Dry mouth or xerostomia refers to a condition in which the salivary glands in your mouth don't make enough saliva to keep your mouth wet. Dry mouth is often due to the side effect of certain medications or aging issues or as a result of radiation therapy for cancer.
Dry mouth can have causes that aren't due to underlying disease. Examples include not drinking enough fluids, sleeping with mouth open, dry hot weather, eating dry foods or medication side effects.
Next Steps
Frequently sipping water or other
sugar-free fluids, chewing sugar-free gum and using artificial saliva products may help to keep the mouth moist.
A room humidifier may also help.
