When you awake in the morning do you still feel exhausted? Are you irritable during the day, unable to think or focus clearly? Is your loud snoring bothering your bed partner?
If you answered affirmatively to any of these questions, you may have sleep apnea. This happens when an obstruction (usually the tongue) blocks the airway during sleep, preventing you from breathing. Your brain notices the drop in oxygen and wakes you to re-open the airway. The arousal lasts only a few seconds, and you may not even notice. But because it can happen many times a night, these waking episodes can rob you of the deep sleep your body needs.
Sleep apnea is more serious than simply waking up grumpy. Over time, it could contribute to dangerous health conditions like high blood pressure or heart disease. If you’re noticing any of these signs, it’s important then that you undergo a complete examination by a physician or dentist trained in sleep-related issues.
Fortunately, there are ways to reduce sleep apnea. One of the most common is continuous airway pressure (CPAP): This method uses a small pump that pushes pressurized air through a face mask worn while the patient sleeps. The forced air keeps the airway open and reduces apnea episodes.
While it’s an effective method, it can be uncomfortable and cumbersome to use—some people can’t tolerate wearing the mask while they sleep. But if your sleep apnea symptoms are mild to moderate, your dentist may be able to provide an alternative therapy with a specially designed oral appliance.
Similar to a mouthguard or retainer, a sleep apnea appliance worn during sleep holds the lower jaw forward, which helps move the tongue away from the airway. It’s much less cumbersome (and noisy) than a CPAP machine. And your dentist can custom design and fabricate your appliance for a comfortable fit.
Not all cases of sleep apnea can benefit from such an appliance, or even from CPAP therapy. Extreme cases could require surgery to remove tissues blocking the airway. But most sleep apnea patients don’t require this invasive intervention. Getting checked by a qualified medical professional could open the door to a more convenient and effective way to a better night’s sleep.
We all know how much better we feel after a good night’s sleep: refreshed, energized and ready to handle — even excel at — our day-to-day responsibilities. Yet millions of people, young and old, are robbed of a good night’s rest by sleep-related breathing disorders such as sleep apnea, in which the soft tissues in the back of the throat block the airway during sleep. This temporarily disrupts airflow, causing numerous “micro-arousals” (sleep interruptions) that we may not even be aware of. A lack of sleep can make us drowsy, irritable and unfocused. In children, these typical symptoms of sleep apnea can lead to mistaken diagnoses of Attention Deficit Hyperactivity Disorder (ADHD).
The relationship between sleep apnea and behavioral problems has been highlighted in several recent scientific journal articles, including a major study published several years ago in Pediatrics, the official journal of the American Academy of Pediatrics. The lead author, Dr. Karen Bonuck, said at the time: “We found that children with sleep-disordered breathing were from 40 to 100 percent more likely to develop neurobehavioral problems by age 7, compared with children without breathing problems. The biggest increase was in hyperactivity, but we saw significant increases across [other] behavioral measures.” Therefore, an accurate diagnosis of a child’s behavioral problems — leading to the right treatment — is crucial. While sleep apnea must be diagnosed by a physician, treatment for the condition is often provided by a dentist.
What can be done for children suffering from sleep apnea? The most common treatment is surgical removal of the tonsils or adenoids. This treatment can sometimes be performed by an oral and maxillofacial surgeon, a dentist who has received several years of post-graduate surgical training. There are several other procedures oral surgeons can perform to open the airway, depending on what anatomical structures are blocking it.
Sometimes a child with sleep apnea can benefit from a procedure to expand the palate (roof of the mouth) to enlarge the airway. This is not a surgical treatment but rather an orthodontic one. An orthodontist (a dentist who specializes in moving teeth) will fit the child with a palatal expander, a butterfly-shaped device that gradually separates the two bones that form the upper jaw and roof of the mouth. This is often done to prevent crowding of teeth and other bite problems, but has been shown in some cases to improve airflow.
There is another dental approach used to treat adults and older children, whose jaw growth is complete. It’s called oral appliance therapy, and it involves wearing a custom-made device during sleep that resembles a sports mouthguard or orthodontic retainer. An oral appliance can maintain an opened, unobstructed, upper airway during sleep in various ways, including: repositioning the lower jaw, tongue, soft palate and uvula; stabilizing the lower jaw and tongue; increasing the muscle tone of the tongue.
