Imagine this: it’s 3 a.m., and you’re jolted awake by the sound of your own choking. Your partner tells you it happens most nights, but you don’t remember any of it. What you do remember is feeling exhausted, struggling to concentrate, and dealing with headaches that won’t go away. These are common warning signs of sleep apnea, a condition where breathing repeatedly stops and starts during sleep. Left untreated, it can affect far more than how rested you feel in the morning, since it is linked to serious cardiovascular, metabolic, and cognitive health risks. The good news is that sleep apnea is treatable, and understanding the warning signs is the first step toward getting the right care.
At Montgomery Park Dental, we see the toll that untreated sleep apnea takes on our patients’ daily lives, and we know how disruptive it can be to feel exhausted no matter how many hours you spend in bed. As a general dentistry practice in Conroe, Texas, we work alongside physicians and sleep specialists to help patients manage obstructive sleep apnea with custom oral appliance therapy, an option that many people find more comfortable and easier to stick with than a CPAP machine. Below, we walk through what sleep apnea is, why it matters, and what treatment can look like.
Understanding Sleep Apnea: Symptoms and Risk Factors
Sleep apnea is a condition marked by repeated pauses in breathing during sleep, most often because relaxed throat muscles partially or fully block the airway. The most noticeable signs are loud, chronic snoring and excessive sleepiness during the day, even after a full night in bed. Some people wake up gasping or choking, while others notice morning headaches, a dry mouth, or mood changes such as irritability. Because many of these symptoms happen during sleep, a bed partner is often the first to notice something is wrong.
Sleep apnea can affect anyone, but certain factors raise the risk, including obesity, older age, and a naturally narrow airway or enlarged tonsils. Men are diagnosed more often than women, though the risk for women increases after menopause. Family history and certain jaw or facial structures can also play a role, which is one reason a dental exam can sometimes reveal early warning signs before a person realizes they have a sleep disorder.
Health Risks of Untreated Sleep Apnea
Left untreated, sleep apnea forces the body through repeated cycles of oxygen deprivation, which puts strain on the cardiovascular system over time. This is associated with a higher risk of high blood pressure, irregular heartbeats, heart attack, heart failure, and stroke, particularly during the deeper stages of sleep when breathing interruptions tend to be longest. The effects extend beyond the heart, too. Chronic sleep fragmentation is associated with memory problems, a higher long-term risk of cognitive decline, and metabolic changes such as insulin resistance and weight gain, all of which can make the condition harder to manage over time.
How Untreated Sleep Apnea Affects Daily Life
Sleep apnea can also make everyday life noticeably harder well before any long-term risks set in. Excessive daytime sleepiness is one of the most common complaints, and it can affect concentration, reaction time, and mood. Untreated sleep apnea has been linked to a higher risk of drowsy-driving incidents, since the same fragmented sleep that leaves you tired also slows reaction time behind the wheel. Many people also describe a kind of mental fog, including trouble focusing, forgetfulness, and a higher likelihood of mood changes such as irritability, anxiety, and depression. None of this reflects a lack of willpower. It is the direct result of a body that is not getting the restorative, uninterrupted sleep it needs each night.
The Role of Weight Management in Sleep Apnea
Body weight and sleep apnea are closely connected. Extra weight around the neck and upper airway can narrow the space available for air to pass through during sleep, which makes obstructive episodes more likely, and this is why weight management is frequently discussed as part of a broader treatment plan for people who are overweight or obese. Weight loss does not resolve sleep apnea for everyone, and it should not replace medical evaluation or treatment, but for many people a modest reduction in body weight can meaningfully ease symptoms alongside other treatments such as an oral appliance or CPAP therapy. Regular exercise, limiting alcohol before bed, and a consistent sleep schedule are often recommended as complementary steps, not substitutes for a formal treatment plan.
Diagnosing Sleep Apnea: From Consultation to Sleep Testing
A physician or sleep specialist typically diagnoses obstructive sleep apnea, usually beginning with a review of your symptoms, medical history, and risk factors such as weight, age, and family history. From there, an overnight sleep study, called polysomnography, is the standard way to confirm a diagnosis and measure its severity. Some patients are also candidates for a home sleep apnea test, which uses a portable monitor to track breathing patterns and oxygen levels overnight in a more comfortable, familiar setting.
Sleep apnea severity is measured using the apnea-hypopnea index (AHI), which counts the average number of breathing interruptions per hour of sleep. Generally, an AHI of five to fifteen is considered mild, fifteen to thirty is moderate, and above thirty is considered severe. Once a diagnosis is confirmed, your physician may refer you to a dentist experienced in dental sleep medicine if oral appliance therapy is an appropriate option for your case.
Types of Oral Appliances for Sleep Apnea Treatment
Mandibular Advancement Devices and Tongue-Stabilizing Devices
According to the Cleveland Clinic, oral appliances for sleep apnea generally fall into two categories: mandibular advancement devices (MADs) and tongue-stabilizing devices (TSDs). MADs are the most commonly used option. They fit over the upper and lower teeth and gently move the lower jaw forward, which pulls the tongue forward as well and helps keep the airway open overnight. TSDs work differently. Rather than repositioning the jaw, they use a small suction bulb to hold the tongue in a forward position, which can be an alternative for people who cannot tolerate a jaw-based device. Custom-fitted appliances, made from an impression of your own teeth, tend to fit more precisely and perform better than over-the-counter or “boil and bite” versions, and because they are built by a dental professional, they can be adjusted over time as your needs change.
What to Expect at Your Fitting
If your physician has recommended oral appliance therapy, the process at a dental office generally follows a few steps.
- Initial consultation. We review your sleep study results and discuss whether an oral appliance is likely to be a good fit for your needs.
- Impressions and fitting. We take a detailed impression or digital scan of your teeth so the appliance can be custom-made to your bite.
- Delivery and adjustment. Once the appliance is ready, we fit it in the office and make adjustments for comfort and effectiveness.
- Follow-up care. Regular check-ins help confirm the appliance is working as intended and allow for further adjustments as needed.
Most people need a short adjustment period to get used to wearing an appliance overnight, and ongoing follow-up is an important part of making sure it continues to work well.
Who Can Benefit From Oral Appliance Therapy
Oral appliance therapy tends to work best for people with mild to moderate obstructive sleep apnea, or for those with more severe cases who cannot tolerate CPAP therapy. CPAP remains the standard first-line treatment recommended by most sleep specialists, but a meaningful number of patients find the mask and machine difficult to use consistently, and an oral appliance can offer a smaller, quieter, more portable alternative that can still meaningfully improve airflow during sleep. That said, oral appliances are not appropriate for everyone. They are generally not recommended for central sleep apnea, which is caused by signaling issues in the brain rather than airway obstruction, and they may not be strong enough on their own for some cases of severe OSA. Your physician and dentist can work together to help determine whether oral appliance therapy, CPAP, or a combination of treatments is the right fit for your specific situation.
The Dentist’s Role in Identifying Sleep Apnea
Many people do not realize that a routine visit for dental exams and cleanings can be an opportunity to catch early warning signs of sleep apnea. Because dentists see patients regularly and get a close look at the mouth, jaw, and airway, they are sometimes the first to notice clues such as tooth wear from grinding, a scalloped tongue, or a naturally narrow airway. While a dentist cannot diagnose sleep apnea, flagging these signs and recommending a conversation with a physician or sleep specialist is one of the ways routine dental care supports whole-body health. If you have already been diagnosed with obstructive sleep apnea and are exploring oral appliance therapy, our team can work with your physician to help determine whether a custom appliance is an appropriate option for you.

Frequently Asked Questions About Sleep Apnea Treatment
What is the difference between a CPAP machine and a custom oral appliance for sleep apnea?
A CPAP machine uses a mask connected to a pump that delivers a steady stream of pressurized air to keep your airway open all night, and it is generally considered the most effective treatment for moderate to severe obstructive sleep apnea. A custom oral appliance is a smaller, mouthguard-like device that repositions your jaw or tongue to reduce airway blockage. Oral appliances tend to be easier to travel with and get used to, but they are typically recommended for mild to moderate cases or for people who cannot tolerate CPAP therapy.
How do I know if I am a candidate for oral appliance therapy?
Candidacy for oral appliance therapy depends on factors like the severity of your sleep apnea, your jaw and tooth structure, and whether you have already tried CPAP therapy. A physician or sleep specialist typically makes this determination after reviewing your sleep study results. If oral appliance therapy looks like a good option, your provider will usually refer you to a dentist experienced in dental sleep medicine, who can evaluate your teeth and jaw to help confirm whether a custom appliance fits your situation.
Can a dentist diagnose sleep apnea?
A dentist cannot formally diagnose sleep apnea, since that requires a sleep study interpreted by a physician or sleep specialist. However, dentists often notice warning signs during routine exams, such as tooth wear from grinding, a scalloped tongue, or a narrow airway, that suggest a conversation with a physician may be worthwhile. If you are later diagnosed with obstructive sleep apnea, a dentist experienced in dental sleep medicine can work with your physician to determine whether a custom oral appliance fits your treatment plan.
How long does it take to adjust to wearing a sleep apnea oral appliance?
Most people need a short adjustment period, often a few weeks, to get used to wearing an oral appliance overnight. It is common to notice some jaw soreness, increased saliva, or minor bite changes at first, and these effects usually ease as your mouth adapts to the device. Regular follow-up appointments allow your dentist to check the fit, address any discomfort, and make adjustments so the appliance continues to work effectively and comfortably over time.
Is oral appliance therapy covered by insurance?
Coverage for oral appliance therapy varies widely between dental and medical insurance plans, and it often depends on your specific diagnosis and plan details. Some plans cover a portion of the cost when the appliance is prescribed to treat a diagnosed sleep disorder, while others do not. Our team can help you understand the paperwork involved and answer questions about your plan, though we recommend confirming details directly with your insurance provider before starting treatment.
