Scientists don't know much about sleep even though it has been extensively studied. We do know that several hours of deep, restful sleep per night are essential for a healthy life.
Many people remain tired and unrefreshed, even after a full night's sleep. About a third of them are affected by sleep related breathing disorders (SRBD). Dentists can play a significant role in helping patients overcome these disorders, which range from frequent snoring to severe Obstructive Sleep Apnea (OSA). If you think you may have such a disorder, read on.
Under normal conditions, your upper airway is open, allowing air to flow from your nose, through your throat, and into your lungs. If you suffer from SRBD, you experience frequent reductions in the flow of air to your lungs during sleep. You may not be aware of it, but sometimes your breathing may even stop for brief periods. These reductions happen when your tongue and other soft tissues in the back of your throat collapse backwards and block 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 stages of sleep your body needs.
The resulting reduced oxygen flow to your heart and to your brain can cause serious damage. You will also be tired during the day and experience a lack of energy, even if you sleep for seven or eight hours per night. This constant drowsiness puts you at greater risk for accidents.
Because dentists generally see their patients at six-month or other regular intervals, we are in a good position to screen and refer patients with suspected SRBD to physicians for diagnosis and treatment. Dentists can also treat SRBD in a number of ways.
- One of these is Oral Appliance Therapy (OAT), in which a device that looks something like an orthodontic retainer holds your lower jaw in a forward position relative to your upper jaw, preventing your tongue and soft tissue from collapsing into your airway.
- Another consists of breathing equipment called Continuous Positive Airway Pressure (CPAP). The CPAP is a mask connected to a machine that pushes air into your lungs.
- Other treatments include oral surgery or orthodontia. The goal of these techniques is to increase the volume of air passing through your upper airway by pushing your tongue forward.
Medical insurance usually covers the cost of much of these treatments.

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.
