Are you wondering what the best MMA mouthguards are?

In this article, we’ll dive into the 3 absolute best MMA mouthguards on the market in 2023 and beyond, explaining what makes them better than other mouthguards and looking at any cons.

Best MMA Mouthguards

While there are hundreds of mouthguards for MMA and combat sports on the market, we’ve done the research and present here the 3 best MMA mouthguards to save you the trouble of reading through dozens of product descriptions – most of which aren’t MMA or combat sport specific mouthguards.

The following MMA mouthguards are ranked starting with the best.

1. Best MMA Mouthguard Overall (Custom Made)

Impact Custom Professional MMA/Boxing/Muay Thai Mouthguard

  • PERFECT-FIT MOUTHGUARD – Get a 100% perfect fitting mouthguard…
  • DESIGNED FOR – These sports mouthguards are thicker than those…
  • BREATHE EASY, SPEAK CLEARLY– Our breathable mouthguards are…

>Custom-made to ensure the perfect fit

>Thicker than non-MMA specific mouthguards for unrivaled protection

>Suction effect on the teeth for zero shifting and maximum comfort

Made first available in 2015, Impact Custom Professional is specifically made for MMA and combat sports and is thicker than general mouthguards designed for use in American football, rugby, and other contact sports. 

Each Impact MMA mouthguard is 6 to 7mm thick, whereas non-MMA mouthguards are around 3 to 4 mm.

Impact understands MMA mouthguards need to be thicker and more protective because of the direct strikes to the chin and mouth area, and especially because of accidental headbutts – where general mouthguards just don’t cut it.

The Impact Custom Professional is also the best MMA mouthguard on the market because they send a teeth impression kit to your home with paid-for delivery to their dental lab, where they design the perfect fitting mouthguard based on the teeth impression you send them.

This is cheaper than going to a dentist for a dental impression and having them make you a custom-made mouthguard with their manufacturer. Impact also has a very easy-to-follow instructional video.

As the Impact mouthguard is based on each person’s teeth impression, it has a suction effect on the teeth which other MMA mouthguards don’t have. This helps it fit perfectly which means it’s very comfortable and has no gagging.

The Impact mouthguard is designed to allow optimal oxygen flow through proper ventilation, enabling athletes to speak, communicate, and easily drink water while wearing the mouthguard.

If you want or need to order a second mouthguard, Impact keeps your dental impression and can send you another perfectly fitted mouthguard very fast, rather than having to go through another dental impression process.

The Impact Custom Professional mouthguard also comes in around 20 colors and styles, including American, Irish, and Mexican colors.

The only problem with the Impact MMA mouthguard is the delivery can take longer than other mouthguards, and their communication can at times be lacking. Having said that, their customer service is top-notch when it comes to making any changes to the mouthguard if needed.

However, both of these minor problems are not related to the quality of the product. They’re also far outweighed by the superior product you get, which provides unmatched protection when sparring or competing in MMA or any combat sport.

Supporting this is the 106 reviews on Amazon, 83% of which are 5-star – the highest of any mouthguard on the market.

And while the Impact Custom Professional MMA Mouthguard is $94, it’s worth it if you came looking for the best MMA mouthguard. It stops you from going to the dentist with teeth issues or buying another mouthguard for a very long time.

2. Best MMA Mouthguard Used by UFC Fighters

>The UFC’s official mouthguard partner – used by UFC Fighters

>Patented triple-layer compression cage for optimal protection

>Youth and adult sizes available

Despite Venum being the UFC’s official outfitting partner, the mouthguards they sell and give their fighters to use are designed by OPRO, who also supply USA Wrestling and USA Taekwondo – which tells you the quality of the OPRO Instant Custom-Fit Mouth Guard.

UFC and professional MMA fighters have no interest in using sub-par products when it comes to a mouthguard because protecting their teeth, tongue, and jawline is especially important if they want to continue training and fighting year-round.

Only recently made available in May 2022, the OPRO Instant Custom-Fit Mouth Guard is the brand’s best mouthguard based on years of research and customer feedback since its founding in 1997.

While this isn’t a custom-made mouthguard, it comes with Impact’s patented compression cage (made with hyperflex technology) which you put the guard into and it molds the perfect fit of your jaw and mouth. 

This essentially gives you a custom-made fit like going to the dentist for a dental impression, at a fraction of the price.

The mouthguard has a triple-layer construction to completely dissipate shockwaves after impact. This works alongside the self-impression fin technology inside which uses ultra hi-flow gel to mold around the contours of the teeth for a great and instant fit with excellent comfort.

The suction is so impressive that it can require some effort to pull the mouthguard out. It also doesn’t protrude the lip which makes it very comfortable.

The OPRO Instant Mouthguard comes in a youth size which is up to 10 years old, and an adult size which is 10+. The mouthguard comes in 16 colors and also a UFC 30 Years edition, the newest addition.

With a 4.5 star average over 311 Amazon reviews, 73% of which are 5-star, the OPRO Instant Custom-Fit Mouth Guard is one of the best MMA mouthguards on the market in 2023. 

For the price of $39.99, you can wear the same MMA mouthguard worn by UFC fighters for training and competition.

3. Best MMA Mouthguard on a Budget

Venum Challenger Mouthguard

Venum Challenger Mouthguard – Red/Black
  • Nexfit Gel Frame for a better adjustment and comfort
  • Advanced design for an optimal breathing during the fight
  • High Density Rubber Frame for a better shock management and…

>Unique Nextfil gel frame for excellent comfort

>Available in 13 colors and comes with a protective case

> High-density rubber frame on the outside for shock dissipation

Venum is one of the top MMA gear brands on the market, and the Venum Challenger Mouthguard is a great example of why. First made available in 2013, it has stood the test of time and at just $14 it’s an absolute steal.

The first thing you may notice about the Venum Challenger Mouthguard is it’s fairly bulky. Combined with its Nextfit gel frame on the inside for great comfort and a high-density rubber frame on the outside, it first and foremost provides exceptional protection for training and competing in MMA and combat sports.

However, it still manages to be one of the most comfortable MMA mouthguards which can be put in and forgotten about almost instantly. It doesn’t restrict breathing in any way because it’s been contoured with fighters in mind – who require peak cardiovascular endurance and optimal breathing.

It comes in 13 different colors and unlike other mouthguards, the Venum Challenger Mouthguard also comes with its own protective case for maximum hygiene.

And while this mouthguard is considered a budget option at only $14, it’s far superior to a majority of the mouthguards on the market, especially if you’re looking for the best MMA mouthguards. 

Supporting this, it has nearly 18,000 Amazon reviews with a 4.4-star rating overall, 71% of which are 5-star.

The Venum Challenger Mouthguard is best avoided for those with a larger mouth/jaw as it comes in only one size and the fit is on the smaller side. It’s an especially great fit for young teenagers between the ages of 11 to 18, and adults with a small or medium-sized jaw/mouth.

Conclusion and Other Options

The Impact Custom Professional MMA Mouthguard, OPRO Instant Custom-Fit Mouth Guard, and the Venum Challenger Mouthguard are the 3 best Mouthguards for MMA on the market.

There are other great options but they don’t match the quality, comfort, fit, protection, breathability, and overall package that the above three offer. 

Many of the best MMA mouthguards promoted by others aren’t combat sports specific, whereas these three are perfect for MMA and other combat sports such as boxing, Bjj, taekwondo, wrestling, and more.
