How Does Sleep Apnea Impact Your Oral Health?

January 28, 2025

Sleep apnea affects millions of Americans, but many don’t realize its significant impact on oral health. This sleep disorder, characterized by breathing interruptions during sleep, creates several significant effects that can damage your teeth, gums, and overall oral wellness. So, how does sleep apnea impact your oral health? Here’s what you need to know.

How Sleep Apnea Damages Your Mouth

Sleep apnea can cause oral health problems such as:

Chronic dry mouth. When breathing stops repeatedly during sleep, your body responds by shifting to mouth breathing. Mouth breathing can dry out the oral cavity, leading to reduced saliva and an increased risk of tooth decay and gum disease.
Teeth grinding. Many sleep apnea patients unconsciously clench or grind their teeth, which can cause cracked or broken teeth, damaged fillings, and jaw discomfort [1].
Bleeding gums. Bleeding gums occur when interrupted breathing during sleep reduces oxygen flow to gum tissue, making them more susceptible to inflammation and bacterial infection [2].
TMJ pain and jaw discomfort. TMJ (temporomandibular joint) pain results from repeated clenching and strain on jaw muscles and joints during sleep apnea episodes, leading to chronic discomfort and limited jaw movement.

The Dental Professional’s Role in Sleep Apnea

Your dentist may be the first healthcare provider to spot signs of sleep apnea. During routine check-ups, they can identify telltale indicators that suggest this sleep disorder, including:

Scalloped tongue edges
Enlarged tonsils
Reddened soft palate
Worn tooth surfaces
Receding gumline

Getting Treatment for Sleep Apnea With Your Dentist

Your dentist can help protect your oral health while working alongside your sleep specialist to manage the condition. They might recommend custom-fitted oral appliances that help maintain open airways during sleep while protecting your teeth from grinding damage.

For some patients, an oral appliance offers an alternative to CPAP therapy, especially for mild to moderate cases [3]. These devices work by positioning the jaw slightly forward, helping to keep airways open during sleep.

Managing sleep apnea effectively requires a comprehensive approach that addresses both the sleep disorder and its oral health implications. Your dentist can recommend specific oral hygiene practices and products designed to combat dry mouth and protect your teeth during sleep.
