Fatigue, a “foggy” mind, and irritability are all signs you’re not getting enough sleep—and neither might your sleeping partner from your continuous snoring. You might have a common form of sleep-related breathing disorder (SRBD) known as obstructive sleep apnea.
Sleep apnea occurs when the airway becomes obstructed (usually by the tongue), resulting in a lack of oxygen. The body rouses from sleep just enough to correct the obstruction. This can occur and interrupt deep sleep several times a night, causing the aforementioned problems as well as personality changes, high blood pressure or increased stomach acid reflux. If the problem persists, sleep apnea could also become a long-term factor in the development of heart disease, diabetes or other serious conditions.
Fortunately, we can do something about it. While some may require more invasive intervention, most cases of sleep apnea can be alleviated through continuous positive airway pressure (CPAP) therapy. In this therapy, an electrical pump supplies pressurized air into a face mask worn while sleeping. The increased air pressure helps to keep the airway open.
For some patients, however, CPAP can cause discomfort like claustrophobia, nasal congestion and dryness. If that’s a concern for you, you might want to consider an oral appliance provided by your dentist.
Customized to your own individual mouth contours, this appliance is usually a two-part hinged device that draws the lower jaw and the tongue forward to open the airway. Easily adjustable, these appliances are usually more comfortable to wear than a CPAP and don’t require electricity or have the attendant noise of a CPAP pump.
They do, however, have a few drawbacks: they can disrupt saliva flow, causing either too much or too little; they may result in some morning soreness; and they can stimulate unnecessary tooth or jaw movements. For most, though, these side effects are minor compared to a better night’s sleep.
If you suspect you may have some form of SRBD, you’ll need to have it confirmed through a physical examination and possibly sleep lab testing. If it is sleep apnea, your physician and dentist can work together to help you find the right therapy to regain the benefits of a good night’s sleep.

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.
