If you’ve been diagnosed with sleep apnea, you’ve probably heard about CPAP machines. They’re the most common sleep apnea treatment, and for good reason. But they aren’t the only option, and they aren’t the right fit for everyone.
At MAC Dental, we get a lot of questions from patients who are trying to decide between a CPAP machine and an oral appliance. Both treatments work, but they work in very different ways. Understanding the difference can help you figure out which one fits your life best.
How Each Treatment Works
A CPAP machine uses pressurized air to keep your airway open while you sleep. You wear a mask over your nose or mouth, and the machine pushes a steady stream of air into your airways. It’s like a splint that holds everything in place. It’s incredibly effective, especially for moderate to severe sleep apnea.
An oral appliance is completely different. It looks a bit like a sports mouthguard, but it’s custom-made to fit your teeth. When you wear it, your lower jaw shifts forward just a little. That tiny movement pulls your tongue and soft tissues forward, which opens up space in your airway. It’s a simple, mechanical fix that works well for many people.
CPAP: The Powerhouse
CPAP is considered the gold standard for treating sleep apnea. It reduces the number of apnea episodes you have each night more than any other treatment.
The downside? Many patients struggle to stick with it. The mask can feel uncomfortable. Some people feel claustrophobic. Others get dry mouth or skin irritation. It also requires electricity, daily cleaning, and it’s not very portable.
Oral Appliance: The Convenient Alternative
Oral appliances are typically recommended for people with mild to moderate sleep apnea. They are also a great backup option for severe sleep apnea patients who just can’t tolerate CPAP.
The biggest advantage is comfort. There’s no mask, no noise, and no bulky equipment. They are small, portable, and require no electricity, perfect for travel. People also tend to use them more consistently because they’re easier to get used to. In fact, studies have shown patients use oral appliances for nearly two hours more per night than CPAP.
But they aren’t without trade-offs. CPAP generally does a better job of reducing the number of apnea events each hour. Some patients also experience mild jaw discomfort or temporary bite changes when they first start using an appliance.
Which One Should You Choose?
The best treatment is the one you’ll actually use every single night. A CPAP might be more powerful, but it doesn’t help if you can’t sleep with it on.
Here’s how we usually think about it at MAC Dental:
- If you have severe sleep apnea, CPAP is typically the best choice because of its clinical effectiveness.
- If you have mild to moderate sleep apnea, an oral appliance is often a great first-line treatment.
- If you travel a lot or just hate the idea of sleeping with a mask, an oral appliance might give you the freedom you need to stay consistent.
We also tell patients that these options don’t have to be either-or. Some people use a CPAP at home and an oral appliance when they’re traveling. Others combine the two to lower their CPAP pressure and make it more comfortable.
