4 Ways To Check Your SISU Mouthguard Fit

So you've fitted your SISU, and you're ready to hit the field...not quite. Once you've fitted your SISU Mouthguard it's important to check to make sure that it's fitted properly. A proper fitting guard is essential for the Diffusix Technology in the mouthguard to function properly.

Unlike conventional mouthguards, the SISU mouthguard has a unique and completely different design and cannot be fitted as simply as a boil and bite. This revolutionary design is what makes SISU different and can require you to look at it with new eyes. So for first time users, there can be a little bit of a learning curve. Here's how to fit-check a SISU mouthguard in four easy steps:

  1. Tongue Check

    If your mouthguard is fitted properly you should not be able to remove it with your tongue. Since SISU is a custom fit mouthguard, it should fit snug on your teeth and snap into place like a retainer. 

    If you find that your SISU Mouthguard is too tight, put the entire guard back in the hot water and remold it using less suction. On the other hand, if your guard keeps falling out, try remolding it with more suction.

  2. Alignment

    When you fit your SISU it's crucial that your teeth are properly aligned with the bite pad of the mouthguard, where there's no perforations. Use a mirror as a guide.

  3. Covered Teeth

    After you've molded your guard, it should cover the outer surfaces of your teeth and not the roof of your mouth. SISU acts as a shield and cannot protect anything if it's on the inside of your mouth.

  4. Speech

    With a properly fitted SISU, you should be able to speak almost completely naturally. If you have too much material on the inside or roof of your mouth, it can cause a very noticeable and uncomfortable lisp.  Try to say "SISU". If it comes out with a heavy lisp, you should check your fit. 

The key to fitting SISU: when you gently bite down on the bite pad, don't let go. Keep your teeth together to prevent the guard from moving out of place during the fitting. 

Do not trim SISU, this will void the warranty. Every perforation is an important when it comes to getting the most protection.

The SISU Mouthguard uses perforations to deflect force away from your teeth and into the scientifically designed crumple zones. This is why it's super important that you aren't biting or stretching the perforations.
