Ready for Better Sleep with Your Oral Appliance? Here’s What to Expect

Patient sleeping with oral appliance

Starting sleep apnea treatment with your oral appliance is exciting, and you should definitely celebrate! But once the lights go down on your first night, you might discover that your new device feels strange, possibly even uncomfortable. Don’t let the experience dampen your spirits—it’s only temporary. Here’s what to expect as you adjust to your new oral appliance, and why it’s worth it to stick with the program.

What’s Normal in the Beginning

The first week or two tends to be the hardest as you start your treatment. Most patients experience some combination of minor inconveniences, like increased saliva flow, mild jaw soreness or stiffness, temporary bite shifts, and some difficulties falling asleep.

While they can be frustrating, none of these are reasons to panic or toss your appliance in a drawer. They’ll typically ease significantly within the first few weeks as your jaw and surrounding muscles adapt.

Tips to Help You Adjust

Wearing your appliance consistently every night is the single most important thing you can do. Every night you skip out will set the adjustment process back, making the overall timeline longer.

If soreness is an issue, try some gentle jaw stretches in the morning as you wake up. If you’re not sure what to do, your dentist can show you a few good techniques. Over-the-counter pain relievers can also take the edge off in the early days if needed, but it’s best not to rely on them long-term.

Building up your routine to keep your appliance clean is especially important during the adjustment period. Lingering bacteria and plaque can give it a strange taste, create unpleasant odors, and even irritate your gums. So, rinse your appliance every morning, brush it gently, and store it in its case when you’re not wearing it.

Is It Worth It?

Adjusting to your oral appliance can be inconvenient at first, but it’s always worth it. This tiny piece of advanced dental technology will help you breathe easier during sleep. The benefits of more restorative rest will far outweigh any temporary irritation.

You’ll wake each day feeling more energized and ready to take on the day, and your body will begin to heal from any lingering stress. Just keeping the end in mind—a healthier body and mind—can make the adjustment period seem much less daunting. And, of course, if you have any issues, your dentist will always be there to help.
