Sisu Mouth Guard Review (2021): The Most Breathable Mouth Guard?

It’s the first time I’m reviewing a mouthguard and apparently, Sisu mouth guard happens to be the first mouth guard I ever used in my life. I thought for many years I didn’t need a mouthguard in BJJ.

I had a few reasons for this (two, to be exact.)

Firstly, I thought it looked stupid (arrogant I know, but I was young and dumb.) Now in my late 20s, I want to preserve my body as much as I can, including my teeth.

Secondly, I had used a mouthguard 7 years ago when I started training Muay Thai and absolutely hated it. The mouth guard restricted my breathing and gave me headaches, anxiety, and exhausted me.

The main reason I ordered a mouth guard is that the other week at the open mat, I saw a blue belt at my club have his tooth chipped from an unexpected knee to the face from a quick guard pass.

I realized that breaking your teeth just wasn’t worth it both from an aesthetic and financial perspective.

I get to keep the Hollywood smile (but seriously broken teeth are never cool) and secondly, I don’t have any dental insurance.

The cost of an implant or chipped tooth repair is not worth it at all, as from my reading it can be upwards of $5,000-8,000 for an implant.

SISU Mouth Guards Aero 1.6mm Review

Sisu Mouth Guard

I wrote this personal and honest Sisu mouth guard review for a good reason and you will realize why this mouth guard will blow away most others.

Where To Buy and How To Use SISU Mouth Guard

I did a lot of research on the internet, especially reading the BJJ Subreddit. I looked for the best lightweight Brazilian Jiu-Jitsu mouth guard and finally came upon the Sisu Aero Guard.

As an avid BJJ gear enthusiast, I made sure to read every Sisu mouth guard review I could get my hands on. And realized that this might be the perfect Jiu-Jitsu mouth guard.

I quickly looked for where to buy the Sisu mouth guard and realized there were a few places close to my house. I called and asked if they carried it, sold out, unfortunately, I guess it’s a popular item!

The next obvious step was to check on Amazon. Luckily, it was available there so I bought myself the Sisu guard, 1.6 mm version, and an antimicrobial box to put it in.

I followed the Sisu mouth guard instructions and melted the Sisu Aero Guard down with some hot water and it fits nicely on the first attempt.

Note: Make sure to suck down and use your fingers on the back teeth to really get them properly fitted.

Immediately I felt this was a completely DIFFERENT mouth guard, as it was amazingly thin. According to its website, the Sisu guard is 50% slimmer than most conventional mouth guards, for me, it seemed even less than that.

It was easy to breathe, eat, and talk. It definitely wasn’t the same clunky mouth guard I remember from Muay Thai.

Training With The Sisu Mouth Guard

The next day I went to train a No-Gi Class with my new mouth guard. I rolled a lot to really see if it affected my training and to be honest I barely felt the difference. And after a bunch of rolls, I forgot that I was even wearing it in the first place.

That’s why a good Sisu mouth guard review was necessary for me to write, to let people know you can get a mouth guard that won’t impact your training (while saving your teeth.)

I was super impressed by the Sisu mouth guard in so many different ways. From its lightweight design to its porous texture allowing saliva to drip easily, the Sisu guard fit in a nice breathable state. According to the SISU website, it is made of a special type of technology called Diffusix that scientifically distributes impact forces from a traumatic hit.

I’m yet to be hit so I can’t comment exactly on this. However, after reading SISU mouth guard reviews online, it seems to be quite protective against blows to the mouth.

Is Sisu Mouth Guard Aero 1.6mm Good for MMA?

SISU Mouth Guard Review

If you want a thicker mouthpiece for BJJ, Boxing, Muay Thai, or MMA, I’d recommended going for the SISU Mouth Guards Max 2.4mm rather than the Sisu Aero Guard.

It is 2.4 MM in thickness rather than 1.6 MM giving you a boost if you are training MMA, Muay Thai, or any other contact sport where you are getting direct blows to your teeth.

I’m yet to try SISU Mouth Guards Max 2.4mm, but I’m planning to review a few other mouth guards for you guys in the next coming months and will include this one.

Lastly, another great thing I like about these mouth guards is that Sisu offers a warranty for dental protection if Sisu fails to protect your teeth from a blow.

Of course, I’m not 100% how someone could prove this, but I’m glad the company stands by some real commitment to their product.

SISU Mouth Guard Review: Summary

Overall, I’m pretty impressed with the quality and design of Sisu mouth guards. And I hope the above review reflected that. The 1.6mm version is not perfectly suited for MMA or Boxing lovers but for beginners, it’s a great option.

It also makes it possible to talk, eat, or breath without any problem. And as I discussed, after some time, you’d even forget that there is a mouth guard applied.

If you check Amazon reviews, few buyers complaining about the mouth guard quality and how it offers little protection.

I’d partially agree with it as the Sisu Mouth Guard Aero 1.6mm isn’t meant to take harder blows. It’s more suited for beginners who want to buy the best breathable mouth guard.

For professionals, you should buy SISU Mouth Guards Max 2.4mm which provides better protection to your teeth.

Final Words

Do you think a mouthguard can save your teeth or if it’s worth getting? Or you believe in not using any and found it too embarrassed to wear (like a 20-something-year-old me?)
