Do you wake up in the morning still feeling tired? Are you drowsy, irritable or have difficulty concentrating? And is your snoring habit a running joke around your household?
If you mostly answered yes, you may have obstructive sleep apnea (OSA). This condition is more than an irritation—it could also have major health implications if not addressed.
OSA occurs when the airway becomes temporarily blocked during sleep. The tongue (or other mouth structures like tonsils or the uvula) is often the cause as it relaxes and covers the back of the throat. Although you’re asleep, the brain notices the drop in oxygen and initiates arousal to unblock the airway. As this action usually only takes a few seconds, you may not fully awake every time; but because it can occur several times a night, it can rob you of the deep sleep you need for well-being.
If you’re diagnosed with OSA, your doctor may recommend continuous positive airway pressure therapy (CPAP). This treatment uses a pump device to supply continuous pressurized air through a hose connected to a face mask worn during sleep. The elevated pressure helps keep the airway open.
While this approach is quite effective, many people find wearing the equipment uncomfortable or confining, and may choose not to use it. If that describes you, a qualified dentist may be able to provide you with an alternative called oral appliance therapy (OAT).
OAT uses a custom-made plastic oral appliance you wear while you sleep. The most common snaps over the teeth and uses a hinge mechanism to move the lower jaw (and the tongue with it) forward.
OAT is recommended for people with mild to moderate OSA, or those with severe symptoms who can’t tolerate CPAP. If you’d like to see if an OAT appliance could help you, contact us for a complete oral examination. Either treatment can improve your sleep and daily lifestyle, as well as help prevent certain health issues in the future.

You may think snoring is a minor problem, but it can be a lot more than that. Just ask hoops star Shaquille O'Neal, whose rambunctious snoring bothered his girlfriend enough for her to suspect a health problem. Her observations eventually led to Shaq's diagnosis of moderate Obstructive Sleep Apnea (OSA), which occurs when the soft tissue structures at the back of a person's throat, including the tongue, partially close off the upper airway and prevent air from moving into the lungs during sleep. Sometimes airflow can be blocked completely for 10 or more seconds.
When air flow is reduced, blood oxygen levels drop. This leads to brief waking episodes known as “micro-arousals,” which can happen sometimes more than 50 times an hour. The sleeper might not even be aware of this, even while gasping for air. Micro-arousals prevent the person from ever reaching deep, restful sleep.
Besides suffering from excessive daytime sleepiness, studies show sleep apnea patients are at higher risks of heart attacks, congestive heart failure, high blood pressure, brain damage and strokes. People with sleep apnea also have a higher incidence of work and driving-related accidents.
OSA can be treated in a few different ways. On the advice of his doctor, Shaq opted for a Continuous Positive Airway Pressure (CPAP) machine, which generates pressurized air delivered through a face mask worn while sleeping. The force of the pressurized air opens the airway (windpipe) in the same way as blowing into a balloon does.
For people with milder OSA, or who find they can't tolerate wearing a mask during sleep, an oral appliance supplied by a dental professional might be the answer. Oral appliances are worn in the mouth and are designed to gently reposition the jaw and move the tongue forward away from the back of the throat. Success rates of 80% or more have been reported using oral appliances, depending on the severity of the OSA.

Q: What is sleep apnea, and how common is it?
A: Obstructive sleep apnea is a type of sleep-related breathing disorder (SRBD) in which the airflow to the lungs is restricted — or even cut off completely — during sleep. This condition is usually caused by the collapse of soft tissues in the back of the throat, and is potentially deadly. Sleep disorders, including SRBD, are thought to affect tens of millions of people in the United States. They have been blamed for several catastrophic accidents, including the 2014 Metro-North train crash in New York, and the 1989 Exxon Valdez oil spill in Alaska.
Q: How can I tell if I might have sleep apnea?
A: Everyone has trouble sleeping sometimes. But if you constantly snore, wake up feeling irritable, and experience sleepiness and diminished performance during the day, it may mean you suffer from this condition. After a while, SRBDs can trigger depression, confusion, memory loss, and other personality changes. Medical professionals note that a person with SRBD tends to be obese; to show enlargement of the tongue, tonsils, or uvula; to have nasal polyps or congestion; and possibly, to exhibit other signs.
Q: How is sleep apnea treated?
A: There are various treatments for sleep apnea, depending on the severity of the problem and its likely cause. These include oral appliance therapy (wearing a retainer-like device in the mouth at night); orthodontic treatment and/or oral surgery; and using a CPAP (constant positive airway pressure) machine to help facilitate breathing at night. Each has advantages and disadvantages that should be discussed with a healthcare provider who has experience in the area of sleep disorders.
Q: What does all this have to do with dentistry?
A: Dentists are, of course, extremely familiar with the anatomy of the mouth. We sometimes notice signs of potential sleep problems before they become life-threatening. What’s more, we may be able to successfully treat the problem with oral appliance therapy. We can properly fabricate, fit and adjust an oral device that helps keep your airway open at night. Because it is inexpensive, removable, and relatively comfortable, an oral appliance may be a good remedy to try before moving on to more complex treatments, such as a CPAP machine or surgery. So if you think you might have SRBD, maybe it’s time to make an appointment and talk to us about it.
Sleep apnea, a form of sleep-related breathing disorders that is estimated to affect some 22 million Americans, is sometimes thought of as the “quiet culprit” lurking behind many other maladies. But ask anyone who sleeps alongside a sufferer, and you'll get a different response: It isn't quiet at all! Instead, it's often marked by loud snoring and scary episodes where breathing seems to stop. If you've ever worried that you or someone you care about may have this condition, here are five facts you should know.
1) Sleep apnea is a potentially deadly disease
For one thing, it leads to chronic fatigue that can make accidents far more likely — a special concern in potentially dangerous situations, like operating machinery or driving a vehicle. It also appears to be related to heart conditions such as high blood pressure, irregular heartbeat, coronary artery disease, and even stroke. Plus, it can lead to weight gain, depression and mood disorders.
2) People with sleep apnea may wake hundreds of times every night
These “micro-arousals” may occur 50 or more times per hour, and may keep a person from getting any relaxing sleep — even though they retain no memory of the episodes. That's why people who suffer from sleep apnea often go through their days on the verge of exhaustion. And they aren't the only ones who suffer: Their bed partners may also be kept up throughout the night, becoming anxious and irritable.
3) Persistent snoring can be a symptom of sleep apnea
Snoring is caused when breath being drawn into the lungs is obstructed by soft tissue structures in the upper airway. Most everyone snores sometimes… but chronic loud snoring is a common symptom of obstructive sleep apnea (OSA) — and the louder and more frequent the snoring, the greater the likelihood of OSA. To confirm a diagnosis of sleep apnea, a sleep study using special monitors may be conducted in a clinical setting, or an at-home test may be used.
4) Your dentist may be able to help diagnose and treat sleep apnea
What does dentistry have to do with sleep apnea? For one thing, sleep apnea is a disease that involves structures in the oral cavity — an area dentists are quite familiar with. Sometimes, fatigued folks who suffer from OSA begin snoring when they recline in the dental chair, showing their symptoms firsthand. But even if their patients don't fall asleep, dentists with proper training are recognized by the American Academy of Sleep Medicine (AASM) as being able to provide first line therapy for mild to moderate sleep disorders.
5) An oral appliance is a good step to try before more invasive treatments
If it's appropriate in your situation, your dentist can custom-fabricate an oral appliance that may alleviate sleep-related breathing disorders. This device, worn while you're sleeping, helps to maintain an open airway in the throat and to reduce breathing problems. With a success rate of around 80%, in many cases it's comparable to the more complex CPAP (continuous positive air pressure) machines, but people often find it easier to wear. Plus, it's a non-invasive treatment that can be explored before deciding on a more involved treatment, such as surgery.
