is a tendency to bite and wiggle them while sleeping. I’m SO glad I bought the R3!! Within a week I was able to sleep comfortably with it all night and every night since. I’ve never had gum irritation with it and I haven’t had much for an adjustment period. It’s comfortable and I’m hopeful it can strengthen my jaw. At the very least, it’s helpful for me to quit grinding and gritting my teeth at night.
Now to see if it will fix my crowded teeth!

It has been a good investment, in my opinion!

I'm on day 3 of using reviv

I'm on day 3 of using reviv.
I have TMJ and crooked teeth due to palate collapse. I believe from braces, mouth breathing and nailbiting. I've stopped biting my nails this year, I'm practicing more mouth breathing and it's time to live without pain and hopefully - straighter teeth! Someone recommended me it on Facebook so I thought it's worth a go!
I'm only giving 4 stars now as I'd like to review again in 6 months.
I wear this at night, but I have a tendency to take it out in my sleep (I did with my retainers too. How my teeth reverted quick)
But as soon as I wake up I find it and put it straight back in. I also try to wear it and hour a day. While I get ready or do emails etc.
I can already feel the front of my pallet pushing out? And in the night when I do awake I can feel it pushing. It's actually rather therapeutic as I can feel the pain of my teeth and jaw collapsing with my TMJ so this counteracts it which is quite a releasing stretch. It aches, like when you get your braces tightened. But after a hour of waking the pain fades. Slight gum soreness but it's normal.
Loving my journey so far. Hope I keep at it!

There is a community that we give 30 days access to which talks about how to handle the irritation on gums. You dont remodel the mouth without impacting the gums. You just need to take breaks and get thru this initial difficult period.

There are hundreds of people that have posted on our community about the benefits they are seeing... so i guess there are hundreds of people that disagree with you that we are a 'scam'.

I'm a couple weeks from a FULL YEAR.

I'm a couple weeks from having worn the Reviv for a full year. I upgraded to the Reviv 2 late summer. I love my Reviv and I believe in the biomechanical theories that Ken has spent decades unraveling through his own personal journey. I have always been healthy but what changed is that my teeth have totally straightened, my gap closed, and I feel like my facial structure has improved. Also my lower back where I think I have a bulging disk, only really acts up if I help someone move or I do alot of heavy lifting, but I do think Reviv has helped my spine expand so that its not caving in on the lower back. I feel great and I am a LIFER on Reviv.

Seeing improvement in face structure

I’ve been using the Reviv mouthguard each night for the past 3 months and I’m already seeing improvements, particularily in my skin for some reason? My wrinkles seem to have smoothed out, my nasolabial folds are less prominent, more definition in my jawline, jowls gone, and my face almost looks lifted? Im assuming it has something to do with the ballooning effect? Which makes sense…inflating something would cause it to go from sagging to tightened, which would smooth out lines, and lift the face.

Needs some getting used too.

Primary purpose of my Reviv purchase was to concur snoring. I have a dental appliance for grinding. Using the Reviv was overwhelming the first day or two, but I will continue to use it.

I still have not watched the videos yet, but good sleep, overcoming snoring are a journey for me right now.

I think it'll work if I stick to it

I think it'll work if I stick to it. I have always had crowded teeth and now I floss no problem after a few months of use, and definitely see a huge shift in my lower jaw. I have severe maloclussion on one side that seems to be straightening out. I don't like the R2 but my R1 smells bad now and it's showing signs of wear. Ill keep using both and hopefully the R2 becomes more tolerable.

VERTIGO SUFFERERS SHOULD TRY

Since using Reviv (about 20 weeks) I no longer have any symptoms of vertigo; which I suffered with for decades. Sometimes severely, often just in bed when moving head position, but consistently. I think that Ken's theory about the balloon brain has merit. A chiropractor once told me vertigo was from Osteoporosis of the skullThis makes sense now.

My experience

The company maintains full transparency—Ken personally answers nearly all questions about the Reviv Mouthguard R1 and R2. Structural healing and improvement require patience and time (months). Trust the process, stay disciplined, and perform daily stretches to accelerate your progress. My personal experience with the mouthguard it helped reduce my jaw pain, improve my back posture, feet posture (improved arch), it has expanded my palate, improved my smile, and I feel less fatigued throughout the day and better mental clarity.
