How Long Will My Oral Appliance for Sleep Apnea Last?

Sleep apnea is a serious condition, and it requires ongoing management and symptom control. Therefore, once you get your custom oral appliance, it is important that you wear it consistently each night. That naturally brings up a question — how long can you expect your appliance to last?  What factors will affect its longevity, and how can you tell if it is time to get a replacement? This blog post shares some important information.

Average Life Expectancy of an Oral Appliance

With proper care, most oral appliances will last for a decent amount of time. On average, a well-maintained device lasts for 2 – 5 years. Some appliances endure even longer, depending on the quality of materials, craftsmanship, and your commitment to following the manufacturer’s care instructions. While this life expectancy is typical, it is important to remember that each appliance is unique, and your experience may vary.

Oral appliances are constructed from medical-grade materials, such as acrylic or thermoplastic, which are engineered to withstand nightly use. However, no device is indestructible. Over time, the daily pressures of use, exposure to saliva, and the process of regular cleaning can slowly break down the materials. Even small changes in the fit, such as slight warping or wear, may impact the appliance’s effectiveness. Therefore, while the average life expectancy offers a useful guideline, you should continue to evaluate your device’s condition on a regular basis.

Factors that Affect Longevity

Several factors can influence how long your device remains effective and comfortable:

• You should clean your oral appliance regularly using non-abrasive cleaners. Be sure to follow the specific instructions provided by your sleep dentist.
• It is important to rinse the device thoroughly after cleaning and always store it in a clean, dry case to prevent bacterial growth and material breakdown.
• If you grind your teeth at night (a condition known as bruxism), your oral appliance may experience increased wear and tear, which can shorten its lifespan. Your general dentist might be able to help with this problem.
• Custom-fitted, high-quality appliances generally last longer than over-the-counter alternatives due to superior materials and craftsmanship, so do not hesitate to invest in a premium device.

When to Get a Replacement

You should be vigilant for signs that your oral appliance needs to be replaced. Here are some things to look out for:

• Cracks, chips, and visible wear. Physical damage can compromise the integrity of the appliance, reducing its ability to properly position your jaw and manage your sleep apnea.
• Changes in how the device feels. If the fit becomes loose, uncomfortable, or causes irritation to your gums or teeth, this could indicate that the appliance has changed shape or that your oral anatomy has shifted. These changes may result from natural wear, dental work, or changes in your weight, all of which can affect how the device fits and functions.
• Return of your sleep apnea symptoms. This is a clear signal to seek a professional evaluation. Your dentist or sleep specialist can assess whether the device still offers effective treatment or if it is time to consider a new appliance.

You should visit your sleep dentist as often as they recommend so they can suggest adjustments to your appliance (or replacement) in a timely manner. Your diligence may help you to continue enjoying restful nights indefinitely!
