: The prototypical chinstrap for snoring is an elasticized sling that fits around the back of the upper part of the head on down and around the chin. This device is designed to keep the mouth closed during sleep with the incorrect assumption that if the mouth is closed snoring will not occur. The entire foundation of this argument is banal and scientifically inaccurate.
First let us start with the reason for snoring. When we fall asleep, it produces a loss of tone or rigidity in the soft tissues in the rear 1/3 of the roof of the mouth (toward the back of the throat). These soft tissues are called the soft palate and uvula. When an individual falls asleep, the soft tissues basically relax or lose muscle tone and collapse into the airway. This creates an obstruction to our breath-stream.

When you force a lot of air through a narrow opening, it creates considerable air pressure. This is the same concept of a pressure washing water hose. If you reduce the size of the opening in the nozzle, the water comes out under much greater pressure. Thus when you have air under pressure going past these floppy tissues, it’s like wind across a flag…it causes the tissues to flutter or vibrate. This is the reason for snoring and whether you are breathing through your mouth or your nose , the airflow (breath-stream) ends up in the same place…it enters the airway at the back of the throat and if it is under pressure, it will cause snoring.
The scientific literature is replete with studies that show that if you can pull the lower jaw (mandible) forward, you will open up the width of the airway. When the airway opens up there is less air pressure to set the soft tissues into motion (snoring). There are surgical procedures called mandibular advancement wherein the operating physician actually surgically adjusts the lower jaw forward. This is an extensive, expensive and painful process but it does work.
