Understanding Dry Mouth: Causes and Treatments

Dry mouth, medically known as xerostomia, refers to a condition characterized by a lack of saliva in the mouth. Saliva plays a crucial role in maintaining oral health by moistening the mouth, aiding in digestion, and preventing infections by controlling bacteria and fungi. When the salivary glands fail to produce enough saliva, it can lead to various symptoms and complications, affecting one’s overall well-being.
