Sleep apnea, a common but frequently undiagnosed condition, is more than just a sleep disorder. Its far-reaching effects touch nearly every aspect of health and well-being.
Beyond causing restless nights and chronic fatigue, sleep apnea is a significant contributor to systemic health issues such as cardiovascular disease, diabetes, and weight gain. These complications often develop silently, as the condition’s symptoms can be subtle or easily overlooked.
While much attention is given to the respiratory challenges associated with sleep apnea, its connection to dental health remains an underappreciated yet critical aspect of diagnosis and treatment.
By examining the oral health indicators and understanding the broader implications of sleep apnea, patients and healthcare providers alike can take a more comprehensive approach to managing this pervasive condition.
How Common Is Sleep Apnea, & Why Is It Often Undiagnosed?
Sleep apnea is more prevalent than many realize. For Dr. Edward H. Chappelle, Jr., DDS, one of the most pervasive issues his patients face stem from sleep apnea.
“You’d be surprised at how many people are walking around that you know have issues because of diabetes and the undiagnosed sleep apnea,” Chappelle said.
In fact, according to the American Medical Association about 30 million people in the United States have sleep apnea, but only 6 million are diagnosed. The condition often goes unrecognized because the body adapts to its symptoms, allowing individuals to function despite underlying health challenges.
One of the lesser-known impacts of sleep apnea is its role in disrupting the body’s natural repair mechanisms. During sleep, the body produces hormones such as cortisol, which are crucial for regulating stress and metabolism. However, sleep apnea can lead to an overproduction of cortisol, contributing to weight gain, cardiovascular problems, and other health issues.
Without proper rest, the body’s ability to heal and function optimally is compromised.
What’s the Link Between Sleep Apnea & Dental Health?
Sleep apnea can also significantly impact dental health. Mouth breathing during sleep often leads to dry mouth, which reduces saliva production and increases the risk of cavities, gum disease, and bad breath.
Teeth grinding, or bruxism, is another common issue associated with sleep apnea, potentially causing tooth wear, fractures, and even tooth loss. This grinding can strain the jaw, resulting in temporomandibular joint (TMJ) disorders and associated pain. Jaw misalignment and cheek biting during sleep can exacerbate discomfort, while headaches often arise from both teeth grinding and TMJ disorders.
Dentists play a key role in identifying the signs of sleep apnea. One common indicator is teeth grinding, or bruxism. “People who have sleep apnea have a tendency to grind their teeth,” Chappelle explained. “You can see signs like wear facets on teeth, which show they’ve been rubbing together.” Teeth grinding is one of the body’s reflexive responses to obstructed airways, as it helps stimulate the muscles needed to open the airway during sleep.
“It’s basically an airway issue,” Chappelle said. “The question is, what is the cause of that diminished airway? Is it that the tongue falls back? Is it that the tongue is large? Is it that you can’t breathe through your nose?”
These structural factors often start in childhood and, if untreated, persist into adulthood.
How Can Sleep Apnea Impact Overall Health?
The effects of untreated sleep apnea extend far beyond snoring and daytime fatigue. By disrupting normal sleep cycles, the condition prevents the body from achieving the deep, restorative sleep necessary for overall health.
Over time, this lack of quality sleep can lead to serious systemic issues. For instance, the overproduction of cortisol—a stress hormone linked to poor-quality sleep—hinders weight loss and promotes fat storage, often resulting in weight gain.
Cardiovascular disease is another major concern, as interrupted breathing during sleep places significant strain on the heart and blood vessels, increasing the risk of heart attack and stroke.
Additionally, poor sleep quality affects insulin sensitivity and glucose regulation, which can worsen or even contribute to the onset of diabetes.
Understanding the symptoms early can empower individuals to seek timely diagnosis and treatment, improving overall well-being.
