Xerostomia, commonly known as dry mouth, is a medical condition that occurs due to a decrease in the production of saliva. It can have negative impacts such as difficulty in speaking, swallowing, and even an increase in dental cavities. However, there are several synonyms for xerostomia that commonly used to describe this condition. Some of them include hyposalivation, dry throat, salivary gland dysfunction, and oral dryness. It's crucial to consult a doctor if experiencing symptoms of xerostomia to manage it effectively and avoid complications. Treatment for xerostomia may include the use of over-the-counter products such as mouthwashes or prescription drugs, depending on the severity of the condition.
