About Our Sleep Guardian Device

About The Silensor-sl® Anti-Snoring Device 

The Silensor-sl® anti-snoring device is a trademark of and was designed by ERKODENT®, a German dental technology company.

The device aims to put a stop to snoring while remaining comfortable and nonintrusive while you sleep. It comprises two dental splints - a blue upper and green lower - with the lower splint holding the jaw in a slightly advanced position by 2 adjustable connectors on the sides of the device. By advancing the lower jaw, the airways are kept open which reduces the vibration of tissues in the back of the mouth which causes snoring. 

Studies have shown the effectiveness of mandibular advancement splints (MAS), including the very comfortable Silensor-sl. The expansion of the pharyngeal area reduces its tendency to collapse and the apnea / hypopnea index (AHI) by up to 50%. The also slowed down airflow reduces snoring by up to 80%.

The Silensor-sl® has a long and successful track record in treating snoring, having helped over 4 million people stop snoring, and is our preferred MAD design due to comfort, wearer compliance, and the lack of metals and acrylic in the design. The product is also latex, methyl methacrylate, and BPA-free. 

The Silensor-sl® anti-snoring device and MAS treatment are the preferred choice of dental and medical practitioners, and sleep specialists in treating snoring. 

About The Sleep Guardian
