Before you begin fitting your SISU Mouthguard, wash your hands and the guard with soap and water. Fill a glass or ceramic bowl with hot but not boiling water (SISU recommends 160 degrees) - be sure that the bowl is not made of plastic.

Place the mouth guard into the hot water until it's soft and pliable; you can use a fork to determine when it's ready. Lift the mouthguard out of the water with your fork, but be sure not to let the guard fold in on itself because the material can glue together.

Next, set the guard in your mouth and use your front teeth to bite gently on the bite pad in the middle of the guard so that you don't bite down on the perforations. You may want to use a mirror.

Hold the mouth guard in place using your teeth and tongue. Use your fingers to fold the guard straight up without stretching the material hold the guard up to the gum line on the front and sides of your teeth. Quickly close your lips over the mouthguard and breathe in deeply to create suction until the material hardens.

It's important that you leave the guard in your mouth until it's completely cool or else the mouthguard may shrink. 

Continue biting gently on the guard to keep it in place. When checking your fit, the guard should be neither too snug nor too loose. You should only be able to remove the mouth guard with your fingers. 

If you can pop it out with your tongue, the fit isn't tight enough.

Make sure the guard doesn't restrict your ability to speak. You should be able to say, "SISI mouthguard" with ease.

Finally, double check that your front teeth are lined up with the bite patch. If your fit passes all three tests and feels comfortable, then you're set. If not, you can remold your SISU mouthguard.
