Does Sugar Free Gum Help Prevent Cavities?

Many popular brands of sugar -free gum make the claim that the product prevents cavities. Is this really true?

Anahad O’Connor from the New York Times looks at these claims and concludes that “many brands contain an additive called xylitol, a natural sweetener known to fight cavity-causing bacteria. In practice, though, it’s not clear that xylitol has much impact. Some research suggests that while sugar-free gum does prevent cavities, xylitol per se is not responsible. Instead, it is the act itself of chewing gum that seems to prevent cavities.”

The bottom line is that “there is evidence that sugar-free gum reduces cavities, though that may have nothing to do with the gum’s additives.” Read more.
