The Best Mouthguards for MMA, Boxing, and Muay Thai

Shock Doctor Gel Max

Let’s kick things off with one of the most recognizable mouthguard brands around the globe—the Shock Doctor.

This company is not only the leading manufacturer of mouthguards but also other types of protective gear such as forearm pads, cups, supporters, elbow guards, compression wraps, etc.

One example of the best mouthguards that they offer is the Shock Doctor Gel Max. In fact, it is also one of their most popular mouthguards.

A notable feature of this specific brand is its shape and molding, which perfectly fits in your mouth and prevents it from moving around or, worse, falling.

It also comes in two variances—flavored or non-flavored. And it is also available in two sizes—adult or child. But they offer a wide range of color that suits your preference.

  • It fits comfortably in your mouth
  • Excellent protection
  • Wide range of color selection

  • Cons

    • It may be too small for kids of a certain age

    Shock Doctor Max Airflow Mouth Guard

    It’s another variance of Shock Doctor that I personally like.

    Although there was no mention of MMA or any combat sports, I believe that it would still perform well in such sports to some degree.

    Aside from its amazing fitting, overall protection, and comfort level, the reason why I put them in this list is the airflow feature.

    Sparring sessions may take its toll during intense workouts, and the Shock Doctor Max Airflow Mouth Guard helps you to maximize breathing for better performance.

    In addition, it is excellent for combat sports because it also protects your lips, which would be hit often during sparring sessions.

    This piece of mouthguard is also ideal for fighters who are wearing braces.

  • Breathing channels
  • Amazing protection
  • It also protects your lips

  • Cons

    • Some people who have used the brand experienced cracking at some point during usage

    Venum Predator Mouthguard

    Venum is my favorite MMA brand. When I look for MMA gears, I specifically look for Venum first.

    What draws me to their products is the overall aesthetics and quality of apparel and MMA gears that they are manufacturing. I mean, their designs are just pleasing to look at.

    And it is for these reasons that two of their top mouthguards have made this list.

    First, let’s talk about the Venum Predator Mouthguard.

    The initial reaction that you might have upon seeing them is the design. It has a fang-like design on the front similar to its cobra logo.

    You’ll definitely gain attention once you wore them. Yes, this may be so, but what about the performance of the mouthguards?

    As aesthetic as they are, this gear offers maximum protection and comfort.

    Its rubber shell is very durable yet moldable that perfectly fits in your mouth.

    The Venum Predator Mouthguard also offers excellent shock absorption that protects you from any injuries.

    Lastly, they are a little better than the Venum Challenger because it has three layers that further strengthens overall protection.

    Venum Predator Mouthguard


  • It has three layers of rubber that offer maximum protection
  • The style of the mouthguard is boil and bite
  • Durable
  • Amazing design
  • Comfortable to wear

  • Cons

    • It may be a little bulky to some

    Venum Challenger Mouthguard

    The Venum Challenger Mouthguard is another excellent product of the French combat sports brand.

    Although not as better as the Venum Predator Mouthguards, they are still the best option if you’re aiming for overall protection and comfort.

    This particular mouthguard of Venum is specially designed to help the fighter achieve optimum breathing during sparring sessions.

    The rubber of the Venum Challenger is highly dense that offers maximum shock absorption. Having such a feature in your mouthguards reduces the risk of potential injuries.

    The fang designs of this mouthguard are not as prominent as the Predator.

    If you’re not comfortable with the designs of Predator, then you can also go for the Challenger product line. Either way, you can’t miss it.

    • Wide range of colors to choose from
    • Durable
    • It is made of high-quality materials
    • It offers great overall protection


    • You may find it hard to breathe upon the first try. But you’ll progressively adapt as time goes by

    RDX Mouthguard

    RDX is another reputable MMA brand. With this being said—you can’t go wrong with this brand as well.

    The RDX Mouthguard has a boil and bites design. What this means is that such a feature allows perfect fit when worn by the fighter.

    Another notable feature of this brand is the Tri-Flow Technology that enables optimum breathability even under intense sparring sessions.

    It can also handle high-level impacts that reduce the likelihood of injuries during training.

    Everlast Evershield Double Mouthguard

    Impacts are an inherent part of combat sports. And, commonly, some of those punches may land in the area.

    With this being said—it is important to take proper measures to reduce potential injuries.

    The Everlast Evershield Double Mouthguard lives up to its name—the brand is ever-reliable in shielding your mouth from high-level impacts that may occur during sparring workouts.

    This particular combat sports gear is heavy-duty. Therefore, you can also rely on them for long-term use.

    It is also a double mouthguard that protects both the upper and lower jaw.

    Despite these protective features and its durability, the Everlast Evershield Double Mouthguard is comfortable to wear.

    • It may be a little to some wearer

    SISU Mouthguard Aero

    The SISU Mouthguard Aero is not as dense compared to other gears listed in this review, but they are definitely super comfortable.

    Also, the benefit of thinner mouthguards is that it enables you to talk during training.

    In addition, it still gives you the ability to drink and breathe easily even in times that you’re wearing them.

    Although this may be the case—rest assured that it can still give you the protection you need.

  • Extremely comfortable
  • Lightweight

    • The tiny holes on the front of the mouthguard may irritate the back area of your lips

    Buyer’s Guide

    There are several things to consider when buying a mouthguard for your training in MMA, Boxing, or Muay Thai.

    Some of these considerations include the following—


    Always refer to the size chart as you’re searching for the mouthguard that suits your preference.

    Apparently, this is important because you don’t want the mouthguard moving around as you’re training.


    The overall design of the mouth is pretty much subjective.

    For example, I mentioned earlier that I personally like the aesthetic of Venum Predator because of the fang design.

    But some may find it too flashy and may get mouthguards that are simple with plain designs.

    Another mouthguard design you have to consider is whether you prefer Boil and Bite or         Custom Fit.

    If you’re aiming for overall protection, then Custom Fit is what you might be looking for. These mouthguards offer the best protection and fit possible for fighter engaged in any type of combat sports.

    On the other hand, Boil and Bite offer a high level of protection. But most fighters select them because they are cheaper.

    Their characteristic, however, is that they tend to soften when exposed to liquids, reshapes when placed under pressure, and then it eventually solidifies.

    In either case, both designs are great and offer maximum protection.


    In terms of comfort, you again have to consider whether it’s Boil and Bite or Custom Fit.

    Each design offers different types of comfort levels, so you may have to experience both mouthguards to determine which one is more comfortable.

    Final Thoughts

    I hope my review of the best mouthguards for MMA, Boxing, and Muay Thai has provided you sufficient information in determining which brand suits your preference.

    I also hope that the buyer’s guide may help you with future purchases.

    Regardless of what brand you choose, you can never go wrong with the ones listed in this review because they are among the top mouthguards in the market.

    One final advice, though, it is better to stick with reputable brands to assure the quality of the mouthguards—always put quality over the cost.

    There are cheaper mouthguards from unknown and obscure brands, but I assure you that the quality and level of protection is incomparable as to those offered by reputable brands.

    Well, I guess that’s just about it!

    Thank you for taking time off and reading my review of the best mouthguards for combat sports!

    I hope to see you next time!
