Dry mouth—known medically as xerostomia—is a condition that occurs when saliva glands in the mouth don’t work properly, causing a parched feeling in the mouth. Other symptoms include a rough tongue, mouth sores, and cracked lips.
Saliva is a necessary part of the digestion process, as well as a major defense mechanism that your body needs to maintain good dental health. Saliva protects the mouth against gum disease and tooth decay. While not a serious medical condition, dry mouth can be a sign of a larger medical problem.
