Sleep apnea is a potentially life-threatening sleep condition characterized by repeated interruption of breathing during sleep. The term sleep apnea is derived from the Greek etymology meaning “without breath”. Breath interruption can last anywhere from several seconds to minutes, and happen as often as 30 times or more per hour. Ongoing interrupted breathing causes an imbalance between the carbon dioxide and oxygen levels in the bloodstream, as not enough carbon dioxide is exiting and not enough oxygen is entering the body.
Sensing this imbalance, the brain sends a message to the body, telling it to wake up to restart the breathing process. People with sleep apnea will partially awake as they struggle to breathe, and this is often accompanied by loud snoring or choking sounds. Because people with sleep apnea don’t always completely awake during the episodes, they are often unaware they have a sleeping disorder and it can remain undiagnosed.
There are two main types of this disorder; central sleep apnea which occurs when the brain fails to send important signals to the breathing muscles, and obstructive sleep apnea which occurs when air cannot flow through the nose or mouth even though the body is still trying to breathe. Obstructive sleep apnea is far more prevalent and can be easily treatable by the dentist.
Common signs of obstructive sleep apnea can include severe early morning headaches, feeling tired, and sleepiness in the daytime, and insomnia. Fortunately, the dentist is equipped with the necessary technology and expertise to treat sleep apnea in several different ways.
It is very important to seek medical attention if sleep apnea is suspected. A sufferer can completely stop numerous times per hour, and this can quickly turn into a deadly situation. Obstructive sleep apnea occurs when the tissues located at the back of the patient’s throat collapses into the airway. The tongue then falls to the back of the throat, which tightens the blockage and prevents the flow of air from entering the lungs.
The problem worsens when the chest region, diaphragm, and abdomen fight for air. The efforts they make to obtain vital oxygen only cause a further tightening of the blockage. The patient must arouse from deep sleep to tense the tongue and remove the soft tissue from the airway.
Because sleep apnea causes carbon dioxide levels to skyrocket in the blood and oxygen levels to decrease, the heart has to pump harder and faster to compensate for the lack of oxygen. Sleep apnea patients can technically “die” many times each night. Sleep apnea has been linked to a series of serious heart-related conditions, and should be investigated by the dentist at the earliest opportunity.
Initially, the dentist will refer you to your primary care physician where they’ll order a sleep study in order to investigate, diagnose, and pinpoint a suitable treatment. The dentist can offer many different treatment options, which depend largely on the exact diagnosis and the health of the patient. The dentist in coordination with your physician may advise the patient to halt some habits that aggravate sleep apnea such as smoking, alcohol consumption, and tranquilizer use.
Sleeping masks were traditionally used to keep the patient’s airways open while they slept, but nowadays there are some less intrusive options. Dental devices that gently tease the lower jaw forward are very effective in preventing the tongue from blocking the main air passage. These dental devices are gentle, easy to wear, and often help patients avoid cumbersome breathing devices and may prevent unwanted surgeries to help keep the airway open.
