Dry Mouth
Frequently Asked Questions
2. What is the role of saliva?
Saliva does more than keep your mouth wet. It helps digest food,
protects teeth from decay, helps to heal sores in your mouth, and
prevents infection by controlling bacteria, viruses, and fungi in
the mouth. Saliva is also what helps us chew and swallow. Each of
these functions of saliva is hampered when a person has dry
mouth.
