OPRO Instant Custom-Fit Mouth Guard, Dentist-Level Comfort & Fit - Moldable Mouthguard for Football, Boxing, Rugby, MMA, BJJ, UFC Mouth Piece- Includes Mouth Guard Case (Sky Blue/White, Adult)

I got tired of off the shelf mouth guards constantly falling out during kickboxing class. I started looking into getting a fitted dental mouth guard and was ready to spend the ridiculous $120-$150 to have one made. While searching for reviews on dental mouth guards, I came across OPRO instant custom fit mouth guards. The reviews seemed promising as a possible option to try. So, after a bit of pondering I figured I’d give one a try before dumping over a $100 on a dental mouth guard. The forming process was pretty much the same as any other mouth guard, but the addition of the dual form tool made forming easier and provided a tight fit. The mouth guard basically clicks in place and stays put. It takes a little force to pop it back out, which is exactly what I was looking for. The mouth guard in the forming tool is a bit bulky, so it’s a bit awkward to get in and out of your mouth. It’s taller and thicker than the standard run of the mill mouth guards, so it covers more area and provides better protection. I am very pleased so far with this mouth guard, so I ordered another for a backup spare. If someone is looking for a great custom fit mouth guard for MMA, kickboxing or other contact sports without dumping a small fortune on a dental mouth guard, OPTO instant custom fit mouth guards are a great bang for the buck option.

Pretty good. This is my 3rd one. I love how these stay in place during grappling, kick boxing, boxing, sparring ect.

I bought the OPRO Instant Custom-Fit Mouth Guard specifically for MMA and boxing because I wanted something that felt more protective than the cheap “one size” guards, but still easy to fit at home. After a couple sessions, I’m happy with it overall it locks in well, feels sturdy, and I don’t have to constantly readjust it. Fit (the most important part) The boil-and-bite process is straightforward, but you really do need to follow the timing and bite down evenly. My first mold was wearable but not perfect. I re-did it and got a much better fit snug around my teeth without digging into my gums. Once molded correctly, it stays in place during pad work and light sparring, even when I’m breathing hard. Comfort + breathing For boxing/MMA, comfort matters because you’re wearing it while moving and getting hit. This one feels secure without being painfully tight. It’s not a super thin guard, but it’s also not a brick in your mouth. I can breathe fine through it, and while talking is limited (normal), I can still get quick words out between rounds. Protection / build quality It feels more structured than the super cheap guards. When you clench, it has that “solid” feel like it’s actually cushioning impact. I’ve taken a few clean shots while wearing it and it did its job—no jaw soreness, no shifting. Cleaning / storage I rinse it immediately after training and let it fully dry before putting it back in the case. As long as you don’t store it wet, it stays fresh and doesn’t get that nasty mouthguard smell fast. Pros • Stays put once molded correctly • Feels durable and protective for boxing/MMA • Comfortable enough to wear full rounds • Better fit than generic guards Cons / things to know • Molding takes a little practice (my second try was noticeably better) • Slightly bulky until you get used to it • Don’t rush the fit - fit = comfort + breathing Overall: If you train MMA or boxing and want a guard that feels secure and protective without going full custom dentist guard, this is a strong option. I’m giving it 4 stars only because the fit process can take a retry but once it’s molded right, it’s exactly what I needed.

Followed the instructions exactly the way it said and it’s the best fitting mouthguard I’ve ever had for MMA and BJJ. Fits perfect and I can’t remove it without my hands. Plus it doesn’t give you the gag reflex. Tried to remove it without my hands by just pushing with my lips and tongue but it’s stuck in there.

Don't have any pictures right now but it offers wonderful protection, the thickness and moldability married with the ease of use and ease of application makes the functionality of this mouthguard stellar. You can tell that it's made with love and that it is built to last to give your little fighter a comfortable feel where they can still breathe when they need their mouth open and not breathing through their nose I would definitely recommend this brand and any style that you happen to choose, I don't feel like you're going to go wrong

The listing is not clear, but this is not for individuals with braces. The packaging does have this in very small font. Unfortunately we did not notice this until after we attempted to fit. We contacted the seller, but they have said there is nothing that they would do.

Good quality

Great fit. Feels better than my custom impact

I have to say, the OPRO Instant Custom-Fit Mouth Guard is a game-changer for anyone serious about sports. When I first heard about its revolutionary fitting technology, I was intrigued but a bit skeptical. However, after experiencing it firsthand, my doubts quickly vanished. The fitting process was incredibly straightforward. Basically, you pop it in your mouth, and the mouth guard does the rest. It's designed to mold perfectly to your teeth, providing a snug fit that feels surprisingly comfortable for a product like this. I've tried other mouth guards in the past, and they've often been bulky or difficult to breathe through, but not this one.In my experience, comfort is crucial, especially for long training sessions or intense matches, and the OPRO doesn't disappoint. The comfort level is spot on, and honestly, I forgot I was wearing it at some points—no small feat considering how often I’d fuss with my old one. The protection is top-notch as well. I've taken some tough hits in rugby and hockey, and this mouth guard has held up brilliantly, giving me the confidence to play at my best without worrying about dental disasters.What also sets this mouth guard apart is its versatility. Whether you're into rugby, boxing, hockey, or MMA, it's designed to withstand the rigors of various sports, making it a versatile choice for adults and kids alike. All in all, I tend to think that the OPRO Instant Custom-Fit Mouth Guard is a worthy investment for any athlete. It's durable, comfortable, and most importantly, provides the ultimate protection you need during gameplay. I couldn't recommend it more!

This was the worst mouth guard I have ever come across. Unfortunately it will have to be binned and I will need to get a different brand. Would not recommend
