4. Oral health issues
Gingivitis, cavities, and gum disease create bacterial buildup, which can worsen dryness and discomfort. Regular brushing, flossing, and dental visits go a long way in keeping the mouth healthy and moist.
5. Underlying conditions
Some medical conditions — such as diabetes, bile reflux, hyperthyroidism, or even fever — can increase fluid loss, disrupt digestion, or speed up metabolism. Each of these places extra demand on the body and may trigger persistent dry mouth.
When to Take It Seriously
Occasional dryness isn’t unusual. But if it happens regularly, it’s worth paying closer attention. Start with simple steps: stay hydrated, avoid heavy meals late at night, and maintain strong oral hygiene.
If the problem continues despite lifestyle adjustments, consult a doctor. What feels like a minor irritation could be the body’s way of asking for care — and tending to it early can improve both sleep quality and overall health.
