SISU Mouthguard FAQs

The choice between 3D, Aero, Max, Go, or Tether depends on the level of protection and the type of activity you're engaged in.

• 3D Guard is designed for an easier molding experience. It combines the ease of fitting with great protection, and the pre-formed shape allows athletes to breathe, talk, and drink easily. Suitable for various sports, the 3D guard is an excellent all-around option.
• Aero Guard is our most popular guard. Offered in 3 sizes (Small, Medium, Large), Aero is the perfect choice for any athlete. At just 1.6 mm thin, it’s ideal for those who want superior protection with a slim profile. Most commonly used in team sports such as lacrosse, field hockey, basketball, football, and hockey (with full cage helmet).
• Max Guard is 2.4 mm thin and offers more protection than the Aero. It’s ideal for sports with higher rates of direct facial contact and aggressive play. Most commonly used in rugby, MMA, and ice hockey (with visor helmet).
• GO Guard is compact and comfortable, providing crucial canine-to-canine coverage for sports where mouthguards aren’t typically required but the risk of front tooth injury exists. It’s a great choice for activities like soccer, skating or basketball.
• Tether Guard offers the same benefits as the 3D but includes a tether to secure the mouthguard to a helmet. This makes it ideal for sports like football or hockey, where attaching the guard to a helmet is preferred.

We recommend you replace your SISU Mouthguard once a season or at the very minimum once a year. Keeping it clean and letting it dry before storing will keep the germs at bay and extend the life of the guard. Your SISU Mouthguard is covered by a limited dental warranty up to $50,000 for up to 1 year after purchase.

SISU Mouthguards work great with braces because they can be remolded as teeth are shifting throughout treatment. In order to successfully fit your SISU Mouthguard, a protective barrier (such as dental wax) is needed to cover the brackets during the fitting process. We recommend having your orthodontist help with the fitting. Make sure to use a SISU Aero Medium or Large regardless of the child's ages. Do not use a SISU Aero Small with braces. Visit our braces page for more information.

The SISU Mouthgaurd (SOVA Night Guard) should not be worn as a retainer and will not keep teeth from shifting, it is best to wear the retainer provided by your orthodontist.

Your SISU Mouthguard is remoldable up to 20 times without losing its protective properties. Just put your guard in hot water (170℉) and watch it return to its original shape.

Do not trim your SISU Mouthguard. Instead, if you have a smaller mouth, size down to a SISU Aero Small mouthguard. With SISU, every part of the guard is important when it comes to getting the most protection out of your mouthguard: the perforations, the crumple zones, the boomerang shape. Not only will trimming the guard void any available dental warranty, but your teeth will be at a lot more risk for injury.

By the time you turn 11, your jaw has fully formed. You’ll need all the material provided in any of our adult mouthguards to provide you with the best protection. If you know you have a small mouth, size down to a SISU Aero Small. 

You can wear a SISU on both your top and bottom teeth, but most of our athletes prefer the comfort and strength that a single mouthguard provides. If you want protection for your lower teeth, we recommend using the Aero Guard (small) or SISU GO.

Yes, SISU is proud to offer mouthguards that are both gluten-free and free of plasticized methacrylate polymers.

Yes, the SISU mouthguard can be worn on both the top and bottom teeth for extra protection. If you want protection for your lower teeth, we recommend using the Aero Guard (small) or SISU GO.

Our mouthguards do not contain any of the following chemicals: PVC, Latex, BPA, BPS or Phthalates.

We recommend that you use our SOVA night guard for grinding and clenching. SOVA is specifically engineered to diffuse and redistribute the forces of night grinding and clenching. SOVA doesn't go as high on the gum line, has a smaller profile  and is much more comfortable than SISU for night time use. Its design is specific to night grinding and clenching.  While SISU can be used at night, under no circumstances should SOVA be used as an athletic guard.

It is a common misconception that mouth guards protect against concussions. No conclusive evidence exists that mouth guards can protect against concussions. What they can do, is protect against dental impact.

• Clean your guard using a non-whitening toothpaste or mild soap.
• You can also soak in 3% hydrogen peroxide for no more than 10 minutes
• Do not use denture tablets, dish soap, or mouthwash
• Avoid products containing alcohol or harsh cleansers
• Do not wash your SISU Mouthguard in the dishwasher or expose it to extreme heat
• Carefully rinse and dry before storing your guard at room temperature
• Consider purchasing a case to keep it safe, clean, and out of reach from your pets

FOR STORAGE IN HOT WEATHER CLIMATES

Yes, we are happy to offer the SISU Tether Mouthguard. Available now.

Yes, if your mouthguard has endured a significant impact or accident, it should be retired from any future use. Even if there are no visible signs of damage, the structural integrity of the mouthguard may be compromised, reducing its effectiveness in protecting your teeth and mouth. For optimal safety, we recommend replacing it with a new one. Other signs that a mouthguard may need to be replaced include: warping, flattening, misshapenness, holes, and other visible damage.

Please follow these steps to safely remove the guard.
Gather the following tools: A cup of very hot water, cotton swabs, cotton balls, cotton gauze, a pair of tweezers, and a washcloth.
Take care to protect the mouth to prevent burns due to hot water exposure! Use the wash cloth or cotton gauze to absorb excess hot water when applying the soaked material to the guard.
Begin by using the tweezers to apply hot water saturated cotton swabs or cotton balls to the guard area surrounding the brackets, to soften the guard.
As the guard softens, use the tweezers to slowly and gently, pull the guard away from the brackets. Focus on smaller areas, progressing until the guard can safely be removed. (Reheat the water as necessary to maintain the temperature needed to soften the guard.)
