CustomOralAppliancesCouldHelpStopSleepApnea

For millions of Americans, sleep apnea is a serious health condition. Not only can it impair your day-to-day living, you might be more susceptible to high blood pressure, heart disease or stroke.

Sleep apnea occurs when you stop breathing for short periods while asleep. When blood oxygen drops too low, your body automatically wakes you to take a breath. This can disrupt your sleep several times a night. Chronic symptoms like drowsiness, irritability or headaches during the day, or indications you're a loud snorer, are all possible signs of sleep apnea.

Fortunately, we can treat sleep apnea. One way is continuous airway pressure therapy (CPAP), a pump device that supplies pressurized air through a mask to keep the airway open during sleep. Although CPAP is effective, some people find it uncomfortable to use.

There's a more comfortable option for sleep apnea caused by mouth structures like the tongue or tonsils obstructing the airway. It involves a custom-fitted oral appliance worn while you sleep that moves these structures out of the way.

Such appliances come in two basic types. One type fits over the upper and lower teeth and uses tiny metal hinges to move the lower jaw and tongue forward away from the airway. The other fits around and presses the tongue down like a tongue depressor to move it forward.

Before starting treatment, we need to first find out if you actually have sleep apnea and what's causing it (some cases may be more acute and require advanced treatments like jaw surgery). We'll need to perform medical and oral exams and take a history, and we'll likely refer you to a sleep medicine specialist for further testing.

If you have obstructive sleep apnea, a custom-fitted appliance could be a good solution. We'll create and adjust it according to your particular mouth and jaw contours for maximum comfort. Besides the appliance, you might also lose excess weight, adjust your sleep position, seek treatment for allergies, and quit smoking. All these could help reduce sleep apnea.

In any event, your first step is to find out if you have sleep apnea. From there we'll help you find the right treatment to improve your overall health and well being.

ShaquilleONealsSlamDunkAgainstSleepApnea

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.
