Dry Mouth (Xerostomia)
Dry mouth (xerostomia) occurs when the salivary glands do not produce enough saliva. It can lead to difficulty speaking, swallowing, and increased risk of dental problems. Common causes include dehydration, medications, and salivary gland disorders.

Seek urgent care if you experience:
- Severe difficulty swallowing or speaking.
- Swelling of face or salivary glands.
