1. Wash your hands and the material with soap and water.
2. Heat water in a small bowl to approximately 170° F / 76° C (hot to the touch, but not boiling).
3. Place your SISU 3D Mouthguard into the hot water and wait until it becomes soft and pliable (use a fork or other utensil to determine mouthguard softness). It’s essential that you do not let the softened guard fold on itself. The material will glue together, making it difficult to reshape.
4. Holding the mouthguard with both hands, carefully insert the mouthguard. Make sure the back inner ridge does not fold in on itself. Bite down gently – do not make deep teeth marks.
5. Once your SISU is in the proper position, close your lips over the guard and put your tongue to the roof of your mouth. Gently create suction by swallowing until the material has hardened to a snug, perfect fit. Keep the mouthguard in your mouth for 3-5 minutes to allow the shape to set. After the guard is set, it should be snug enough that it won’t come off your teeth without using your fingers to “help” remove it.
6. If you have made a mistake don’t worry. Every SISU guard is remouldable up to 20 times. Simply place your formed SISU back in the hot water, let it soften and then start at step 3 again.
