Stop Snoring at the Source
and Go Quiet the First Night

Snoring happens when the muscles in your throat relax during sleep, causing the airway to narrow and soft tissues to vibrate. GuardFX is a Mandibular Advancement Device (MAD) — it gently holds your lower jaw 2–7mm forward while you sleep. This small shift pulls the soft tissue taut, widens the airway, and eliminates the vibration that causes snoring. It's the exact same mechanism used in custom dental devices that cost $1,500–$3,000 at your dentist — GuardFX delivers identical results at a fraction of the price. Most customers experience a noticeable improvement from the very first night.

Absolutely. GuardFX is built with a soft medical-grade silicone interior that custom-moulds to the exact shape of your teeth, so it sits securely without digging in. Most customers feel fully comfortable by night 3 to 5 — after that, many say they forget they're wearing it. If you feel any jaw tension in the early nights, simply reduce the advancement by half a turn and build back up gradually. The adjustable design means you're never locked into a position that doesn't feel right for you.

Getting your perfect fit takes about 5 minutes. Submerge the device in hot (not boiling) water for 30 seconds until the inner material softens, then place it in your mouth and bite down firmly for 60 seconds. This creates a precise impression of your teeth that holds the device securely all night. For advancement, use the included hex key to turn the adjustment screw — clockwise to move the jaw further forward, counterclockwise to reduce. We recommend starting at 2mm and increasing by 0.5mm every 2–3 nights until snoring is fully eliminated and comfort is optimal. There are 7 settings in total, giving you full control over your results.

GuardFX is effective for the vast majority of snorers — specifically those whose snoring is caused by airway obstruction, which accounts for over 90% of all snoring cases. If you snore when lying on your back, breathe through your mouth at night, or wake up feeling unrested, it is very likely to work for you. Over 23,000 couples have already used GuardFX successfully. The adjustable system is key — because every jaw is different, being able to dial in the exact amount of advancement is what makes the difference between "it helped a bit" and "completely silent."

Yes, GuardFX is safe for nightly use. It is made from BPA-free, medical-grade thermoplastic materials, and mandibular advancement devices as a category have been clinically studied for over 30 years with an excellent safety record. They are widely recommended by dentists and sleep specialists worldwide. Some users experience mild jaw stiffness or increased salivation in the first few days — this is completely normal and resolves quickly as your jaw adapts to the new resting position. If you have severe TMJ disorder or very few remaining teeth, we recommend checking with your dentist before use.

Cleaning GuardFX is quick and simple. Every morning after removing it, rinse it under cold or lukewarm water and brush gently with a soft toothbrush — no toothpaste needed as it can be abrasive. Once a week, soak the device in a denture cleaning tablet dissolved in water for 15–20 minutes to keep it fresh and bacteria-free. Always store it in the included travel case when not in use, away from direct sunlight or heat. Never use hot water to clean it as this can warp the custom fit.

With proper daily care, GuardFX typically lasts 12–18 months before the material begins to show wear. This varies depending on factors like teeth grinding (bruxism) during sleep — if you grind heavily, you may find you go through devices faster. That's one reason many couples order the 2-pack or 3-pack: you always have a backup ready, and the per-device cost works out significantly lower. When the device begins to feel loose or the material looks worn, it's time to replace it.

All orders are processed and dispatched within 1 business day. Delivery typically takes 3–7 business days depending on your location.

We accept returns within 30 days of delivery on products that are unopened and unused, in their original sealed packaging. Because GuardFX is a personal hygiene product that is placed in the mouth, we are unable to accept returns on opened or used items — this is standard practice for all oral health devices.
