Instant Custom Fit Moldable Mouth Guard, Dentist Level, Clear/Gold

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 was absolutely shocked at how well this mouth guard turned out fitting! It feels like a lab made mouth guard but at a fraction of the price! Follow the instructions, take your time, and you will be pleased with the end results! It stays locked in to my teeth during bag work and sparring. I can breathe perfectly with it in and I love how soft and smooth the bottom of it feels. I'll definitely be buying more mouth guards from Opro in the future!

My high school football player remarked it’s the best fit he’s had for a mouthguard yet. He’s had boil to fit and use straight from the package ones for several years, and was always uncomfortable with them. His level of comfort was instant after we molded, it cooled and tried wearing again. Also, super fast and easy to boil and mold.

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.

Update: vegas is hot and it melted in the vegas heat. Not usable or remoldable. Still bought another one lmao 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.

It failed 2 times for my bite. I have a slight underbite and shifted jaw. This device and system doesn't account for that and made it fit worse because it only molds the top of your bite. As a result of following directions and not molding the bottom it consistently fitted poorly for me shifting my jaw. Returned for a guard the molds both top and bottoms.

Nice mouth piece. Molds well, fits well and doesn’t wear down like other mouth pieces when you clench a lot. Don’t know what material it is but if you’re getting a mouth piece look no further.

I purchased this mouthguard for my son for football and made sure we followed the fitting instructions carefully. It seemed to fit securely and properly, so initially we were happy with it. Unfortunately, during a game he was tackled and the mouthguard popped completely out of his mouth. It was then stepped on by another player and **tore into two pieces**. I understand that no mouthguard is indestructible, especially in football, but for a product advertised as a “dentist level” impact mouthguard designed specifically for contact sports, I expected it to hold up much better than this. It was especially disappointing considering it had been properly fitted and hadn't been used very long. For the price and the claims made about durability and protection, I expected something that could withstand normal football-game conditions. I wouldn't purchase this particular mouthguard again.

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!

Das ist wirklich ein heftiger Mundschutz. Der erste Versuch hat kein gutes Ergebnis gebracht aber habs direkt nach bissl abkühlzeit erneut versucht (dieses mal beim beißen auch ein vakkum „gesaugt“ und der sitzt wie wortwörtlich angegossen! Der Preis ist hoch aber absolut wert👍🏽 wie vom Zahnarzt gemacht

Bad fit doesnt fit as promised

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.
