Dry Mouth at Night: Causes and Simple Fixes
Waking with a dry, sticky mouth is common and usually manageable. Saliva protects teeth and controls odor, so a dry mouth at night deserves attention.
Why it happens
Mouth breathing, certain medications, dehydration, alcohol, and aging all reduce saliva. Less saliva at night means more odor and a higher cavity risk over time.
What helps
Hydrate through the day, limit alcohol and caffeine in the evening, consider nasal breathing (mouth-taping or addressing congestion), and ask about medication side effects. A humidifier can help.
Protecting teeth when saliva is low
Because saliva normally protects teeth and balances bacteria, good hygiene matters even more. Supporting a balanced oral microbiome is part of the picture — see our review here: our ProDentim review.
When to ask a professional
Persistent dry mouth can affect teeth and may relate to medications or health conditions worth discussing with a dentist or doctor.
