About the 4.0 Clear Advanced Anti Snoring Device, Adjustable Anti Snoring Mouthpiece Mouth Guard for Men and Women, Anti Snore Solution, 1 Pack

Innovative Snoring Solution: DIFINEY Advanced 4.0 gently advances your lower jaw to help create more space through the airway, improve airflow, and reduce snoring. With a design patent application filed, its patent-pending design brings a more advanced and customizable approach to nightly snore reduction.

Targets the Mechanics Behind Snoring: Rather than simply working around the noise, DIFINEY Advanced 4.0 supports the lower jaw in a slightly more forward position while you sleep. This helps create more space behind the tongue and soft palate, reducing the soft-tissue vibration that contributes to snoring.

FDA Cleared & BPA Free: DIFINEY Advanced 4.0 is FDA cleared and made with BPA-free materials, giving you added confidence in the quality and safety of the anti-snoring device you use each night.

Fully Customizable: Custom-fit the mouthpiece to your bite at home, then fine-tune the lower-jaw advancement from 1–6 mm. Its fully adjustable design gives you greater control over fit and positioning, helping create a comfortable setup tailored to your needs and improve sleep quality for all users.
