Venum Challenger Mouthguard

Venum "Challenger" Mouthguard, Black/White

Even though it’s one of the many cheap BJJ mouthguards that you might not consider good enough for you to take into account, the truth is that Venum is a well-established brand that makes some of the most reliable pieces of equipment for training and fighting. The same goes for this item right here, which boasts the manufacturer’s Nexfit Gel Frame so that you can benefit from better adjustment, as well as plenty of comfort.

The design of the product is also something worth writing home about as it enables you to breathe correctly even as you’re focusing on your opponent’s moves and those of your own. The frame of the item is made out of high-density rubber, so it both offers you the right amount of protection, as well as superior shock management, but it can also stand the test of time. 

To make sure that you’re able to use it time and again and that it doesn’t come in contact with the contents of your backpack, for example, the manufacturing brand delivers this unit with its own protective case.

SISU Mouth Guards Custom Fit Sports

SISU Mouth Guards Max 2.4mm Custom Fit Sports Mouthguard for Youth/Adults

Another good BJJ mouthguard is this one by SISU. It is now available in several color combinations, and it is designed for youth or adults — depending on the size that you pick. It measures 2.4mm in thickness, which means that it is slightly thinner compared to conventional sports mouthguards. 

However, that doesn’t mean that it is any less capable of excellent performance as it offers you the best in terms of protection. Besides, the slim design makes it possible for you to communicate with your trainer or your opponent, and you can even wear this while you take a sip of your drink when you take a break.

Having been developed with the unique Diffusix technology that’s proprietary to this brand, this item distributes the impact forces from a variety of sports (soccer, hockey, football, lacrosse, as well as jiu-jitsu and contact sports). Moreover, this one comes with a wider bite pad and rounded edges, so it has most features you need to feel comfortable.

Venum Predator Mouthguard One Size

Venum Predator Mouth Guard, Black/White

Marketed as the new benchmark in this category as it can offer you the perfect mix of flexibility, fit, as well as shock absorption, the Predator model from Venum is another BJJ mouthguard to keep in mind. It is made with a dual-core design, which means that it first absorbs the powerful part of the shock and then it effectively disperses the shockwave throughout the solid areas of your jaw. 

You can also benefit from a custom fit if you decide to go for this product as it comes with the typical Nextfit Gel Frame boasted by the brand’s other mouthguards. Similarly to the other Venum option that we have described here, this one comes with a high-density rubber frame. 

To make sure that the Jiu-Jitsu mouthguard fits you properly, you will need to boil it for 120 seconds, let it cool off for 90 seconds, and then fit it onto your upper teeth and bite down firmly. One note we must make in regards to this item is that it is not designed for 8-year-olds or younger kids.

ProDefenda Mouth Guard

"ProDefenda" Mouthguard (Black)

This is one of the most rugged options out there as it does wonders for anyone who practices boxing, MMA, hockey, football, or baseball, but also rugby, jiu-jitsu, and a variety of other contact sports. It comes with a double-layered frame that makes it possible for you to enjoy excellent shock absorption. It also boasts a rigid outer shell, and what that means is that the mouthguard allows you to take the hardest blows without even blinking.

Similarly to other mouthguards in the same category, this particular one needs to be boiled to ensure the right fit. If you have never done that before and you’re feeling wary about the whole process, rest assured that nothing is going to go wrong as the item is accompanied by comprehensive and accurate instructions.

While some of those that have given this unit a try say that they’ve gone through some trial and error with the boiling process, most say that it is a great option for Muay Thai and BJJ. You need to make sure that the mouthguard is fully immersed in hot water; otherwise, the air holes might melt shut.

As is the case with some of the other products that we have showcased here, this one needs to be boiled and bitten on. With this one, however, you need to immerse it in hot water for just 35 seconds while with some Venum models, for example, you need to do the same for as many as 90 seconds. 

Because the manufacturer wants to make sure that you are able to use this item time and again, they’ve included a compact holder along with every purchase. The storage case makes it possible for you to keep the mouthguard protected from dirt, germs, or bacteria even as you store it in your backpack.

BJJ Mouthguard Buying Guide

Even though it’s a small piece of equipment, the mouthguard can generate a lot of confusion. What kind is the best for what you have in mind? What specific size do you need? Should you get one that’s made specifically for Brazilian Jiu-Jitsu? Find out the answers to these questions below.

Different styles of mouthguards

Not all mouthguards are created equal, especially when it comes to their design. Ready-made models are called ‘instant fit mouth guards’ because they’re ready to wear right after being taken out of their boxes. You do not need to go through overly complicated processes such as having to boil them. Their disadvantage is that they are a little bulkier than the average in this category and they can also be less secure as they do not provide a customized fit.

Oral Mart Black/Blue Youth Mouthguard for Kids - Youth Mouthguard for Karate, Flag Football, Martial Arts, Taekwondo, Boxing, Football, Rugby, BJJ, Muay Thai, Soccer, Hockey (with Free Case)

Boil-and-bite mouthguards are mouth-adapted. They are among the most popular in this line of products as they can offer you the benefit of adapting the fit at home. You first put them in some hot water so as to soften their inner layer and then you just place them over your teeth and bite down. This style is affordable and readily accessible, and best of all, it gives you the chance to tailor the product to your physical attributes.

Finally, there are also custom-fit mouthguards, and these have to be molded to your teeth by a professional. They are somewhat more expensive compared to their counterparts, and you also have to get a dental professional to fit them properly. 

Safety regulations

While there aren’t any requirements for mouthguards sold in the United States or Canada, all mouthguards sold in Europe have to be CE certified. The point here is that it’s always better to pick an item that is CE-certified as it was put through intense impact testing, and it was also tested in terms of the chemicals from its materials. Some of the compounds that should never be found in a mouthguard are BPA, formaldehyde, and Phthalates.

Comfort and fit

The ideal product should allow you to breathe, as well as speak, without any difficulty whatsoever, but it should also fit securely. To make sure that you are comfortable as you wear the mouthguard, it needs to end between your first and second molar, but still cover all of your teeth (with the exception of your back molars). If it is too large, it can cause you to gag as you’re trying to fight. 

Replacing your mouthguard

It’s always a good idea to replace your mouthguard once in a while. If you are a young BJJ fighter, you will grow, and the inside of your mouth and the shape and size of your bones will change, as well. Another situation where you need to get another mouthguard is when it no longer fits securely in your mouth. If you can just loosen it with your tongue, it’s not good for you anymore.
