MMA Mouthguard Buying Guide

Whether you’re in the market for the best MMA custom mouthguard or just a generic one, you’ve ended up in the right place. We’ve done a lot of research on the topic and have created a guide that you should definitely check out if this is the first mouthguard you’re getting. 

Comfort and fit

This is by far the most important aspect to take into account when shopping for such an item. If you are utilizing a boil and bite mouthguard, you need to make sure that you spend the right amount of time that’s required to mold it properly, as per the dimensions of your mouth. A well-fit mouthguard can effectively mold to your teeth, and it can do so almost perfectly. 

This means that it will remain in place even during your fight and no matter the hits you receive from your opponent. The fit needs to be tight, but you should always opt for the right balance of protection and comfort.


This is the second most important aspect when you’re looking for a dependable mouthguard for MMA. when you’re training or sparring, it’s critical that you get a mouthguard that actually fits your mouth like it is supposed to. The correct size will allow you to breathe properly, but it also matters when it comes to offering you protection.

If you end up getting a mouthguard that’s too big for your mouth, your breathing might be affected. On the other hand, if it is too small, you aren’t going to benefit from full protection.


The mouthguard should ideally fit snugly against your upper teeth, without having you needing to clench or bite the product. If you have to do this, it just doesn’t fit properly. It should never shift or fall out.

Style and design

By far the least important factor of all, the design of a mouthguard for MMA only makes it look visually appealing for one reason or the other. It’s true that some offer custom designs and even texts that you can put on your mouthguard. Just know that adding customized text to such a product will inevitably lead to you having to pay more for it. 

Boil and bite vs. custom mouthguards

By far the most common type of mouthguards available for sale these days are boil and bite ones. They are inexpensive and made of specialized material that’s made specifically to soften in water, conform under pressure, and solidify for your protection. Many fighters select this type since they’re cheap and easy to work with, and they offer good results if they are molded properly.

The advantages offered by boil and bite models are that they don’t cost a lot of money, they make for a fast and easy way to be adequately protected, and they also come in a variety of designs and styles. Their drawback is that they might not be able to fit properly if the instructions aren’t followed in a correct manner.

Custom-fit mouthguards, on the other hand, offer the best protection and fit, no matter if you box, practice Muay Thai, MMA, or any other contact sport. 

They are more expensive compared to their boil and bite counterparts, and it might take several weeks for the manufacturer to customize the unit and then deliver it to you. However, they fit perfectly, they offer fantastic protection, and you can speak and breathe properly since they’re made for your mouth.
