What Oral Appliances Are Recommended by Dentists for Sleep Apnea?

You wake up tired even after eight hours in bed.

So you start asking the big question:

What oral appliances are recommended by dentists for sleep apnea?

That’s what this article is about.

I’ve tested several options, talked to dentists, and sifted through the nonsense to find what actually works.

Let’s break it down.

What Is an Oral Appliance for Sleep Apnea?

Oral appliances are custom-fit devices that reposition your jaw or tongue to keep your airway open while you sleep.

They're small, quiet, and look like mouthguards.

Unlike a CPAP machine, they don’t require electricity, hoses, or a bedside commitment ceremony.

For more on the differences between CPAP and mouthguards, see our blog post: [Internal Link: CPAP vs. TMJ Appliances – What’s Right for You?]

Why Do Dentists Recommend Oral Appliances?

Here’s the kicker.

Most people with mild to moderate obstructive sleep apnea (OSA) never needed a CPAP in the first place.

Dentists recommend oral appliances because they:

• Improve airflow by moving the lower jaw forward
  
  
• Reduce snoring significantly
  
  
• Are way more comfortable than a CPAP
  
  
• Increase treatment adherence (because you’ll actually use them)
  

It’s about comfort, compliance, and keeping your throat open without bulky gear.

Mandibular Advancement Devices (MADs)

This is the most common type.

It gently pushes your lower jaw forward.

When the jaw moves, your airway opens.

Think of it like un-kinking a garden hose.

Some top MADs include:

• Reviv Mouthguard
  
  
• Herbst appliance
  
  
• TAP 3 Elite
  

I personally use Reviv. It's affordable, adjustable, and doesn’t feel like I’m sleeping with a Lego in my mouth.

Tongue Retaining Devices (TRDs)

TRDs are weird-looking but effective.

Instead of moving your jaw, they hold your tongue in place with gentle suction.

This keeps it from falling back and blocking your airway.

They're great if:

• You have jaw pain or TMJ
  
  
• You're missing teeth or wear dentures
  
  
• MADs make your bite worse
  

But yeah… expect some drooling.

Adjustable vs Fixed Oral Appliances

Fixed = pre-set position.

Adjustable = you can tweak how far forward your jaw goes.

Most people prefer adjustable.

Because guess what?

Your jaw needs time to adapt.

A good dentist will start with minimal advancement and adjust over time to avoid pain and stiffness.

Custom vs Over-the-Counter Devices

Let’s be honest.

Over-the-counter mouthguards are cheaper.

But they’re not designed to treat sleep apnea.

They’re built for teeth grinding or sports.

Dentists always recommend custom appliances because:

• They fit your bite perfectly
  
  
• They last longer
  
  
• They’re safer and more effective
  

If you're serious about results, go custom.

Is the Reviv Mouthguard Effective for Sleep Apnea?

In one word: yes.

Reviv is designed with TMJ-safe materials, is adjustable, and supports the airway by repositioning the jaw.

What I like:

• It’s less bulky than other mouthguards
  
  
• Comfortable even for side sleepers
  
  
• Doesn’t mess with my bite like cheaper options did

How Do Oral Appliances Compare to CPAP Machines?

Let’s pit them head-to-head.

CPAP:

• High compliance issues
  
  
• Bulky, noisy
  
  
• Super effective (when used)
  

Oral Appliance:

• Easier to use
  
  
• Quiet and portable
  
  
• Best for mild to moderate OSA
  

Dentists recommend oral appliances if you can’t tolerate CPAP. Which, let’s be real, is most people.

Do Oral Appliances Help With Snoring?

Absolutely.

In fact, many people without full-blown sleep apnea use them just to stop snoring.

Snoring is caused by soft tissue vibrating as airflow gets restricted.

Open the airway = no more snores.

If your partner kicks you at night, this might save your marriage.

Can You Buy an Oral Appliance Without a Dentist?

Technically yes.

But should you?

No.

Why?

Because:

• Poorly fitted devices can misalign your jaw
  
  
• You won’t get long-term support or adjustments
  
  
• You’ll probably stop using it
  

Always work with a sleep-trained dentist.

 

What If I Have TMJ Issues?

This is crucial.

If you already grind your teeth or have jaw pain, many oral appliances can make it worse.

That’s why devices like Reviv are game-changers—they’re designed to avoid joint pressure while keeping your airway open.

Side Effects of Oral Appliances

Most are minor and short-term:

• Drooling
  
  
• Jaw soreness
  
  
• Bite shifts (if improperly fitted)
  

But when fitted right?

You sleep better. Breathe better. And feel human again.

How Long Until You See Results?

For me?

Two nights in, I noticed I wasn’t waking up gasping.

Within a week, my energy improved.

Snoring dropped dramatically.

Just don’t expect miracles on night one.

How Do You Clean and Maintain Your Appliance?

Simple steps:

• Rinse after use
  
  
• Brush with a soft toothbrush (no toothpaste—it scratches!)
  
  
• Use a denture cleaner weekly
  
  
• Keep it in its case when not in use
  

That’s it.

Treat it right, and it’ll last years.

Do Insurance Plans Cover Oral Appliances?

Many do.

Especially if prescribed for sleep apnea.

You’ll usually need:

• A sleep study diagnosis
  
  
• Letter of medical necessity
  

Check your policy and ask your dentist for help with claims.

Can Kids Use Oral Appliances for Sleep Apnea?

Yes—but only with proper medical supervision.

Paediatric oral appliances must account for growth and dental development.

Never buy a DIY device for a child.

Are There Alternatives to Oral Appliances?

Yes.

• CPAP machines
  
  
• Surgery
  
  
• Positional therapy (like special pillows)
  
  
• Weight loss (can reduce symptoms)
  

But for most people who hate CPAP?

Oral appliances are the sweet spot.

 

How Do I Know If I’m a Good Candidate?

Quick checklist:

• You’ve been diagnosed with mild or moderate OSA
  
  
• You can’t tolerate CPAP
  
  
• You want a low-maintenance solution
  
  
• You’re not afraid of trying something new
  

If that’s you, talk to your dentist.
