Mandibular Advancement Device for Snoring: How Do They Work?

If you've tried various snoring remedies without success, you're not alone. Many people struggle to find an effective solution to this common issue.

Fortunately, there are medically backed options available. One snoring solution is the mandibular advancement device, a proven method to reduce or eliminate snoring and enhance sleep quality.

Let's explore how mandibular advancement devices work and why they might be the right choice for you.

A mandibular advancement device (MAD) — also called a mandibular advancement oral appliance, or mandibular advancement splint — is a medical-grade mouthpiece designed to prevent snoring.

It works by gently repositioning your lower jaw (mandible) forward while you sleep, helping to keep your airway open and reducing soft tissue vibration in your throat.

A mandibular advancement device is similar in appearance to a mouthguard or a retainer. It is worn over your teeth and typically consists of two trays — one for your upper teeth and one for your lower teeth. These trays are connected in a way that allows for slight adjustments in jaw positioning, depending on the model.

Snoring occurs when the muscles in your throat relax too much during sleep, partially blocking your airway and causing vibrations as air passes through. By gently moving the lower jaw forward, a MAD prevents this obstruction, making it easier to breathe freely and reducing the likelihood of snoring.

For many people, this simple yet effective adjustment can lead to quieter nights and more restful sleep.

Your airway is like a tunnel — when it's clear, air flows through easily. But when your jaw relaxes too much during sleep, the airway narrows, making breathing more difficult. 

A mandibular advancement device slightly shifts your lower jaw forward, preventing this collapse and ensuring better airflow.

Snoring occurs when airflow is partially obstructed. As air struggles to pass through, it causes soft tissues in the throat to vibrate—creating that familiar, disruptive sound. The more restricted the airway, the louder the snoring.

By holding the lower jaw in a slightly forward position, a mandibular advancement device keeps the airway open. This reduces vibrations in the soft tissue at the back of the throat and decreases snoring. For many people, this simple adjustment leads to quieter, uninterrupted sleep.

If any of the following sound familiar, this device might be worth considering:

• Chronic snoring. If snoring disrupts your sleep or your partner’s — even if you don’t have OSA — a MAD device could provide significant relief.

• Obstructive sleep apnea (OSA) . If you’ve been diagnosed with mild to moderate OSA, a MAD device could help reduce apnea episodes.

• CPAP compliance issues. If you struggle with a CPAP machine due to discomfort or inconvenience, a MAD device offers a less bulky alternative.
  
  

If you’re not sure whether you need a CPAP or a mandibular advancement device, consider speaking with a sleep specialist.

There are several types of mandibular advancement devices, each with its own advantages and drawbacks. Below is a comparison to help you decide which might be best for you.

If you’re looking for a budget-friendly option with moderate comfort, a boil-and-bite MAD is a good starting point. 

When considering a mandibular advancement device, price can vary significantly depending on the type you choose. Here’s a breakdown of what you can expect:

While cheaper options can seem tempting, they often don’t hold up well over time. Some are made from lower-quality materials that wear down quickly, requiring frequent replacements. Others can cause dental damage if they don’t fit properly.

On the other hand, a custom-fitted mandibular advancement device might seem like a larger investment upfront, but it typically lasts much longer and provides a more comfortable, effective solution.

Mandibular advancement devices offer a practical, low-maintenance solution for many people struggling with snoring and mild to moderate sleep apnea. However, they’re not without their challenges — discomfort, potential dental issues, and the need for a good fit are common concerns.

Here is a list of the pros and cons:

It’s important to weigh these pros and cons when deciding if a MAD is the right solution for you.
