How do you increase the production of saliva?

To increase saliva production, you can chew sugar-free gum or suck on sugar-free candies, as the act of chewing stimulates salivary glands. Staying hydrated by drinking plenty of water also helps maintain saliva levels. Additionally, incorporating sour foods like citrus fruits can trigger saliva production. If dry mouth persists, consulting a healthcare professional may provide further options or treatments.
