Xylitol

Use xylitol in gum or mint form, especially immediately after meals. Start slowly with one or two after a meal rather than using large amounts all day. Xylitol is preferentially consumed by Streptococcus mutans, which cannot produce acid from it; it may inhibit or kill S. mutans, reduce gum inflammation, and increase saliva production, particularly when used after an early-day or noon meal.
