The best mouthguards for boxing, MMA, and Muay Thai 2022

Do you want to hear something I heard recently?

I heard someone say that boxers and combat sports athletes who say mouthguards are not necessary are usually the ones who have not taken a strong hit to the mouth.

One headbutt or elbow to the mouth is usually enough to convince any athlete of the value of wearing a mouthguard.

Fact: If you box, grapple or spar long enough, it is not a question of if you will get hit, but when.

In this short guide I will discuss how mouthguards work, what they actually protect, go over the different styles and customization options, and finish of with a review of 10 of the best boxing mouthguards and best mouthguard for MMA

What Specifically Do Mouthguards Protect?

Some skeptics may say that mouthguards don’t help prevent injury, and while they can not prevent every type of injury, they do offer protection.

Mouthguards prevent many types of sports related dental injury.

This study stresses the importance of wearing a mouthguard while boxing and blames the absence of a mouthguard on lateral luxation of one amateur boxing.

Lateral luxation is displacement of the tooth and damage to or fracture of the bone holding the tooth in.

  • Prevent top and bottom teeth from slamming into each other and chipping.
  • Prevents lateral luxation – movement or the tooth and damage or fracture to underlying bone.
  • Prevent broken teeth by dispersing shock among all teeth instead of a few.
  • Prevent severe cuts to the inner cheek and tongue by covering and creating a smooth surface around the teeth.

What Mouthguards Can Not Do?

Mouthguards can not prevent concussions. A concussion is causes by the rapid movement of the head in one direction, as would happen with a hit, kick, knee or elbow to the face.

The rapid movement causes the brain to slam into the skull, which is what causes a concussion, and a mouthguard can not stop this.

Should I Go for a Double or Single Mouthguard?

The truth is the majority of boxers and contact sports athletes wear a single sided mouthguard worn on the top teeth.

While conventional wisdom may say that a double is more protective, there are several reasons doubles are not commonly worn.

Let’s review the pros and cons of each style.

Double Sided Mouthguards

  • This style trains you to keep your mouth closed at all times, because that is how they are held in. This reportedly helps prevent jaw injury.
  • Protects both lower and upper teeth at the same time.
  • Double sided mouthguards are very hard to breathe through.
  • You absolutely can not talk or drink water while wearing a double sided mouthguard.

Single Sided Mouth Guards

  • More comfortable than a double.
  • Can talk, breathe and drink water while wearing.
  • Does not force you to keep your mouth closed- a closed mouth is known to help prevent injury, just like keeping your chin down and guard up.

Boil and Bite, Custom Fit or One that You Wear Right out of the Package?

What is Better?

The most common style available are boil and bite styles, where you place the mouthguard in a little hot water and mold it to your teeth which can be done from home.

Man say custom mouthguards are the only way to go but these are expensive and usually require a trip to a specialists.

There is one mouthguard in my reviews below that is a custom style you can do from home so be sure to check that out.

Boil and Bite

These guards are made with heat sensitive material that becomes soft in hot water. You generally need to boil water, place the mouthguard in the hot water for a set period of time, remove the guard and place it in your mouth to complete the mold.

These offer a good custom fit, but not quite as form fitting as custom made guards.

Custom Style

This style involves making a cast mold of your teeth. The dentist or professional uses the mold to make an identical form of your teeth for a mouthguard that fits perfectly.

This style is more expensive and takes longer t receive. Usually a visit to the dentist is necessary, but the impact mouthguard listed below can be ordered and molded from home, and you then mail the mold back to the company who then manufactures the mouthguard and sends it back to you, all for under 100 dollars.

Out of The Box-Off the Shelf Style

This style is common in big box stores and sporting goods stores.

They are the easiest to find and usually the least expensive, but they often have a crappy fit. A custom or boil and bite style is preferred.

What is the Best Way to Clean a Mouthguard?

  • Rinse it with some warm water.
  • Lightly brush it with your toothbrush (don’t use toothpaste!).
  • Allow it to dry.
  • Put it back in its case.

Warning: Don’t Use toothpaste. It is too harsh on the material mouthguards are made of and can break them down.

For deep cleanings you can soak the guard in denture cleaner for 20 to 30 minutes before rinsing and drying.
