Why This Topic Matters: More Than Just Thirst

Dry mouth occurs when the salivary glands do not produce enough saliva. Saliva plays a crucial role in maintaining oral health, aiding digestion, and preventing infections. It acts as a natural cleanser, washing away food particles and neutralizing acids produced by bacteria.

When saliva production decreases during sleep, symptoms such as dryness, bad breath, or a sticky feeling in the mouth may appear. Ignoring these signs can lead to long-term complications. By understanding the root causes, you can address not just the symptom, but the underlying condition affecting your health.
