Oral Health and Sleep Disorders

Many people don’t realize that oral health and sleep are closely linked. Sleep disorders can affect oral health, and oral health problems can also contribute to sleep disorders. Basically, the relationship between oral health and sleep disorders is a complex one, with both conditions affecting each other in a number of ways.

Sleep Apnea

There is evidence to suggest a potential link between oral health and sleep disorders, particularly in relation to a condition called obstructive sleep apnea (OSA) The relationship between oral health and OSA can be attributed to the role of oral structures in airway function. The oral cavity, including the tongue, soft palate, and throat, plays a crucial role in maintaining a clear and unobstructed airway during sleep.

OSA often leads to breathing interruptions during sleep, which can cause a decrease in saliva production. Reduced saliva flow results in a dry mouth (xerostomia). Saliva plays a crucial role in oral health by moistening and cleansing the mouth, neutralizing acids, and helping to prevent tooth decay and gum disease. A chronically dry mouth can increase the risk of dental problems such as tooth decay, gum inflammation, and bad breath.

Teeth Grinding

Bruxism, a sleep disorder that can often be related to sleep apnea (OSA) that causes people to clench or grind their teeth during sleep, can put stress on the teeth and jaw, which can lead to tooth wear, pain, and jaw problems.

Enlarged Tonsils & Adenoids

Enlarged tonsils or adenoids, particularly in children, can obstruct the airway during sleep and contribute to breathing difficulties and sleep disorders.
Dry mouth, a common symptom of many sleep disorders, can be caused by decreased saliva production, which can lead to tooth decay, gum disease, and other oral health problems.

Other Conditions

Gum disease can cause pain and inflammation in the gums, which can make it difficult to sleep comfortably. Tooth pain can be a major cause of sleep disturbance. Even mild tooth pain can cause people to wake up frequently during the night. Jaw problems, such as TMJ disorder, can also cause sleep disturbance. These problems can cause pain in the jaw, which can make it difficult to sleep comfortably.

If you are experiencing sleep problems, it may be helpful to mention this to your dentist to rule out any oral health conditions that may be contributing to the problem. You should also see a doctor to evaluate whether any other medical conditions that may be causing your sleep issues.
