Nunawave Oral Care Pro – just how flexible is the mouthguard?

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.

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.

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.

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.

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.
