OPRO Instant Custom-Fit Mouthguard – Dentist Level Gum Shield Adult and Kids – OPRO Mouth Guard Boxing and MMA, Self-Fit Gum Shield Rugby – Maximum Protection with Dental Warranty (Clear/White)

great quality mouthguard Dental fit seems to be good as advertised used in sparring multiple times, saved my jaw more than once and comfortable doesn’t fall out of your teeth because of the dental fit while still not taking up all the space in your mouth

This guard is EXTREMELY HIGH QUALITY, outer material is a very sturdy yet soft rubber type material, inside molding material is amazingly strong and provides great support and protection even when clinching down rather hard. Getting initial molding done is very simple and the outer molding brackets almost makes it fool proof. The fit and finish of final product is professional level. Highly recommend for anybody participating in a combat sport or any other sport needing teeth and gum protection. Nice storage case provided.

Very easy to follow instructional videos! And the fit was perfect! It felt as custom fitted as it can get without the actual custom fitting process and price. I’ve tried many other brands through out the years, even some more expensive than this one and those still couldn’t compare. What I love the most is the compact feel of it. It is very minimal in thickness yet protects better than any of the self molding mouthguards. When your mouth is closed you barely notice you have the mouthguard in. You can speak almost as normal as if you weren’t wearing it. I ordered 2 as always just incase I made mistake but both came out perfect. One thing I highly recommend doing so that it fits even more snug around your teeth, is swishing around very cold water in your mouth before taking the mouthguard out after the 1 minute of molding while it’s hot. While your swishing around cold water in your mouth keep biting down on the mouthguard. Do it 3 or 4 times with in a minute. Essentially what that does is that the cold water will constrict and tighten the mouthguard around your teeth because of the changing temperature from hot to very cold. Many put the mouthguard in cold water when taking it out after the 1 minute hot molding process which is what has always been done since forever. But you have to remember the cold water constricts and tightens it ever so slightly. So when done outside of your mouth it might even tighten and shrink a little too much to the point where there forms a small gap between the floor of the mouthguard and your teeth. Overall the best mouthguard I’ve tried in sparring. Getting hit with it on let me feel how cushioned and protected my teeth were on impact.

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.

This is hands down the worst designed "custom-fit" mouth guard. The molding instructions are clear, however if you follow them and use the compression cage the mouth guard will fold over on itself during the molding process and immediately ruin your mouth guard. You are better off going to Dick's and buying a boil and bite mouth guard for little league football. I've never given a review like this if that says anything.

Molding was a breeze and protective of teeth and jaw for muay thai sparring

I started boxing and with all of the other stuff I needed getting a dentist fitted mouthguard wasn’t in the budget. I read a lot of reviews and gave this one a shot. If you follow the directions you will get something right at or a notch below dentist fitted. Pro’s: using the kit I was able to get a mouth guard that I have to pull out with my fingers. It will not come out on its own. I’ve been punched in the mouth a few times and didn’t feel anything as far as my teeth are concerned. The directions were straight forward and the mouthguard fits great. Only took one boxing session to get it to the point where it was comfortable and unnoticeable to wear. Cons: there was a sharp corner on the inside upper of my mouth. I was able to gently sand it with a dremel tool and make it disappear. I would consider that finish work and something that may need to be done with any mouthguard. It was uncomfortable the first time I wore it, but after that it’s been something I don’t even notice once it’s in place. Conclusion and notes: one thing I did when it was molding in my mouth is to push inwards onto the mouth guard and assist the tray system in applying pressure inwards to get a precision fit. I haven’t don’t this without that technique, so I can’t say if that aided in the tight fit I got or if it made no difference. It was actually such a tight fit at first I thought it was stuck in my mouth until I figured out which direction to pull to remove it. After using this a couple times, I’ve scrapped future plans of getting a dentist fitted mouthguard and will be buying another of these when the time comes. If you don’t chew on your mouth guards, I’d expect this to last a year or more.

I like it a lot. Nice and snug. Not too bulky. Directions are easy. I HATE wearing mouth guards but this one is the most bearable one I’ve tried.

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

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

Ich trage diesen Mundschutz nun schon seit ein paar Monaten mindestens dreimal die Woche beim Training. Davor hatte ich diverse andere Modelle zum selber anpassen und auch drei Jahre lang einen Mundschutz vom Zahnarzt. Ich finde sogar, dass dieser Opro Mundschutz besser sitzt, als der vom Zahnarzt angepasste. Das liegt vor allen Dingen daran, dass er einfach fest im Mund sitzt. Ich muss ihn wirklich mit zwei Händen rausziehen. Deshalb sitzt er beim Training auch bombenfest und stört nicht. Ich werde keinen anderen Mundschutz mehr kaufen.

Emprunte facile à réaliser avec une notice claire et simple. Il se maintient vraiment bien en place sans avoir à le retailler, avec un bon confort.
