Hi,

A few hours in is very early, so let's clarify a couple of things before jumping to XL.

Being able to fully close your mouth easily isn't necessarily a sign it's too small, that's actually the goal over time as things adjust, so early ease of closing isn't concerning.

On "a lot of movement" and "not secure", this is pretty common in just the first few hours/days, and it's almost always because the soft tissue hasn't stretched enough yet to hold the guard passively in place, not a sizing issue. The real test is whether your teeth seat into the channels properly when you first bite down. If they do, large is likely correct.

Give it more time (days to weeks, not hours) and it should start feeling more secure as things stretch. Mouth tape can help support it staying in place in the meantime. We wouldn't recommend jumping to XL based on movement/looseness this early on, that's a very different pattern from a genuine width issue.

Hi Rachel,

Thanks for your email.

We recommend to double-check your exact measurement using the bread test: bite into a piece of bread and measure the bite mark at its widest point (outer edge to outer edge of your upper molars). Here's the tutorial: https://www.youtube.com/watch?v=gmoeX-6gsFg

If your measurement is between 63-72.4mm, you'd fit into a Large. If it's 72.4mm or above, you'd fit into an XL.

We can send a different size for $15 and no need to send back the one you have.

For the size change please email cs@getreviv.com with your order# and what size you want.

There's no model built specifically for speed. In our view, the biggest lever for faster progress is wear time and technique, not the model itself. That means building up to consistent daytime wear (not just nights) and stretching a lot (eg. yoga, thumbpulling, our 'fast method' etc)

On model choice: R3 is our default recommendation for most people; it's cut lower (easier on the gums) and made for durability. R1 is lighter and softer if that's a better starting point. R2 sits between them in durability but has the same firmness and height as R3.

We can't promise a specific timeline or outcome, since it varies person to person.

If you want to dig into the Fast Method and hear what's worked for others, that's a good use of our community: https://www.skool.com/reviv-2885/about

Hi we'd emailed you earlier and sent a link to you. Did you see that?

We just emailed it again from cs@getreviv.com

Hi!

There's probably no major benefit to transitioning — the R2 isn't a next step. Both models work the same way and use the same firm LSR material, so the process itself is identical in either one.

The difference is the air holes. The R3 has the biggest holes, which helps with saliva flow and mouth breathing, while the R2 has smaller holes with a nose-breathing focus. The R3 is also cut a little lower, which is easier on the gums. It's the model we usually recommend to users, even if they're just starting out.

Since the R3 is working well for you, i'd stick with it for now. And focus on stretching as a way to make progress (eg. thumbpulling, yoga, etc)
