Mouth Guard for Boxing/MMA FAQ

Custom Fit or boil and bite guard?

A custom mouthguard offers a more personalized fit and increased protection for your teeth and head. Though it is slightly more expensive, it won’t fall out in use, and you can breathe and speak with it in. 

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 fit your new mouthguard at home. You can read it here, or if you prefer, you can check out the video below.

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

What to consider when looking for a mouthguard?

Several important factors to consider when choosing a mouthguard include:

  • Your personal style – whether to go for a custom fit or boil & bite
  • The comfort of the mouthguard in use – including whether you can speak and breathe easily, whether it fits securely and the amount of coverage the mouth guard offers
  • The materials the mouthguard is made up from – and whether it’s compliant with safety regulations
  • The type of activity your mouthguard is suited to
  • The mouth guard case your model comes with – this will ensure it remains protected when not in use

How to get maximum protection?

The best mouth guards for boxing, and indeed all other contact sports or training, will work to provide maximum protection if you ensure they’re fitted correctly:

  • 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, you can purchase this product on Amazon.

Is it essential to wear a mouthguard?

It is absolutely 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.

Though it’s not essential to wear a mouthguard when you are training on the bags, it’s a crucial piece of kit that 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 advise using a mouthguard, not just to protect your teeth, but also your wallet!

What is the best way to clean a mouthguard?

For best practice, after each use, make a concentrated effort to clean your mouth guard fully before storing it away until its next use:

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


Whether you’re after the best mouthguards for MMA, or you want to protect your mouth during regular workouts and sparring sessions, having this kind of added protection is highly recommended.

To remind you, 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 advise you to go with the Sanabul all sports mouthguard. But splashing out an extra $5-10 is definitely worth it when it comes to preventing concussions and protecting your teeth.
