A reduction in saliva leads to dry mouth, which affects the health of the teeth and the enjoyment of food. Saliva is necessary because it prevents tooth decay by limiting bacterial growth and eliminating food particles. It also improves the taste of food, makes it easier to swallow and produces enzymes that assist in digestion.
Things You'll Need
Drink water throughout the day to increase saliva.
Breathe through the nose rather than the mouth, which quickly decreases saliva output.
Chew sour or citrus-flavored gums, which boost saliva output.
Purchase non-alcoholic mouthwash, since alcohol can be drying.
Add a humidifier into the room and use at night to keep the mouth from drying out.
