The nation's largest dentist group now says chewing gum can be good for you, as long as it's sugar-free.
The American Dental Assn. said it had awarded its seal of acceptance to Wrigley sugar-free gums Orbit, Extra and Eclipse -- based on studies funded at least partially by the maker of Wrigley gums, Chicago-based Wm. Wrigley Jr. Co.
It's the first time the ADA has allowed its seal to appear on gum, having cleared its use on thousands of products since 1930. The ADA said its independent review confirmed that those three gums help prevent cavities, reduce plaque acid and strengthen teeth.
It said studies submitted by Wrigley showed that chewing the gum products for 20 minutes after meals increases saliva production, which helps wash away plaque acid and bathes the teeth in minerals.
