Devin Clark Mouth Injury

In sports where people fight each other, it's pretty common for fighters to get hit in the face. That's why it's super important for them to wear protection. If you're searching for the best mouthguards for Mixed Martial ArtsBoxing, and Muay Thai, you're at the right article!

Mouthguards are really important because most hits in these sports are to the head. Wearing a mouthguard helps you protect yourself and lowers the chance of getting hurt, especially in the jaw and mouth area, including your lips, teeth, and overall mouth.

Even when you're just practicing, there's still a risk of getting injured. Things like ripped lips and gums can happen, making it tough to eat and basically stopping you from training. Plus, once your teeth are broken, they don't grow back. So, having a good mouthguard is crucial for staying safe and keeping on with your training.

That's why you often see athletes wearing mouthguards, even in non-fighting sports. When you're looking for a mouthguard in a combat sports market, there are so many brands to pick from that it might be a bit much.

If you're interested in finding the best mouthguards for fighters, especially in MMA, boxing, and Muay Thai, you're in the right spot! In this review, I'll give you a list of some of the best combat sports brands around and help you figure out which one is right for you.

Buyer's Guide

You might believe you can grab a mouthguard off the shelf easily since it's just a small thing. But it's a bit more than that. Before getting a mouthguard for your MMA, Boxing, or Muay Thai Training, there are some things to think about.

The best mouthguard needs to fit well on your teeth and be made of a material that can take hits from punches or kicks. The next sections explain this more.


For the best protection from a mouthguard, it should fit your teeth well. This means all your teeth should be covered, so the mouthguard stays in place during training.

It's crucial to prevent it from moving around. Make sure it molds to your teeth's shape, locking in perfectly to reduce the risk of oral injuries. Use the size chart to find a mouthguard that fits your preference.


Mouthguards need to be comfy, so your mouth doesn't feel stressed when you wear them. They should be soft and bendy inside, not like biting on something hard. This matters because if you can move your mouth easily, you won't have trouble breathing.

If a mouthguard doesn't fit well, it can make your jaw muscles tense and cause pain and discomfort after using it. The most comfortable mouthguards are the best choice for fighters!

Design and Construction

The design of a mouthguard is mostly a matter of personal preference. In short, a good mouthguard should be made of strong material to avoid tearing, easy to clean, not hinder speech, and have good impact absorption to protect your teeth.

Some fighters like simple designs, but it's great to choose a mouthguard with a cool style along with the mentioned features.

There are two types of mouthguards to be aware of:

  • Custom-Fit Mouthguards: These are the best for fighters as they are made specifically for you, providing excellent protection in combat sports. Although they are more expensive, they offer the best fit and comfort.
  • Boil and Bite: These are common and can be found in sports stores. They are softened in boiling water and molded by biting down. While they still offer good protection and are cheaper, they can reshape under pressure, soften in hot liquids, and eventually harden with use.

The 3XS Triple Laminated Mouthguard from Brain-Pad, Inc. is a great option for MMA, boxing, and Muay Thai because it's built to keep your teeth, gums, and jaw safe when you're doing intense sports.

It's extra strong with three layers, so it lasts longer. The mouthguard has gel pads that help absorb and spread the impact from hits. It's really comfortable to wear, allowing you to breathe and talk easily, and it stays put when you're in the middle of the action.

This mouthguard is tough and durable, making it a reliable choice for rough sports, and it's designed to stick around for the long haul. So, if you're into combat sports, this mouthguard is a good option to make sure your mouth stays well-protected.

2. Shock Doctor Gel Max Mouthguard

Let's start by talking about one of the most well-known mouthguard brands worldwide, Shock Doctor. They not only make mouthguards but also other protective gear like forearm pads, cups, supporters, elbow guards, and compression wraps.

One of their popular mouthguards is the Shock Doctor Gel Max. What sets it apart is its design that fits well in your mouth, keeping it stable and preventing it from moving or falling out.

The Shock Doctor Gel Max has a strong exoskeletal shock frame for full mouth protection during tough impacts. It keeps your teeth secure and safeguards your cheeks and tongue.

You can choose between flavored or non-flavored options, and it comes in two sizes for adults or children. Plus, they offer a variety of colors to match your preference.

4. Shock Doctor Max Airflow Mouthguard

The Shock Doctor Max Airflow is a type of Shock Doctor that I really like. It fits well, provides good overall protection, and is comfortable. The reason I included it in this list is because of its airflow feature.

Sparring sessions are tough on the body, and during intense workouts, you might find yourself gasping for air, especially if your stamina isn't great. If you've used mouthguards before, you know they can make it hard to breathe properly, making it tough to catch your breath.

The shock doctor max airflow lets you breathe 10% more air with its well-designed breathability system. It relaxes the jaw and prevents the teeth from blocking the air channels, which is a big advantage!

It's also great for combat sports because it protects your lips, which can take hits during sparring sessions. This makes it an ideal mouthguard for fighters who wear braces.

Shock Doctor Max Airflow 


  • Excellent breathing channels
  • Reinforced outer frame for increased protection
  • Protects including lips


  • May result on being too bulky for the upper lip

5. Under Armour Gameday Elite Mouthguard

The mouthguard has a simple-to-use gel lining that fits well on your teeth and gums, making it really comfortable to wear for a long time. With its two-layer design, it gives extra good protection, keeping you safe from strong hits.

And here's a bonus: it comes with a $10,000 Dental Warranty, making you feel more confident about how well it protects you. It's made with special channels for easy breathing, which is great for doing activities without a hitch.

It fits almost everyone's bite and even has a detachable strap for a football helmet if you want to use it that way. Plus, it's made of tough 100% EVA material, so it's durable and has easy-to-use features, making it a solid choice overall.

Under Armour Gameday Elite


  • You won't feel stuffy – it lets you breathe easily.
  •  Under Armour is a trusted name in sports gear, which usually means good quality.
  • The materials are durable, so it should hold up well over time.


  • Some people might find it hard to get the perfect fit, leading to potential discomfort.

6. Venum Predator Mouthguard

I really like the Venum brand for MMA stuff. When I'm shopping for gear, I always check out their products first. What I like about them is how good their clothes and gear look, and they're made well too. The designs just look really nice.

That's why two of their best mouthguards are on my list. Let's talk about the Venum Predator Mouthguard first. The cool thing about them is the design - it looks like fangs, just like their cobra logo.

Wearing them will definitely get you noticed. But besides looking good, how well do they work? Well, these mouthguards not only look nice but also give great protection and are comfy to wear.

The rubber part is tough but molds well to fit your mouth perfectly. The Venum Predator Mouthguard also absorbs shocks really well, keeping you safe from injuries. With three layers, it gives extra protection overall.

The Venum Challenger Mouthguard is a great choice from the French combat sports brand. While it may not be as good as the Venum Predator Mouthguards, it's still your top pick for overall protection and comfort.

The rubber in the Venum Challenger is really tough, providing excellent shock absorption. This feature lowers the risk of injuries. Plus, this mouthguard is specially made to help fighters breathe well during sparring.

When it comes to looks, the fang designs on the Challenger aren't as noticeable as the Predator's. If you don't like the Predator designs, the Challenger line is a good alternative. Either way, you can't go wrong with it.

Venum Predator Mouthguard 


  • Nexfit Gel Frame
  • High Density Rubber Frame
  • Includes protective sanitary case

8. Everlast Evershield Double Mouthguard

Everlast, a well-known boxing brand with a history dating back to the early 1900s, is highly regarded for producing top-notch fight gear and equipment not only for boxing but also for other combat sports.

The Everlast Evershield Double Mouthguard, true to its name, effectively shields your mouth during intense sparring workouts. This heavy-duty piece of combat sports gear is reliable for long-term use.

What sets it apart is that it's a double mouthguard, providing protection for both the upper and lower jaw. This is unique, as many other brands only cover the upper jaw.

The mouthguard features a tough outer layer for added impact protection while maintaining a soft and comfortable interior. Considering its affordable price, it's a great value and one of the best mouthguards for fighters.

Everlast Evershield Mouthguard


  • Rigid outer shield for enhanced protection

9. Sisu Mouthguard Aero

The Sisu Mouthguard Aero may seem simple at first glance, but don't let its looks fool you – it's actually one of the top-rated mouthguards out there and even chosen by Amazon.

What sets this mouthguard apart is its convenience and comfort. It's super light, only 1.6mm thin, which is about half the thickness of regular mouthguards. It's like the go-to gear in my book.

While the SISU Mouthguard Aero isn't as complicated as other brands, it's really breathable, and you can talk or even drink with it on comfortably.

Although it's not the best choice for intense sparring or competitions because it's thin, it's packed with features that make it great for fighters, especially during training. So, you can train with mouth protection without compromising your performance

10. SafeJawz Slim Fit Mouthguard

SafeJawz is quickly becoming a popular mouthguard maker. Their products are a top pick on Amazon and highly rated.

They're known for their innovative SafeJawz Slim Fit mouthguard, which provides excellent grip and security for your jaws. Plus, their fluid technology makes sure the mouthguard fits your teeth well and stays in place perfectly.

I really like how they designed their mouthguard, especially the part they call JawSecure. It's extra padding around your back teeth, making it feel super protective when you bite down.

This helps prevent injuries to your jaw and TMJ that often come from hits on the side or from above. Also, the SafeJawz Slim Fit mouthguard can be remolded several times,

Unlike the usual boil-and-bite ones that can only be molded once. This makes it more user-friendly in the long run, and definitely one of the top choices for fighters
