Why Is My Dentist Asking About My Sleep?

If your dentist has recently asked about your sleep habits, you might be wondering what your oral health has to do with your sleep. As it turns out, dentists can play an important role in identifying potential sleep disorders, such as sleep apnea.

Sleep apnea is a serious condition where your breathing repeatedly stops and starts during sleep, often due to a blocked airway. Dentists are uniquely positioned to spot signs of sleep apnea, as they regularly examine your mouth, throat, and jaw—key areas involved in breathing during sleep.

Here are a few reasons your dentist might be asking about your sleep:

1. Signs of Grinding and Jaw Issues Many people with sleep apnea grind their teeth (bruxism) during sleep or have jaw pain from clenching. Dentists can often spot signs of wear on the teeth, which may indicate that you’re struggling to breathe during the night.

2. Oral Anatomy Clues Dentists are trained to notice physical features like a small jaw, a large tongue, or a narrow airway—anatomical traits that may contribute to sleep apnea.

3. Collaboration in Treatment In some cases, dentists can help treat sleep apnea with Oral Appliance Therapy (OAT). These devices are custom-made to keep the airway open while you sleep, offering an alternative to the traditional CPAP machine.

So, the next time your dentist asks how well you’re sleeping, it’s not just a casual question—it could be a clue to a better night’s rest and improved overall health.
