MouthShield comes with a 60-day money-back guarantee, try it risk-free. We encourage you to try and use it for at least 14 days since most people need a week or two to fully adapt. If it's not working for you after that, reach out to start a return and you'll receive a full refund - minus any discounts and the initial $5 shipping charge occurred on our end if you select standard shipping.

Both the MouthShield and its packaging are manufactured in Minnesota, USA.

This is normal — and actually a good sign. If you've been a mouth breather, your body has likely been overproducing saliva for a long time to compensate for the dryness mouth breathing causes. Now that MouthShield is keeping your mouth closed, your body hasn't caught up and is still producing that same excess saliva. It takes a little time for production to recalibrate to the new, healthier environment.

The MouthShield is designed and sized to be used safely as directed. At 1.5" high by 3.75" wide, the device is intended to rest comfortably between the teeth and lips during sleep. When used as directed by adults, the product's dimensions make inadvertent ingestion highly unlikely. As with any oral device, MouthShield should be used only as directed and kept out of reach of children. If you have specific health concerns, we recommend consulting with a qualified healthcare provider.

100% medical-grade silicone — soft, flexible, hypoallergenic, and BPA-free. The same material grade used in many implantable medical devices.

If your therapy is working well and you don't have mouth leaks, you probably don't need it. MouthShield is most useful for nasal CPAP users who lose pressure through their mouth, get dry mouth, or have been told they need to switch to a full-face mask because of mouth breathing. In those cases, it's a low-cost, reversible addition to try before changing your mask setup.
