Saliva, or spit, is made by the salivary glands and is very important for a healthy mouth. It moistens and breaks down food, washes away food particles from the teeth and gums, and helps people with swallowing. In addition, saliva contains minerals such as calcium and phosphate that help keep teeth strong and fight tooth decay.
A dry mouth, also called xerostomia, is the condition of not having enough saliva to keep the mouth wet. Dry mouth can happen to anyone occasionally-for example, when nervous or stressed. However, when a dry mouth persists, it can make chewing, swallowing, and even talking difficult. A dry mouth also increases the risk of tooth decay or fungal infections in the mouth because saliva helps keep harmful germs in check.
