In part one of this two-part blog series, we went over some of the basics on Mandibular Advancement Devices, also known as MADs or simply mandibles. MADs are one of several devices used for the treatment of sleep apnea and certain other sleep conditions, one that limits lung obstruction by moving the jaw and tongue forward, helping stop snoring and other related issues.

At Canyon Rim Dental, we offer several sleep apnea treatments in addition to our general dentistry services. In today’s part two of our series, we’ll look further into MADs and their use for many people – things like side effects, how long they last, and some basics on fitting and regular use to keep in mind.

MAD Side Effects

There are certain minor side effects that are possible from fitted anti-snoring devices like MADs, but they are generally somewhat rare and limited. They include:

As we noted, most of these side effects reported are limited and rare. For the vast majority of patients who use them, any minor side effects are easily worth the reduction in snoring.


While the lifespan of a given MAD will depend on how often it’s used and how well it’s cared for, you can generally expect it to last for at least six months and up to two years. This will vary depending on whether the MAD is off-shelf or custom – the former tends to last closer to a year while the latter may actually last between two and three years.

Fitting, Adjusting and Comfort

The above area will also be important for fitting, with off-shelf options limited in terms of customization while custom-fit MADs contoured to your mouth specifically. Certain modern MADs will also offer basic adjustment capabilities in simple increments, or even micro-adjustments for more expensive options.

In the majority of cases, particularly those who have an MAD fitted by a dentist, use is comfortable and painless. There may be a few days or weeks of initial discomfort as you get used to the device, especially if you’ve never worn one before, but this will dissipate. If you experience significant pain beyond this point, contact your dentist.

Keeping it Clean

MADs should be cleaned after each use with basic placement in hot water, which will remove any bacteria or germs. We also recommend brushing with toothpaste or soaking in mouthwash at least a few times per week to keep the device fresh and clean.
