Dry mouth, also called xerostomia, occurs when your salivary glands don’t produce enough saliva. While often temporary, persistent dry mouth can be a warning sign of underlying health issues.
⚠️ Common Causes
- Medications – antihistamines, antidepressants, blood pressure medicines
- Dehydration – not enough fluids or excessive sweating
- Medical conditions – diabetes, Sjögren’s syndrome, HIV/AIDS
- Nerve damage – after surgery or injury
- Lifestyle factors – smoking, alcohol, caffeine
🔹 Warning Signs to Watch
Persistent dry mouth may signal something more serious if accompanied by:
- Difficulty swallowing or speaking
- Burning or sore tongue
- Mouth sores or infections (canker sores, thrush)
- Increased dental decay or gum disease
- Unexplained weight loss
- Persistent fatigue, thirst, or excessive urination (possible diabetes)
💧 Relief Tips

- Chew sugar-free gum or suck on sugar-free candies
- Avoid alcohol, caffeine, and tobacco

- Consider saliva substitutes or oral moisturizers
🩺 When to See a Doctor
