My teeth had literally straightened out. And it cost me $25.

WHAT I USE AND RECOMMEND
This is the one I highly recommend starting with. It’s affordable and lasts a long time. You can easily modify it yourself (see my video for important details on modification) and you can use this purchase as a “credit” if you want to try the more expensive ones. You can choose clear, blue or yellow for your color, and most adults will need size large. Unless you are certain you have a small palate, the large is best to start with, plus if you are an adult and you end up having to come back for a small, eventually you will want to upgrade to the large for even more expansion, so you will already have one. Also, even if it’s a bit too big, you can wear it a few hours at a time and keep going until it fits easier.
Best one to start with
The $25 R1 comes with 30-Days of Support
No special cleaner needed
Replace every few months or when it begins to show signs of wear
Gives you a $25 credit if you purchase R2 or R3 later
Support:
This is a Skool community where the owner of Reviv follows your progress and you’ll get to share what’s working and get advice from other community members. If you feel like you will need a little help, this would be great to invest in.
If you already know you are going to want extended support for a full year, get The Reviv [R1] Mouthguard + One Year of Support for just $100 (Far less than orthodontics and you will learn so much!)
If you want to decide later, you can add-on support later for $75 for the year, $25 quarterly or $10 monthly.
HSA/FSA discounts up to 30% available if you qualify
[R2]
$80 (or less)
This mouthguard is a firmer material, and will last up to a year, guaranteed. This one also has significantly smaller breathing holes, so if you are a mouthbreather you will want to start with R1. It is $80 for the R2 if you buy it initially, but if you have purchased the R1 in the past, you will get a $25 discount on it. If you have purchased two R1’s in the past, you get a $50 credit. So you can get it as low as $30. With this one, you may want to get their cleaner device as well, to keep it hygienic since it will last a year.
[R3]
$80
This is the newest model, and has extra holes to allow for saliva flow. This one is also a firmer material and is the only model to come in an XL size. The XL size is for people who desire even more palate expansion and I really see that for more advanced users. It also has the smaller breathing holes so if you need lots of airflow, get the R1.
You can get any of the mouthguards by themselves, or with support.
If you are unsure of where to start - I recommend starting with the R1 by itself and testing out the community. If you love it, you can then purchase the community piece as needed. If you already know you are totally committed to this working for you, then I recommend starting with the R1 + One Year of Support.

I had braces as a young teenager, and of course I didn't wear my retainer like I should have, and my bottom teeth became crooked in a matter of a couple of years.
Luckily my top teeth stayed fairly straight although there's definitely room for improvement there too.
So what did I do to get them straight?
I was actually trying to fix a completely different problem. Yes, my bottom teeth were a little crooked but they had been that way for so long I just figured at some point I would get Invisalign or something later.
But the bigger problem was the constant bruxism. Clenching my jaw all night, every night, which was leading to tooth pain and jaw pain. I had tried parasite cleanses, supplements, fascia release and more.
Someone recommended a squishy silicone mouthguard for bruxism, and I was skeptical because I've already tried so many, but I went ahead and tried it.
Because this particular model was super squishy, I thought maybe it would be gentler for me to bite down on than my own teeth. But after the first night, It was rubbing on my gums so badly I couldn't even keep it in for more than a few hours. Supposedly that was normal, and you're supposed to just deal with it until your gums get used to it, but I already struggled to stay asleep at night, so there was no way.
Then I began trimming it down, cutting off the parts that were rubbing. There is a bit of a learning curve there, because it’s way too easy to trim the wrong thing, or trim it too far.
But even though I got to fit much more comfortably, I quickly realized that I was just clenching down on the mouth guard at night. It wasn't actually helping the bruxism. And my jaw pain continued.
So then I thought I could trim off the parts that I was clenching down on, and that actually worked. Took me a few tries to get it right, and I went through quite a few mouth guards, perfecting it for my mouth.
Once I got it trimmed down to where I needed it, I finally had relief from the clenching. I was excited for that win.
So while I was enjoying waking up to no more jaw pain… something else crazy happened.
One morning and I noticed that one of my bottom teeth that used to jut into my mouth quite a bit, wasn't jutting in. And I also noticed that the gums on the front side of that tooth had become pretty swollen and puffy over time, and that had greatly reduced as well.
So I grabbed the mirror and looked at my bottom teeth and I was shocked to see that they were STRAIGHT.
I was absolutely mind-blown. I couldn't believe my own eyes. I had to go back and look up old pictures of my teeth, and luckily I had taken a before picture the day I began using the mouth guard, just to see if there were any changes. (I wasn't using it to straighten my teeth, but I knew that was a potential side effect and I wanted to track it just in case.)
So I found the before pictures, And I compared them to the pictures I had just taken, and sure enough, my teeth had completely shifted into being straight.
I showed my husband and he was amazed. I showed my kids and they were impressed.
I thought, holy crap! Everyone needs to know about this. So many people are spending thousands at the orthodontist, and also struggling with narrow palettes, and the after effects of retractive orthodontics, and jaw pain and all kinds of things.
To see if there was any widespread interest, I posted my before and after on Facebook expecting a handful of comments. And over the course of a few days 500 people had commented that they were interested. (Maybe one of them was you?)
But I knew that if I just gave people a link to the product, that they were likely going to hate it and never use it and never get the results.
In fact, I shared with a friend what I had used and she said “Oh I bought one of those, but it didn’t work for me.” I shared with her how to use it properly and she was excited to try it again.
I have healed from many things through natural methods - things that the doctors couldn’t fix. So when my dentist told me that I needed Invisalign and custom mouthguards to improve my bruxism (at a cost of nearly $5k) I started to research. And it was a deep rabbit-hole that I’m still in, and still learning more. In doing so I discovered that palate expansion will also fix my breathing issues (that a doctor told me I needed surgery for!) Always a student!
What can this mouthguard do?
People are using this style of mouth guard to straighten their teeth, widen their palette, and improve or eliminate Bruxism and TMJ.

Straighten your Teeth
This mouthguard puts gentle pressure on your teeth to move them back into their correct position. It's mild pressure, and you will feel the mouth guard feeling snug in some areas. This is good, because that means it's pushing on the teeth.
Also it's important to understand that traditional orthodontics rely on retraction, and pulling the teeth inward. The mouthguard works through expansion. Expanding the palate and giving the teeth room to align in their proper place.
And it straightens anything you have it on. So it will be straightening the top and bottom.
The best part is that it works while you sleep. So you can go about your day as usual. For faster results you can wear it during the day but I didn't, and you saw my crazy results in just two months.


Palate Expansion & Tongue Position (Orofacial Myofunctional Disorder)
Many people are suffering with a narrow palate. This can cause difficulty breathing through your nose for long periods of time, which means you are constantly having to breathe out of your mouth which can lead to an acidic mouth and dental decay. It also means your tongue cannot rest on the roof of your mouth properly. This causes a lot of issues in and of itself too.
The saliva is naturally alkaline and is meant to bathe the teeth while you sleep, and keep them strong, but it can't do that if the mouth is constantly open, especially at night.
Your mouth should be closed and your tongue resting on the roof of your mouth, almost suctioned up there. This provides a gentle pressure to keep your palate expanded.
But if your palate is narrow, or you have difficulty breathing through your nose, your tongue can’t do what it’s supposed to do.
Using this mouthguard can expand the palate, allow for easier nose-breathing and space for your tongue to be in its proper position. It can re-inflate the facial structure that may currently be collapsed.
Some people use harsh dental devices like MARPE and MASPE which screw into the roof of your mouth and then you slowly dial the pressure over time to expand your palate. This leads to a huge gap in your front teeth as well as making your teeth a bit crooked which requires Invisalign during or after treatment.
Using the proper mouthguard like this, in the proper way, can expand your palate slowly over time, which will allow your teeth to shift and align properly.

Help with Grinding and Bruxism Symptoms
As far as grinding and bruxism, these things can come from a myriad of issues from parasites, to stress, to misaligned teeth, so the mouth guard might not cure your grinding or bruxism, but it can definitely help with the symptoms and give you relief while you work on the root cause. Grinding on this squishy silicone will protect your teeth, and you can modify the guard to wear only in the front of your mouth to prevent your back teeth from touching at all which helps prevent clenching too.

What to expect...
Because of the way that the mouth guard is designed, when you put it in, you will notice your jaw being pulled forward slightly. It might be a little uncomfortable as those muscles and tendons begin to stretch out, but that's normal. You have to get your jaw back into the correct position.
You might also notice some teeth sensitivity. If you've ever had braces before, I'm sure you can remember when you had them tightened, and a few days after that your teeth were very sore and tender and you probably had to eat mashed potatoes or ice cream because it was impossible to bite down on anything.
When you wear the mouthguard overnight, you will wake up with slightly sensitive and sore teeth. This is a good sign! This means that they are moving. So you won't be able to bite down hard on anything usually for the first hour after you wake up. As you continue to wear the mouthguard, this sensitivity diminishes as your teeth begin to shift into place.
This may take a few weeks or a few months, depending on how quickly your teeth are shifting and how far they need to move.
FAQs
It's made of a soft yet strong silicone material. As long as you rinse it off after each use, dry it and store it in its container, It can last many months with daily use. However if you use chapstick or any facial creams with oils that might potentially get into your mouth, that can begin to degrade the silicone.
If you notice any dull or rough spots on your device, you'll want to get a new one. If you chew on the thing a lot at night, you may need to replace it monthly or every couple months.
Some people have reported closing their gaps. The mouthguard works through structurally changing your jaw and bite and aligning your teeth. This can result in closing gaps related to misaligned teeth positioning. If you have had teeth pulled or are missing teeth that resulted in a gap forming due to excess space, the mouthguard may not work for that.
It is made out of silicone. Now I'm not a big fan of plastic, and metal has its own problems too as often it has nickel in it, and so right now, silicone is fairly safe. If you're concerned about microplastics, you'll want to replace your night guard monthly. But silicone doesn't shed microplastics nearly as bad as regular plastic, and it takes a while for it to start doing that. So if you replace your guard frequently, it's not something you have to worry about.
When you first get your mouthguard there is a high likelihood that it won’t fit perfectly. And that’s because your mouth is out of alignment. The key is modification, patience and if needed you can build up to longer wear-times over time. So if it doesn’t fit perfectly - that’s normal and expected.
I know that people who are committed to the process see improvements over time. Maybe yours starts with jaw alignment and palate expansion before you notice your teeth improving. Or maybe your teeth are super crooked and need more time. My teeth got straight in just 2 months, but they were mildly crooked. Be reasonable with your expectations and don’t expect a magic pill. You might also need to work on loosening your fascia and add thumb-pulling to get more forward growth in your maxilla. But you can learn and adjust as you go.
No, not any. It will work if it has the necessary features. If it doesn’t, then it likely won’t work.
So the problem that a lot of people have is that their tongue is not resting on the roof of their mouth naturally.
This can create all kinds of issues, including crooked teeth, facial collapse, difficulty in breathing through the nose, snoring and more.
The idea with Myofunctional therapy is that you can train your tongue to sit on the roof of your mouth using exercises. Basically you will be sucking your tongue to the roof of the mouth, keeping your lips sealed, teeth slightly apart and nasal breathing. You can then do a swallowing action, to strengthen the tongue position. Having the tongue on the roof of your mouth can also provide some pressure to expand the palate very slowly over time, though this is more prevalent in children while the palate is still developing.
For me this didn’t work for two reasons. One, my palate is so narrow my tongue doesn’t fit well up there. Secondly, I can’t breathe through my nose properly so I can’t hold the exercises long enough, nor will I ever be able to.
So I need to expand my palate first, then work on keeping my tongue up where it needs to be.
And there is another drawback - time. You have to make time to do these exercises daily, some of them all day. And it doesn’t work as well for adults.
I would rather just wear a mouthguard and let it open things up for me. Call me lazy.
Now if there are speech issues, or other tongue issues, the mouthguard will not help with that. If that’s the case for you, you will want to see someone trained in solving those problems, possibly including a Myofunctional Therapist.
But if you’re looking to expand your palate, align your teeth or get some relief from TMJ/Grinding/Clenching, the mouthguard will do a quicker and better job than tongue exercises.
