Dry Mouth at Night: The Sleep Apnea Sign Most People Miss — and What It’s Costing Their Teeth

Waking up with a dry mouth once in a while usually isn’t a cause for concern. But when it becomes a nightly problem, it’s worth paying attention.

The good news is that identifying the underlying cause often leads to effective treatment—not only improving your sleep but also helping protect your teeth, gums, and overall health.
