"Seven months ago, I was afraid to smile in pictures." Tommy found the 80 USD R3.
Seven months ago. He hated how his smile looked in photos. A friend told him to wear a mouth guard as much as possible. "And I thought, huh, was he wrong?"
The price. "I didn't have $5,000 to spend on braces." He went with the R3 at 80 USD.
The fit. He had the first Reviv, "but it was kind of too big for my mouth." The R3: "it fits perfectly in my mouth."
His routine. Out of the case at bedtime, back in the case in the morning. "So simple, so easy to use." His experience, not a promise.

"You probably sleep with your mouth open."
- 3
Skeptical?
"I was very skeptical of this Reviv mouth guard, until I saw my old functional therapist talking about it."
The R3, the guard Tommy wears every night
Worn while you sleep
Overnight, plus a few daytime hours if you want to move faster. No routine to learn.
Gentle, steady pressure
The flat-plane design supports the jaw without locking your bite, so it can settle where it should.
Ready out of the case
Premium flat silicone, food-grade tested. Ready out of the box, nothing to prepare. Backed by a 1-year warranty.
How did the R3 help Tommy?
What he comes back to in his clips. His experience, not a promise.
Smiling in photos again
"Not only it had an amazing result with my teeth and my jawline..."
Better sleep
"...but I've been able to get much better sleep."
It fits
"It fits perfectly in my mouth. And I can close it and sleep so good."
Three steps. All of them easy.
Take it out of the box and wash it
Wear it to sleep and 2–3 hours during the day
Wash it and let it dry
Confused about size? Measure your width.
One measurement decides it: the width across your back molars.
Width · molar to molar
| Size | Width, molar to molar |
|---|---|
| Medium | 50 to 62 mm |
| Large | 63 to 72.4 mm |
| XL | 72.5 mm or more |
Tips: use a crisp, firm apple, make sure your teeth are clean and dry, press down evenly, and measure carefully in millimetres. No apple? Cut a piece of cardboard to the shape of your upper arch, or measure the width of a current retainer.
Need help on how to measure?
Watch how to measure your palate size with the simple bite-and-bread method:
Consistency is the whole game
- Weeks 1-2: the adjustment phase. A little soreness or extra saliva is normal, your soft tissue is adapting, not a sign anything's wrong.
- Build up gradually: shorter daytime sessions first, then overnights. Ease off for a bit if it ever gets sharp.
- Over the weeks: Tommy talks about seven months of wearing it as much as he can, smiling in photos again and sleeping better. What he describes is his own experience, not a promise.
What people say about the R3
Questions, answered
How should I start? ›
Wearing it: the standard pattern is overnight plus 2 to 3 hours during the day. Build up gradually with shorter daytime intervals first. The early phase is the hardest and gets much easier after a few weeks.
Early discomfort: sore teeth, achy gums and extra saliva in the first weeks are the soft tissue adjusting, not a problem. Take breaks if it gets sharp, don't push through pain.
Faster results: consistency first, then simple stretches like Bite and Hold alongside the guard.
How does sizing work? ›
Width matters most. Measure the outer edges of your upper molars at their widest point, shown in this size guide.
Medium fits a width of 50 to 62 mm, Large fits 63 to 72.4 mm, and XL is for 72.5 mm or more.
Why does it work? ›
Think of the soft tissue over the skull like a balloon. Grinding your teeth down deflates it over time, what we tend to call "aging." Adding height back with gentle, consistent pressure runs the same physics in reverse.
How many people have done this? ›
Over 30,000 people have started using Reviv appliances and this method.
What is it made of, and what's included? ›
Premium soft silicone, food-grade tested. Your order is the R3 in your chosen size and colour, with its storage case and instructions, backed by a 1-year warranty.
