MouthShield

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

MouthShield measures 1.5" high by 3.75" wide. That size keeps it in front of your teeth and continues to block airflow even if your mouth opens partially during sleep. If it feels too large at first, use it as-is for a week before trimming — and trim only one segment at a time, since over-trimming makes it more likely to fall out.

Yes. MouthShield is made from 100% medical-grade silicone and is free from BPA.

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

MouthShield is made from soft, 100% medical-grade silicone designed for nightly use. Most people adapt within 3–7 nights — it feels noticeably present at first, the way a retainer or night guard does, then becomes unobtrusive.

MouthShield sits in between your lips and teeth, not back near your throat, so it doesn't typically trigger a gag reflex. It does feel noticeably present for the first few nights — most people adapt within a week. If it feels too large initially, give it seven days before trimming, and trim only one segment at a time. Over-trimming makes it more likely to fall out.

MouthShield doesn't touch the skin around your mouth — it sits in between your lips and teeth. There's no adhesive, no residue, and nothing to irritate your skin. Sensitive-skin tape intolerance is a common reason people switch from mouth tape to MouthShield.

Yes. Because MouthShield is intraoral — sits between your lips and teeth — facial hair doesn't matter. There's no adhesive that needs a clean surface to stick to, and no strap that gets caught.

This is normal at first. Use it as-is for at least one week before making adjustments. If it still feels too large after that, you can trim it — but only one segment at a time. Trimming too much makes it more likely to slip out of your mouth during sleep and reduces its efficacy to create a barrier.

Learn to keep your tongue on the roof of your mouth. This is the single most important thing you can do. Use a little suction to hold it there — not too much, just enough to feel slight resistance if you try to lower your jaw. With practice, it happens automatically without even thinking about it. Be patient and keep trying, it can take up to two weeks to train your tongue to do this automatically while you sleep.

Another reason this happens is because the device has been trimmed too aggressively. We encourage you to try the MouthShield as-is for at least 1-2 weeks before trimming anything. You want it to fit snugly when your jaw is in a relaxed, slightly open sleeping position to create a full seal — but it should never be uncomfortable. Discomfort on the gumline is the main sign it may be too large.
