How Long Does a Mandibular Advancement Device Take to Work?

There are several ways to treat frequent snoring. One of the most common is the Mandibular Advancement Device. These devices are worn in the mouth while sleeping and work by holding the lower jaw slightly forward. This helps keep the airway open and allows air to move more freely during the night. If you have been prescribed a mandibular advancement device, you may be wondering how long it will take before you notice a difference. Read on to learn more.

How does a mandibular advancement device work?

A mandibular advancement device fits over the upper and lower teeth, like a mouthguard. While it is being worn, the appliance gently holds the lower jaw in a forward position. This also helps move the tongue and nearby tissues away from the back of the throat. When the airway is more open, the tissues are less likely to vibrate. This reduces snoring and may also help limit breathing interruptions caused by obstructive sleep apnea.

The device must fit properly to work well. For this reason, dentists usually recommend a custom appliance instead of a store-bought option. A custom device is made to exactly match the person’s teeth and bite, which helps improve both comfort and effectiveness.

How long does it take to work?

Some people notice an improvement during the first night or within the first few days. A spouse or partner may notice that the snoring is quieter before the person wearing the device notices any change. For others, it may take several weeks to reach the best result. This is because the lower jaw is usually moved forward gradually. The dentist may begin with a mild setting and then make small adjustments over time. This gives the jaw muscles and joints time to get used to the new position.

What should you expect at first?

It is normal for a mandibular advancement device to feel unusual during the first several nights of sleep. Some people notice mild jaw stiffness, extra saliva, dry mouth, or pressure on the teeth. These symptoms often improve as the mouth adjusts. Wearing the appliance every night can help make the adjustment process easier. If discomfort continues or becomes worse, the dentist may need to change the fit or setting.

How do you know if it is working?

Reduced snoring is often the first sign. You may also sleep more peacefully and wake up feeling more rested. If the device is being used for sleep apnea, symptom improvement alone may not be enough to confirm that it is working. A follow-up sleep test may be needed to measure breathing and determine whether the appliance is controlling the condition.

What is the bottom line?

A mandibular advancement device may begin working right away, but it often takes several weeks to find the most effective and comfortable setting. The amount of time will depend on the person, the severity of the snoring or sleep apnea, and how often the device is worn. If you have questions about your appliance or are not noticing improvement, speak with your dentist. They can check the fit, adjust the devices, and help determine whether the device is working as it should.
