Top 10 Questions About Oral Appliance Therapy For OSA

‍

By Tiffini Stratton, DDS, D. ABDSM

You Were Told CPAP Was the Only Option. It Isn't.

You already know something is wrong with your sleep. Maybe a sleep study confirmed obstructive sleep apnea. Maybe your spouse moved to the guest room because of the snoring. Maybe you were handed a CPAP machine, tried it for a few weeks, and quietly put it in the closet because you could not stand the mask, the hose, the noise, or the feeling of air being forced into your face all night.

And now you are stuck. You are still exhausted by two in the afternoon. You still wake up with a headache and a dry mouth. You still dread going to bed because you know what the night is going to feel like. Worst of all, you may feel like you failed at treatment, when the truth is that the treatment failed you.

Here is what I want you to hear clearly: treating sleep apnea should not be harder than living with it. You deserve a therapy you can actually use every night, and for a very large number of patients, that therapy is a custom oral appliance.

I am Dr. Tiffini Stratton. I am a dentist, a Diplomate of the American Board of Dental Sleep Medicine, and the founder of Lucid Sleep Experts in San Antonio and Kerrville, Texas. My entire practice is built around one thing: helping people with sleep apnea breathe and sleep without a machine. I work side by side with a board-certified sleep physician, so you are never choosing between medical care and dental care. You get both with one coordinated team.

Every week, patients sit in my chair and ask the same ten questions about oral appliance therapy (OAT). This post answers all of them, honestly and in plain language, so you can make a confident decision about your own sleep.

1. What is oral appliance therapy, and how does it actually work?

Oral appliance therapy is a medical treatment for obstructive sleep apnea and snoring that uses a small, custom-made device worn in the mouth during sleep. The most common type is called a mandibular advancement device, which is a clinical way of saying it gently holds your lower jaw slightly forward while you sleep.

That forward position matters more than most people realize. When you fall asleep, the muscles of your throat and tongue relax. In someone with sleep apnea, that relaxation lets the tongue and soft tissue collapse backward into the airway, narrowing or completely blocking it. Your brain senses the drop in oxygen, jolts you partially awake to reopen the airway, and the cycle repeats. Some patients do this hundreds of times a night without ever remembering it.

An oral appliance interrupts that cycle at the source. By holding the jaw forward, it pulls the tongue and the tissue at the back of the throat forward with it, keeping the airway open so air moves freely. There is no pressure, no mask, and no machine. The device does its work quietly, mechanically, and all night long.

A custom appliance looks a little like a clear sports mouthguard, but it is engineered very differently. It is made from impressions or a digital scan of your teeth, fabricated in a dental laboratory, and cleared by the FDA specifically for the treatment of sleep apnea. It has an adjustment mechanism that lets me move your jaw forward in small, precise increments over several weeks until we find the position that opens your airway with the least amount of advancement.

Because the appliance fits your teeth and your bite, it should be delivered and managed by a dentist trained in dental sleep medicine, working under a sleep physician's diagnosis. That combination is what separates a medical oral appliance from something you buy online, and we will come back to that distinction in Question 4.

2. Does OAT really work, or is CPAP still the gold standard?

Oral appliance therapy works, and it is not a consolation prize. The American Academy of Dental Sleep Medicine (AADSM 2025 Standards) recommend oral appliances as a first-line option for many patients with mild to moderate obstructive sleep apnea, and for adults with sleep apnea who cannot tolerate CPAP or who prefer an alternative. This is mainstream, evidence-based medicine, not an experimental workaround.

Here is the honest comparison. In a sleep lab, CPAP usually produces a larger reduction in breathing events than an oral appliance does, especially in severe cases. If you only measure what happens during a single night with the device in place, CPAP wins on raw numbers. But that is not how treatment works in real life.

Real-world effectiveness is the strength of the therapy multiplied by how many hours you actually use it. Study after study finds that a large share of CPAP users abandon the machine or use it for only a few hours a night. A therapy that works beautifully while sitting in a closet is delivering zero benefit. Oral appliances, by contrast, are consistently used more hours per night and more nights per week, because they are simple, silent, and comfortable enough to wear until morning.

When researchers account for that difference in adherence, the health outcomes of OAT and CPAP end up remarkably similar for many patients. Blood pressure, daytime sleepiness, quality of life, and bed partner satisfaction all improve in ways that are comparable between the two therapies. The best treatment for sleep apnea is the one you will use every single night, and for many people that is an oral appliance.

None of this means CPAP is bad. For some patients with severe apnea, very low oxygen levels, or certain medical conditions, CPAP remains the right first choice, and I will tell you so. But if you have been struggling with a machine, or you were never offered anything else, you owe it to yourself to find out whether an oral appliance can deliver the same result in a form you can live with.

Ready to find out if OAT is right for you?

You do not have to keep guessing, and you do not have to keep fighting a machine. Getting started is simple:

1. Schedule a consultation at our San Antonio or Kerrville office, or by telemedicine if you prefer.
2. Get evaluated by our sleep physician and sleep dentist team. If you already have a sleep study, bring it. If you don't, we can arrange a home sleep test.
3. Start sleeping again with a custom appliance fitted, adjusted, and monitored by people who do this every day.

3. Am I a candidate for an oral appliance?

More people are candidates than have ever been told. In general, you are likely a good fit for oral appliance therapy if any of the following describes you:

• You have been diagnosed with mild or moderate obstructive sleep apnea.
• You have severe sleep apnea and have tried CPAP but cannot use it consistently.
• You snore loudly and a sleep study shows upper airway resistance or mild apnea.
• You travel often, work night shifts, or sleep in settings where a CPAP is impractical.
• You simply prefer a treatment that does not involve a mask or a machine, and your sleep physician agrees it is appropriate.

There are a few dental requirements. You need enough healthy teeth to anchor the appliance, generally a minimum of six to ten per arch, and those teeth need to be stable. Active gum disease, loose teeth, or untreated decay should be addressed first. Significant jaw joint (TMJ) problems do not automatically rule you out, but they require a careful evaluation and sometimes a different appliance design. Patients with full dentures are more limited, though some implant-supported options exist.

Two things have to happen before an appliance is made. First, a physician has to diagnose your osbtructive sleep apnea with a sleep study, either at home or in a lab. Oral appliances are medical devices prescribed for a medical condition, not dental products sold over the counter. Second, a dentist trained in dental sleep medicine has to examine your teeth, gums, jaw joints, and airway to confirm the appliance will fit well and work safely.

At Lucid Sleep Experts, both of those steps happen in the same practice. Our sleep physician handle the diagnosis and the medical management; I handle the appliance. You do not have to coordinate between two offices or carry records back and forth. If you are not a candidate, we will tell you that too, and we will help you find the treatment that is right for you.

4. How is a custom oral appliance different from a snore guard I can buy online?

This is one of the most important questions on the list, because the answer protects your teeth, your jaw, and your health.

The boil-and-bite devices sold online or at the pharmacy are marketed for snoring, not for sleep apnea. You soften them in hot water, bite down, and hope the impression holds. They are bulky, they fit loosely, and most of them lock your jaw into a single fixed position with no way to fine-tune it. Because they are not fitted to your bite by a professional, they can shift your teeth, strain your jaw joints, and irritate your gums. Worst of all, they can quiet the snoring while leaving the apnea untreated, which gives you and your bed partner a false sense that the problem is solved.

A custom medical appliance is a different category of device entirely. It is:

• Made from a precise scan or impression of your teeth, so it fits snugly, stays in place, and distributes force evenly.
• Slim and low-profile, often less than a few millimeters of material over the teeth, which makes it far easier to tolerate all night.
• Adjustable in small, controlled increments, so your jaw is advanced only as far as needed to open the airway and no further.
• FDA-cleared for the treatment of obstructive sleep apnea, not just snoring.
• Prescribed, fitted, and monitored by a dentist trained in dental sleep medicine, in partnership with your sleep physician.

The last point is the one that matters most. An oral appliance is the beginning of a treatment relationship, not a one-time purchase. Over the first several weeks, I adjust the device, check your bite and your jaw joints, and confirm with objective testing that your apnea is controlled. A guard from a website gives you none of that. If you have a diagnosis of sleep apnea, please treat it with a real medical device.

5. Is it comfortable? Will it hurt my jaw or move my teeth?

For the vast majority of patients, a custom oral appliance is comfortable within the first week or two, and far more comfortable than a CPAP mask ever was. But I would rather you hear the full picture from me than be surprised later.

During the adjustment period, it is normal to notice some mild jaw soreness in the morning, a little extra saliva or, for some people, a drier mouth, and a feeling that your teeth or bite are "different" for the first few minutes after you take the device out. These sensations are temporary. They fade as your muscles adapt to the new resting position, usually within a few weeks. I also give every patient a short set of morning jaw exercises that reset the bite and keep the joints comfortable. A couple of minutes each morning makes a real difference.

Over the long term, some patients who wear an appliance for years experience small, gradual changes in how their teeth meet. This is well documented, and it is why ongoing follow-up with your sleep dentist matters. At your regular visits I check your bite, look at your jaw joints, and compare against your baseline records. If changes are starting, we catch them early and adjust the plan. Most patients consider this a very small trade for treated sleep apnea, and many never notice a change at all.

What you should not expect is pain. If an appliance genuinely hurts, something is wrong with the fit or the advancement, and it needs to be adjusted. That is exactly why you want a dentist who does this every day rather than a mail-order device with no one to call.

The short version: the first few nights feel unfamiliar, the first few weeks feel manageable, and after that most patients forget the appliance is in. Compared with the strap marks, dry eyes, bloating, and 3 a.m. mask leaks that drive so many people away from CPAP, it is not a close contest.

6. Does insurance cover oral appliance therapy?

In most cases, yes, and it is your medical insurance that covers it, not your dental plan. That surprises a lot of patients, so it is worth explaining.

Obstructive sleep apnea is a medical diagnosis, and a custom oral appliance is a piece of durable medical equipment prescribed to treat it, the same category as a CPAP machine. Most commercial health plans, as well as Medicare, cover custom-fabricated oral appliances for sleep apnea when a few criteria are met. Those criteria typically include:

• A sleep study confirming obstructive sleep apnea
• A prescription or order from a physician
• Documentation that you have mild to moderate apnea, or that you have severe apnea and cannot tolerate CPAP
• An appliance that meets the plan's definition of a custom, adjustable, FDA-cleared device

Your out-of-pocket cost depends on your deductible, your coinsurance, and whether you have already met your deductible for the year, just as it would for any other medical service. Because dental offices are not always set up to bill medical insurance, many patients are told OAT "isn't covered" when the real problem is that the office cannot bill it correctly. If you have Medicare, we will explain in writing before treatment how your claim will be filed and what you can expect to pay.

That is not an issue at Lucid Sleep Experts. Treating sleep apnea is what we do, and our team works with medical payers every day. Before you commit to anything, we verify your benefits, explain what your plan covers, and give you a clear estimate of what you would owe. No surprises, no guesswork. If you have questions about a specific plan, ask us during your consultation and we will walk through it together.

7. What does the process look like, and how long does it take?

From your first visit to a fully adjusted appliance, most patients are sleeping better within six to ten weeks. Here is how it unfolds.

Step 1: Consultation and evaluation. We start with a conversation about your sleep, your symptoms, and anything you have already tried. If you have a sleep study, we review it. If you do not, our sleep physician orders one, usually a simple home sleep test you complete in your own bed. I then examine your teeth, gums, jaw joints, and airway to confirm you are a good candidate for an appliance.

Step 2: Records and fabrication. Once you are approved, we take a digital scan of your teeth and a bite registration that captures your jaw in the starting position. Those records go to a dental laboratory that fabricates your custom appliance. Fabrication typically takes two to three weeks.

Step 3: Delivery and fitting. When your appliance arrives, we fit it, make sure it seats comfortably on your teeth, and teach you how to insert it, remove it, clean it, and adjust it. You go home and start wearing it that night.

Step 4: Titration with remote patient monitoring. This is the part most people have never heard of, and it is where the results come from. Over the following weeks, I advance your jaw forward in small increments, usually a millimeter at a time, and we track how your breathing responds. We do not rely on guesswork or on how you feel the next morning. During titration, hen approrpiate, we enroll you in remote patient monitoring (RPM): you wear a small overnight sensor at home that records your oxygen levels, breathing patterns, and sleep quality, and our team reviews that data between visits. Each advancement is measured objectively, so we can see exactly how your airway is responding and stop at the smallest amount of advancement that fully opens it. Most patients reach that position within three adjustments over four to six weeks.

Step 5: Confirmation. When we believe we have found the right position, our sleep physician orders a follow-up sleep test with the appliance in place. That test confirms, with numbers, that your apnea is treated. From there you move into routine follow-up.

The whole process is straightforward, and you are supported at every step by the same small team.

8. How will I know it is working?

You will feel it, your bed partner will hear it, and we will measure it. All three matter.

The first signs are usually subjective and they often show up quickly. Patients tell me they wake up without the headache. They stop needing the second cup of coffee to get through the morning. They notice they are not nodding off in meetings or on the drive home. Spouses report that the snoring is gone or dramatically quieter, and that the gasping and choking sounds that used to wake them have stopped. Mood improves. Nighttime trips to the bathroom often decrease. These changes are real, and they are worth paying attention to.

But feeling better is not the same as being treated, and I never rely on symptoms alone. Sleep apnea is defined by numbers: how many times per hour your breathing stops or slows, and how far your oxygen drops when it does. The only way to know an appliance has brought those numbers into a safe range is to test with the appliance in place.

That is why a follow-up sleep study is a standard part of care at Lucid Sleep Experts, not an optional extra. After titration, our sleep physician orders a home sleep test while you wear your appliance. If the numbers show your apnea is controlled, we document it and move to maintenance. If they show residual events, we adjust further and retest. In some cases we combine the appliance with another approach, such as positional therapy, to close the gap.

Between formal tests, remote patient monitoring fills in the picture. During titration, and for a period afterward, you wear a small overnight sensor at home that tracks oxygen levels and breathing trends night by night. Our team reviews that data as it comes in, which means every appliance adjustment is measured against real numbers rather than waiting weeks between visits to find out whether it helped. It removes the guesswork, and it lets us catch a problem early instead of late.

One more thing you should expect: an annual check-in. Weight changes, new medications, aging, and dental work can all change how well an appliance performs over time. A quick yearly review keeps your treatment working the way it did on day one.

9. How long does an appliance last, and how do I take care of it?

A well-made custom oral appliance typically lasts three to five years with proper care, and some last considerably longer. Longevity depends on the material, how hard you clench or grind at night, and how consistently you clean and store the device.

Daily care is simple and takes about a minute:

• Rinse and brush it every morning with a soft toothbrush and mild soap or a cleaner made for oral appliances. Avoid regular toothpaste, which is abrasive and will scratch the surface over time.
• Let it air dry before putting it in its case. Trapped moisture encourages bacteria and odor.
• Keep it away from heat. Hot water, dishwashers, and a sunny car dashboard can warp the material and ruin the fit.
• Store it in its case, out of reach of pets. Dogs, in particular, find these devices irresistible, and we replace more appliances because of dogs than for any other single reason.
• Use a deep-cleaning tablet or soak once a week to keep the appliance fresh.

Bring your appliance to every follow-up visit. I check it for cracks, worn adjustment components, and changes in fit, and I clean and inspect it professionally. If your teeth change because of dental work, such as a new crown, a bridge, or an extraction, let us know right away. Sometimes the appliance can be relined or modified; sometimes it needs to be remade.

When the time comes to replace it, most insurance plans, including Medicare, allow for a new appliance after a set number of years or if the current one is no longer functional. We track that for you so you are never caught without treatment.

10. Can I switch from CPAP to an oral appliance, or use both?

Yes to both, and the combination is more common than most patients realize.

If you have been using CPAP and want to switch, the process is the same as for any new patient: a consultation, a review of your existing sleep study, a dental evaluation, and a conversation with our sleep physician about whether an appliance is likely to control your apnea on its own. For patients with mild to moderate disease, the answer is usually yes. For patients with severe apnea, we look at the details of your study, your oxygen levels, and your overall health before deciding. Some severe patients do very well on an appliance alone; others do best with a combined approach.

Combination therapy means using an oral appliance and CPAP together. Holding the jaw forward opens the airway enough that the CPAP can be set to a much lower pressure. Lower pressure means a smaller mask, less air leak, less dryness, and far less of the bloated, wind-tunnel feeling that makes people quit. Patients who could never tolerate full-pressure CPAP often find low-pressure CPAP with an appliance completely manageable.

Other patients keep both therapies for different situations. They wear the appliance when traveling, camping, or on nights the power goes out, and use CPAP at home. Having a backup that fits in your pocket means you are never forced to choose between an untreated night and hauling a machine through an airport.

Whatever you decide, please make the change with your care team, not on your own. Stopping CPAP without a plan means your apnea goes untreated in the gap, and that gap is where the risk lives. Tell us what is not working, and we will build a transition that keeps you protected the whole way through.

What happens if you keep waiting

I want to be direct about the stakes, because too many patients put this off for years.

Untreated sleep apnea is not just snoring and fatigue. Every time your airway collapses, your oxygen drops and your heart rate and blood pressure spike. Over months and years, that pattern raises your risk of high blood pressure, atrial fibrillation, heart attack, stroke, and type 2 diabetes. It makes weight loss harder, worsens acid reflux, and is linked to depression and memory problems. Drowsy driving caused by untreated apnea is a leading cause of serious crashes. And the cost to your relationships, your work, and your daily quality of life is enormous.

Every night you spend with a CPAP in the closet is a night your apnea goes untreated. That is the real failure, and it is entirely avoidable.

What life looks like on the other side

Now picture the alternative. You slip a small, clear appliance onto your teeth, turn off the light, and sleep. No hose. No strap marks. No hum of a machine. No mask leaking air onto your pillow at 3 a.m.

You wake up before the alarm, without a headache, and you feel rested for the first time in years. Your spouse is back in the same bed. You stop fighting to stay awake after lunch. Your blood pressure comes down. Your sleep physician sees the numbers and confirms your apnea is controlled. Bedtime becomes something you look forward to again.

That is what oral appliance therapy has done for the patients in our practice, and it is what I want for you.
