Mouth Guard for Boxing/MMA FAQ

Custom Fit or boil and bite guard?

A custom-fit mouthguard gives a tighter fit with increased protection. Though it is slightly more expensive, it won’t fall out in use, and you can breathe and speak with it.

A boil and bite mouthguard is the more common choice and cheaper than custom mouth guards. These require you to follow a molding process in the comfort of your own home.

We’ve written an article on how to mold your new mouthguard at home. Or if you prefer, you can check out the video below.

With more styles and colors available, they are quick and easy choices. But, if the instructions for boiling aren’t followed, you may have fitting problems. Most mouthguards can be reboiled, so don’t beat yourself up too much if you get it wrong the first time.

What to consider when looking for a mouthguard?

Several important factors to consider when choosing a mouthguard include:

  • Fit – whether to go for a custom fit or boil & bite
  • Comfort – whether you can speak and breathe easily whilst wearing it. As well as, whether it fits securely and the amount of coverage the mouth guard offers
  • Materials used – some people will be after a specific material. Others will need to make sure that it’s compliant with safety regulations for their sport
  • The type of activity your mouthguard is suited to
  • Mouthguard case – Does it come with one? If not, how much is it to buy one?

How to get maximum protection?

The best mouth guards for boxing and MMA will provide the most protection if you ensure it’s fitted right:

  • Mouthguards should not make you gag
  • You should not have to bite or clench them to keep them in your mouth
  • They should fit over part of your gums
  • They shouldn’t interfere with your breathing or speech

It’s also good to be aware of the amount of dental warranty each mouthguard offers. Some that we’ve written about on our list haven’t stated the amount.

SISU’s mouthguards come with a $35,000 dental warranty for the first year. You can purchase this product here.

Is it essential to wear a mouthguard?

It is necessary to wear a mouthguard if you are sparring or in a professional fight. In fact, the ref wouldn’t let the fight start without seeing your boxing mouthguard.

It’s not essential to wear a mouthguard when training on Muay Thai bags. But, it’s a crucial piece of kit that you should always carry in your gym bag.

The damage that can result when not wearing a mouthguard isn’t only painful but also costly. This is why we always say to use a mouthguard, not just to protect your teeth, but also your wallet!

What is the best way to clean a mouthguard?

For best practice, make an effort to clean your mouthguard after each use. Then, you can store it away until its next use:

  • Rinse it thoroughly with cold water and a mouth wash solution
  • Clean the mouthguard with a soft toothbrush and a little toothpaste before rinsing it 
  • Dry it delicately with a soft cloth or paper towel
  • Place the mouth guard in its case or purpose-built container to store away safely

In Summary

Hunting for the best mouthguard for MMA or boxing isn’t easy. There are so many to pick from so how do you know which is best. To be honest, any of the models that we reviewed above are great and will give you protection.

Our winner of the best boxing mouthguard was the Venum Challenger mouthguard. With the SISU Aero mouthguard finishing in second place.
For the cheapest option, we’d go for the Sanabul all sports mouthguard. But, spending $5-10 more is worth it when it comes to your health and safety prevention.
