I’m thinking about trying the Nunawave Oral Care Pro but I’m a bit worried about the fit. My mouth is on the smaller side and most mouthguards feel too big. Is the material actually flexible enough to adjust? Not looking for a perfect custom fit, just something that doesn’t feel like a hockey puck.

Flexible is doing a lot of work in that product description. I tried a similar light therapy guard last year and it bent enough to get over my teeth, but it never stopped feeling like a lump of silicone sitting in my mouth. My mouth is small too, and the thing pressed against my gums in a way that got old after about twenty minutes. It did not hurt exactly, just annoying enough that I kept noticing it. If you are expecting something that molds to you like a proper night guard, this is not that. It is more like a soft tray you tolerate. Whether that counts as flexible enough depends on how much tolerance you have for stuff in your mouth.

Flexible enough to get in your mouth, sure. But it’s not going to mold to a small jaw the way a boil-and-bite would. Mine still felt bulky in the back corners after a week, so I stopped using it. If most guards feel huge to you, this probably won’t be the exception.

Mine has a bit of give to it when I push on the sides, but it’s not the squishy kind you can really reshape. I’ve got a fairly average mouth and it sits fine, though I’d guess a genuinely small jaw might still notice it. The soft edges help more than the flexibility does, in my experience.

The material has a decent amount of bend to it, so it doesn’t sit in your mouth like a solid block. I have a smaller mouth too and it felt way less bulky than the hard guards I’ve tried. It’s not going to shape itself to your teeth, but for just wearing it during a session it’s comfortable enough.

Flexible enough to wedge in, sure, but mine didn’t give me any real adjustment. I’ve got a narrow mouth and it still sat wide with the sides pressing on my cheeks. If you’re expecting it to actually conform to your jaw, it won’t.

[Mark Carrell]

I’d push back a little on the idea that flexible means it’ll fit a small mouth well. Mine bends, but it still feels like it’s sitting a bit wide in the back. It’s not a hockey puck, but I wouldn’t call it adjustable either.

Mine has some give but it’s still a mouthguard, not something you shape to your jaw. I’ve been using it about a month and it stays put fine, doesn’t rattle around. If you’re expecting it to hug a narrow mouth like a custom tray, that’s not really what this is.

[Dan T.]

The flexibility thing gets oversold on here. It bends to go in, sure, but that doesn’t mean it conforms to a smaller mouth. If fit is your main worry, this probably isn’t the one.

[DonnaD]

Mine fits okay but I wouldn’t call it adjustable in any real sense. It bends a little going in and that’s about it, so if your mouth is genuinely small it’s still going to feel like a mouthguard sitting in there. I’ve had worse, but I also wouldn’t buy it expecting it to mold to you.
