Person lying awake in bed at night, a common sign of untreated sleep apnea

If you have been diagnosed with obstructive sleep apnea and cannot get along with a CPAP machine, you are in very common company. CPAP works extremely well — when it is worn. The reason dentists are involved in sleep apnea care at all is that a meaningful share of patients stop using their machine within the first year, and untreated sleep apnea is not a condition to leave alone.

At Kidder Owens Dental in Baton Rouge, Dr. Dustin Kidder, Dr. Sean Owens, and Dr. Elizabeth Kidder provide custom oral appliance therapy as an alternative for the right patients. Here is an honest comparison of the two approaches.

What Each One Does

CPAP — continuous positive airway pressure — delivers pressurized air through a mask, and that column of air holds your airway open mechanically. It addresses the obstruction directly and works across the full range of severity, including severe cases.

A custom oral appliance takes a different approach. Worn like a retainer, it holds the lower jaw slightly forward during sleep, which brings the tongue and soft tissue forward with it and enlarges the airway behind them. No mask, no hose, no power, no noise.

Both are treatments, not cures. Both work only on the nights you use them, which is the fact that ends up driving the decision more than anything else.

Where Each One Wins

CPAP is the stronger option when:

  • Your apnea is severe, or your oxygen levels drop substantially during events
  • Your apnea is central rather than obstructive — an oral appliance repositions the airway and does nothing for a signaling problem
  • You have already adapted to the machine and sleep well with it
  • Anatomy above the throat, such as significant nasal obstruction or very large tonsils, is doing most of the blocking

An oral appliance is often the better real-world option when:

  • Your apnea is mild to moderate, or you snore heavily without full-blown apnea
  • You have tried CPAP and genuinely cannot tolerate it — mask claustrophobia, pressure intolerance, skin irritation, dryness, or a partner kept awake by it
  • You travel frequently, camp, or sleep somewhere without reliable power
  • You sleep on your side or stomach and fight the mask all night
  • You would realistically wear an appliance every night and only wear the machine some nights

That last point deserves emphasis. A treatment used every night at moderate effectiveness can produce a better outcome than a more effective treatment used three nights a week. The right question is not “which is better in a study” but “which will you actually use.”

What Night-to-Night Life Looks Like

With CPAP: a mask fitted each night, a machine beside the bed, filters and tubing to clean, humidifier water to refill, and travel that means packing hardware. Modern machines are far quieter than older ones and usage data is available to you and your physician, which some patients find motivating and others find intrusive.

With an oral appliance: you put it in, you go to sleep, you take it out and brush it in the morning. It fits in a pocket. Common early side effects are extra saliva, a dry mouth, and jaw or tooth soreness in the first couple of weeks; these usually settle. Over longer periods, some patients see small bite changes, which is one of the reasons appliance therapy needs periodic dental follow-up rather than a fit-and-forget approach.

If you already have jaw joint pain or clench heavily, tell us before we design anything — an appliance that holds the jaw forward interacts with those problems, and it may need to be coordinated with TMJ therapy or ruled out.

Getting an Appliance Made

It starts with a diagnosis, not with us. Sleep apnea is diagnosed by a physician on the basis of a sleep study, either in a lab or with a home test, and that study is what establishes the type and severity. We do not diagnose sleep apnea and we do not fit appliances without a diagnosis — a device that reduces snoring while leaving apnea untreated is a genuinely dangerous outcome, because it removes the symptom that would otherwise have sent you for help.

With a diagnosis in hand, the sequence is straightforward: an exam to confirm your teeth and jaw joints can support an appliance, digital impressions or scans, a custom device made to your measurements, then a fitting appointment. From there we adjust the amount the jaw is advanced over several follow-ups, because the effective position varies from patient to patient and is dialed in rather than guessed.

Your physician may want a follow-up sleep study with the appliance in to confirm it is controlling your apnea and not just your snoring. We think that is the right call, and it is the step patients most often want to skip.

Over-the-counter “boil and bite” snoring mouthpieces are not the same thing. They are not fitted to your bite, they are not adjustable in a controlled way, and they have caused bite problems in patients who wore them for months.

Can You Use Both?

Yes, and some patients do. A common pattern is CPAP at home and an oral appliance for travel. Some patients use both together, where an appliance allows a lower, more tolerable CPAP pressure. That is a conversation between us and your sleep physician, and it is worth having rather than treating the two as a binary choice.

Why It Matters Beyond Feeling Tired

Untreated obstructive sleep apnea is associated with high blood pressure, heart disease, stroke, and type 2 diabetes, alongside the daytime consequences people notice first — fatigue, morning headaches, difficulty concentrating, irritability, and dangerous drowsiness behind the wheel.

Dentists often spot the signs before anyone else, because we see worn enamel from grinding, scalloped tongue edges, and a small airway at routine exams. If your partner has described you gasping or stopping breathing at night, that is worth mentioning at your next visit regardless of what you came in for.

Frequently Asked Questions

Will insurance cover an oral appliance? Oral appliance therapy for diagnosed obstructive sleep apnea is often processed under medical rather than dental benefits, which changes how it is submitted. We will verify your coverage before treatment starts.

How long does an appliance last? Several years with normal use and nightly cleaning. We check the fit at your regular dental visits, since a device that no longer fits properly no longer treats properly.

Can I use an appliance if I have crowns, implants, or missing teeth? Often yes, but it depends on how many teeth are available to anchor the device and how sound they are. That is exactly what the initial exam determines.

Will it stop my snoring? Frequently, yes — but reducing snoring is not proof your apnea is controlled. That is why a follow-up sleep study with the appliance in place matters.

Talk Through Your Options

If CPAP is not working for you, the answer is not to give up on treatment. Bring your sleep study results and we will tell you honestly whether an oral appliance is a reasonable fit for your case or whether you would be better served going back to your sleep physician first.
