10 Best Mma Mouth Guard 2025 in the United States

The Bulletproof World’s Thinnest Sports Mouth Guard is designed for athletes across various sports including MMA, boxing, and wrestling. It boasts a snug, comfortable fit due to its ultra-thin design and 3D molding technology, making it feel almost invisible when worn. This makes it particularly suitable for prolonged use during intense activities.

The mouth guard is made from high-performance thermoplastic, which contributes to its durability and chew resistance. This ensures it lasts significantly longer than typical mouth guards, and the company even offers a free replacement if you manage to chew through it, which adds value for money. Its advanced protection features, such as the FightGuard Insert and 3D CUSH PADS, help reduce the impact energy transferred to your skull, offering a higher level of safety during combat.

Additionally, the mouth guard is highly breathable, facilitating better oxygen flow to the brain and muscles, potentially enhancing performance. One notable drawback is that this specific model is not suitable for individuals with braces, although there is a separate version available for them.

It appears to be a solid choice for anyone engaged in high-impact sports looking for a combination of comfort, protection, and durability.

The SISU Aero Medium Mouthguard stands out in terms of fit, as it starts flat and can be custom-molded to your mouth up to 20 times, ensuring a perfect fit. This feature makes it especially convenient for those who may need to adjust their mouthguard frequently.

At just 1.6mm thick, it is 50% thinner than standard mouthguards, making it easier to talk, breathe, and drink while wearing it. This thin design contributes to excellent breathability and comfort during use. Furthermore, the optimized perforation pattern adds to its comfort and protection by absorbing impacts effectively. Another plus is that the mouthguard is non-toxic, free from harmful substances like BPA, BPS, latex, PVC, and phthalates. One potential drawback could be its suitability for those who prefer a thicker mouthguard for added psychological security, even if the high-tech material compensates for the reduced thickness.

In essence, the SISU Aero Medium Mouthguard is a top-quality choice for athletes involved in various sports due to its custom fit, durability, comfort, and breathability, making it particularly well-suited for MMA and other high-impact sports.

This makes it suitable for a variety of sports, including MMA, boxing, and lacrosse, as well as for teeth grinding at night. However, it’s important to note that this youth version is not compatible with braces; specific versions for braces are available separately. Another strong point is its durability, with claims of lasting four times longer than other mouthguards and a replacement guarantee if chewed through.

The mouthguard also allows for clear speech and easy breathing, enhancing performance during activities. Despite these pros, some users might find the thinness concerning in terms of protection, and fitting might require careful molding at home to ensure maximum comfort and effectiveness.
