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.

Jillian Michaels, personal trainer and star of television's The Biggest Loser isn't afraid of a tough situation — like a heart-pumping exercise routine that mixes kickboxing with a general cardio workout. But inside, she told an interviewer from Dear Doctor magazine, she's really a softie, with “a drive to be one of the good guys.” In her hit TV shows, she tries to help overweight people get back to a healthy body mass. And in doing so, she comes face-to-face with the difficult issue of sleep apnea.

“When I encounter sleep apnea it is obviously weight related. It's incredibly common and affects millions of people,” she says. Would it surprise you to know that it's a problem dentists encounter as well?

Sleep apnea is a type of sleep-related breathing disorder (SRBD) that's associated with being overweight, among other things. Chronic loud snoring is one symptom of this condition. A person with sleep apnea may wake 50 or more times per hour and have no memory of it. These awakenings last just long enough to allow an individual to breathe — but don't allow a deep and restful sleep. They may also lead to other serious problems, and even complications such as brain damage from lack of oxygen.

What's the dental connection? Sleep apnea can sometimes be effectively treated with an oral appliance that's available here at the dental office. The appliance, worn at night, repositions the jaw to reduce the possibility of the tongue obstructing the throat and closing the airway. If you are suffering from sleep apnea, an oral appliance may be recommended — it's a conservative treatment that's backed by substantial scientific evidence.

As Michaels says, “I tell people that [sleep apnea] is not a life sentence... It will get better with hard work and a clean diet.” So listen to the trainer!

Getting enough sleep is necessary for good health. We all know how energetic we feel when we are sleeping well at night. Yet, many of us do not feel rested, even after seven or eight hours of sleep. Let's answer some common questions about snoring and sleep apnea, problems that are often called sleep related breathing disorders (SRBD).

What is the purpose of sleep?
Scientists know we need sleep, at a particularly deep level, to be rested, but they are not sure why we need sleep. Sleep may have evolved as a way to conserve energy in the body, to conserve food supplies, or to reduce our risk during darkness. Sleep appears to give the brain a chance to store and organize its information and the body a chance to recuperate. Sleep studies have shown that in order to get the full benefits of sleep we need to sleep long and deeply enough to enter into a series of sleep cycles including Rapid Eye Movement (REM) and Non-Rapid Eye Movement (NREM) sleep.

What kinds of problems get in the way of the type of sleep we need?
There are eight main categories of sleep disorders, but the ones affecting the largest numbers of people are insomnia, SRBD, and Circadian Rhythm Sleep Disorders. SRBDs include snoring and Obstructive Sleep Apnea (OSA), which is a serious health problem.

How do I know if I have OSA or another SRBD?
Often, your bed-partner will tell you that you snore. Chronic loud snoring is an indicator of OSA. To make a diagnosis your physician must take a thorough sleep and medical history. The diagnosis may then be confirmed by a study in a sleep lab.

What causes sleep apnea or OSA?
Snoring and OSA happen when your tongue and other soft tissues in the back of your throat collapse backwards and block airflow through your upper airway or windpipe. You may briefly awaken as many as 50 times per night because of these breathing lapses. These brief awakenings, called micro-arousals, keep you from reaching the deep stage of sleep your body needs.

What are the treatments for sleep apnea?
Treatments include CPAP therapy, in which patients wear a mask while sleeping. The mask pushes air through the airway, keeping it open. In Oral Appliance Therapy (OAT) patients wear a device that moves the lower jaw forward, allowing more room for air to move down the airway. Oral surgical procedures and orthodontic approaches also have the goal of moving the tongue away from the throat. These are all treatments that can be carried out by a dentist who has training and experience in treatment of sleep disorders.
