Understanding and Managing Dry Mouth (Xerostomia)
Why saliva matters:
Saliva protects your teeth, gums, and overall health. It helps wash away food, neutralize acids, support your oral microbiome, and keep your mouth comfortable. When saliva flow is reduced, problems like cavities, gum disease, bad breath, mouth infections, and even poor sleep can follow.
✅ Common Causes of Dry Mouth
- Medications (blood pressure, antidepressants, allergy meds, pain relievers, bladder meds, etc.)
- Mouth breathing (often linked to allergies, nasal obstruction, or sleep-disordered breathing)
- Smoking or vaping
- Alcohol or caffeine overuse
- Systemic conditions (diabetes, thyroid issues, autoimmune disease such as Sjögren’s syndrome, HIV)
- Cancer treatment (head & neck radiation, certain chemotherapies)
- Dehydration & lifestyle factors (not enough fluids, high physical activity)
- Stress & anxiety (temporary saliva reduction in “fight or flight” states)
- Age & multiple medications (common in older adults)
⚠️ Symptoms You Might Notice
- Constant dryness or sticky feeling in the mouth

- Trouble chewing, swallowing, or tasting food
- Burning sensations or sore tissues
- Bad breath
- More cavities than usual
