- OPRO Instant Custom Fit Moldable Mouth Guard (Black/White) Dentist Level Impact Mouth Guard for Sports Adult – Boxing Mouthguard for MMA, Self-Fit Sports Mouthguards for Hockey – Includes Case

I purchased this brand twice, I lost the first one but it fits great. I had the first one for more than 4 years so it’s pretty durable. Once it’s molded to your teeth it’s a comfortable fit for a good price.

Thinner fit than most, which makes it easier to speak while wearing. Seems to be strong

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.

Top of the line mouth guard in the industry. Easy to use and VERY durable!

Easy to fit perfect! Tough holds shape not too bulky

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.

THis is a great product. IT was easy to set up. I use it for teeth protection when I weight lift and it works perfectly.

I’ve been training in martial arts for 23 years and have been teaching for 15 years so honest opinion of the OPRO Mouth Piece. This has great cushioning to protect the jaw and teeth on impact from medium to hard contact to jaw and chin. If you’re looking for more cushion protection and impact absorbing mouth guard this is a good fit. My own experience of training comes from Boxing, American Kickboxing, Muay Thai, Wrestling, Taekwondo, Krav Maga and various forms of Fire Arms training (Shooting to Pressure Testing scenarios with Simunation Rounds). So, the impact to jaw or chin can vary for each of those systems based on what the drill or session is. For me personally I also like when the mouth guard can clip onto my upper teeth such as a custom dentist mouth guard or Shock Doctor Trash Talker. That being said I use different mouth pieces depending on what I am doing. When training students I typically use the Shock Doctor Trash Talker Mouth Piece since it has slimmer profile, clips right on to my upper teeth and I can speak clearly to my students without it falling out, or when grappling in class or in a firearms hand to hand combatives course. Since I’m not so worried that students will land any shots on my head area due to level of ability compared to mine or don’t have to worry about it falling out while rolling with another guy retaining my training firearm or attempting to take the other guy’s training firearm. However, when competing or training with competitors/Instructors at my level in a striking discipline such as Muay Thai, Kickboxing or MMA, I use my dentist mouth guard or when traveling I’ll be using this OPRO mouth guard as a back up. Since it offers more cushion protection from head strikes that can happen when training or competing with others at my level of ability. Overall not mind blown from this mouth guard but not dissatisfied from it. Will give it a few sparring and grappling rounds to see how it holds up and keeps up with what I do. If anything it’s going to be a back up mouth guard. Since I always recommend to students and professionals to have 2-3 mouth guards when traveling or training at your home academy. And depending on the amount of use you put them through, change them out every 6-12 months or so.

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

Perfect, don’t waist money on others this should be in every sports store!

Parfait ! Process très bien expliqué et efficace quand on le suit à la lettre. Top pour de la boxe anglaise Esthétique très sympa

Très bonne qualité Permet d’épouser parfaitement la forme des dents et du palais pour permettre une bonne respiration
