Snoring is a common sleep problem that affects approximately 90 million Americans. While it may seem like a simple annoyance, snoring can actually have serious health consequences if left untreated. It can disrupt sleep patterns, lead to fatigue, and even increase the risk of heart disease and stroke. But have you ever wondered why some people snore while others don’t? The answer lies in the science behind snoring and the role of airway expansion mouthpieces in addressing this issue.
To understand how airway expansion mouthpieces work, we must first understand the cause of snoring. Snoring occurs when the muscles and tissues in the throat relax during sleep, causing the airway to become narrow and obstructed. As air passes through this narrowed airway, it causes the soft tissues to vibrate, resulting in the familiar snoring sound.
Airway expansion mouthpieces, also known as mandibular advancement devices (MADs), are a popular solution for snoring. These devices work by keeping the jaw in a forward position, which helps to open up the airway and prevent obstruction. But how exactly do they do this? Let’s delve into the science behind it.
The Anatomy of Snoring:
Before we can understand how MADs work, it’s important to understand the anatomy of snoring. The throat is made up of various structures, including the uvula, tonsils, soft palate, tongue, and the muscles that support these tissues. During sleep, these structures relax and can fall back, narrowing the airway.
The soft palate, which is the fleshy part at the back of the roof of the mouth, is especially prone to obstruction. This is because it is made up of muscles and tissues that are more likely to vibrate when air passes through, causing the snoring sound.
How Airway Expansion Mouthpieces Work:
Now that we have a basic understanding of the anatomy of snoring, let’s explore how airway expansion mouthpieces work to address this issue. These devices are designed to hold the lower jaw in a slightly forward position, which helps to keep the airway open and prevent obstruction.
When the lower jaw is held in a forward position, it pulls the tongue and other soft tissues forward as well, creating more space in the airway. This reduces the vibrations of the soft palate and other structures, resulting in a decrease in snoring.

The Science Behind Snoring: How Airway Expansion Mouthpieces Work
There are two main types of airway expansion mouthpieces – tongue retaining devices and mandibular advancement devices.
Tongue retaining devices work by holding the tongue in a forward position, preventing it from falling back and obstructing the airway. They are typically more suitable for people with a smaller jaw and those who have trouble keeping their mouth closed during sleep.
Mandibular advancement devices, on the other hand, work by holding the lower jaw in a slightly forward position. They are the more common type of airway expansion mouthpiece and are suitable for most people. They come in various designs, including boil and bite, adjustable, and custom-fit devices.
The Science Behind the Effectiveness of MADs:
While the concept of holding the jaw in a forward position may seem simple, the science behind the effectiveness of MADs is quite complex. Studies have shown that these devices increase the upper airway volume and improve airflow, reducing the vibrations of the soft palate and other structures that lead to snoring.
Additionally, MADs also improve the muscle tone of the airway, preventing it from collapsing during sleep. This is because holding the jaw in a forward position activates the muscles that support the upper airway, keeping it open and preventing obstruction.
Benefits of Airway Expansion Mouthpieces:
Apart from reducing snoring, airway expansion mouthpieces have other benefits as well. They can improve sleep quality, decrease daytime fatigue, and even reduce the risk of sleep apnea. By keeping the airway open, these devices also allow for better oxygen flow, which is essential for overall health and wellbeing.
In addition, MADs are a non-invasive and cost-effective solution for snoring. They are easy to use and can be custom-fit for maximum comfort. They also do not require any medication or surgery, making them a safe option for most people.
Summary:
Snoring is a common sleep problem that can have serious health consequences if left untreated. Airway expansion mouthpieces, also known as MADs, are a popular solution for this issue. They work by holding the jaw in a forward position, creating more space in the airway and reducing vibrations of the soft tissues. This results in decreased snoring and improved sleep quality. MADs also have other benefits, such as improving muscle tone and reducing the risk of sleep apnea. They are a non-invasive, cost-effective, and safe solution for snoring, making them a viable option for many people.
