After countless sleepless nights and frustrating attempts to solve the snoring problem with various products, we set out to find the most effective anti-snoring mouthpiece. Many products promised miracles, but only a few delivered.
We tested 24 anti-snoring mouthpieces, including models from Osmo, SnoreLessNow, SmartGuard, Mouthguardz, and Vital Sleep. We evaluated the top five based on the following criteria:
Effectiveness
The most important criterion of an anti-snoring mouthpiece is whether it actually reduces or stops snoring. We tested each model over several nights and evaluated how well it keeps the airways open to prevent disruptive snoring sounds.
Comfort
A mouthpiece can be as effective as it wants — if it's uncomfortable to wear, it won't be used for long. We examined how comfortable the mouthpieces are during sleep, whether they cause pressure points, and whether they are suitable for different jaw sizes.
How Quickly Does It Stop Snoring?
A good anti-snoring mouthpiece should deliver immediate results. We tested how quickly each model reduces snoring — whether it works from the very first night or requires an adjustment period.
Breathability
Since many people breathe through their mouth, we checked whether the mouthpieces allow free and natural breathing. Models with air channels or special openings scored higher, as they are also suitable for mouth breathers.
After 3 weeks of intensive testing, here are the Top 5 Best Anti-Snoring Mouthpieces for 2026.
