It’s safe to say that a bulky, bad fitting mouthpiece can wreak havoc on an athletes’ performance.

Discomfort = Distraction. Period

Looking for the best mouth guard for MMA? If you are involved in any form of combat sport, such as MMA (mixed martial arts), you need a mouth guard that’s going to minimize or prevent head or oral injuries.

One of an athletes’ must-have protective accessories for that purpose is a custom made mouth guard.

So, what is the best mouth guard for MMA?

  • Custom made for you. Fits the athlete perfectly.
  • The correct thickness for maximum protection
  • Extends to cover the gum area and full teeth arch
  • High quality, dentist-grade material

If your budget allows, please avoid “one size fits all” types you can buy from a store. These types often are bulky, ill-fitting, and distract from the players performance.

There are several mouth guards used during sports activities


Stock mouth guards – These are over-the-counter mouth pieces and have higher chances of failing to fit. Just as the name suggests, they are stocked in the store and are the mass produced types.

Stock mouth guards are typically made with a lesser quality material that is easier to chew through or wear out.

The three most common complaints from those using these types of guards are:

  1. Inability to adapt or loose fit
  2. Wear down time – not durable or long lasting enough
  3. Bulkiness – the inability to breath, communicate & perform on a higher level.

Have you ever seen someone take a hit or fall and their mouth guard goes flying out of their mouth? This happens because the mouth guard is not properly formed to their teeth. This stock mouth guard type is simply the lowest quality and most inexpensive option.

Heat and form / boil and bite

These types of mouth guards assume the shape of your mouth when you boil and form them. They are therefore better fitting alternatives and are available in various sizes, prices and options.

Though they may fit a bit better, the plastic quality is still much lower than dentist grade material. Still, if you’re on a tight budget or in a pinch, this is an acceptable option.

Custom made mouth guards


“What is the best mouthguard for MMA?”. This is it.

A custom mouth guard offers the best fit, hence the best protection. It is designed from a model of your teeth – allowing you to comfortably breathe, eat and drink. Custom mouth guards are readily available online at affordable, discounted prices.

There are other types of high profile and low profile mouth guards, but they all fall under these three categories discussed above.

Low profile lip mouth guards – These are dual-layer design guards that protect the lower and upper lips, and feature centered airflow channels, a customized gel-fit bite surface, and high impact protection.

The best mouth guard should have the following characteristics:

  • Lets the player breathe and speak comfortably
  • Stays secure during MMA action
  • Offers complete comfort and fits perfectly
  • Is easy to clean and maintain
  • Is tasteless, odorless, tear-resistant and durable.

MMA is a full contact sport and so a mouth guard is crucial – especially a custom mouth guard, since it has all the of the features mentioned above.


Custom mouth guards for MMA are specifically designed to be able to distribute the blow throughout the head or mouth. Without this appliance, the blow affects the point of impact, causing intense pain and or injury.

A custom mouth guard for MMA has a well-built face to eliminate gagging reflexes in wearers which occurs when the inside is too thick or the guard extends too far back.

The material is well extended for tooth root protection, unlike in the boil and bite types where the material extends slightly above the teeth, providing little protection in case of a blow to the face.

A custom mouth guard for MMA is the best and most functional type of mouth guard. It is affordable and goes for roughly $100 – a cheaper price compared to the cost of replacing teeth with 2 / 3 unit bridges which may go for $1200.

This type of guard rids you of distraction, fits properly and gives you protection and safety. Okay, custom mouth guard. Got it. Now, which one?

What mouth guard Should I Buy for MMA (mixed martial arts)?

When training or participating in Mixed Martial Arts, one of the most significant pieces of equipment you should have is a combat mouth guard.

Simply put, without an appropriate mouth guard, you are more likely to end up with tooth fractures or trauma.

Whether you’re grappling or sparring, you should absolutely consider wearing a mouth guard because even a little punch or accidental hit by an elbow could break your teeth.

Teeth repair is expensive and avoidable with the right protection.

There are various mouth guards available for purchase at different shops all over the world. “One size fits all,” store-bought mouth guards exist at places like DICK’S Sporting Goods for less than $20. But do the cheaper guards offer adequate protection?

Some dentists are selling custom athletic mouth guards for $300+.

Making a decision on which mouth guard to purchase can be a daunting task because different materials, sizes and designs exist. We’re here to make it easy – your one stop mouth guard shop.

Your step-by-step guide to finding the most comfortable mouth guard available

What mouthguard should I buy for MMA? To answer this question, customized mouth guards have consistently been recommended by industry professionals as the most comfortable for your Mixed Martial Arts sport.

The company you choose for ordering your customized mouth guard determines the quality and type of the equipment you get.

How to clean your mouth guard

Taking care of your new athletic mouth guard

Once you get your new mouth guard, you need to take care of it.

A mouth guard is a breeding ground for bacteria. Don’t throw your saliva-soaked mouth guard into the bottom of your gym bag until your next training session.

When you get home, take a soft tooth brush & squirt a bit of mild soap on the tooth brush. We use Dr. Bronner’s Castile peppermint soap. You can dilute with water, and one bottle will last a long time. Plus, the peppermint smell is a nice bonus! Rinse and dry thoroughly. Store the mouth guard in your case.

So, what’s not to love about our services?
