Studies show that using xylitol as either a sugar substitute or a small dietary addition have resulted in a dramatic reduction in newly forming tooth decay, along with some reversal of existing dental caries.
Xylitol intake that consistently produces positive results ranged from 4-20 grams per day, divided into 3-7 consumption periods. Higher consumption did not result in greater reduction and may lead to diminishing results. Similarly, consumption frequency of less than 3 times per day showed no effect.
Xylitol is widely distributed throughout nature in small amounts. Some of the best sources are fruits, berries, mushrooms, lettuce, and corn cobs. One cup of raspberries contains less than one gram of xylitol. Xylitol can also be found in the form of chewing gum and lozenges
To find gum or other products containing xylitol, try visiting your local health food store or search the Internet to find products containing 100% xylitol.
