According to the American Dental Association (ADA), chewing gum increases the flow of saliva in the mouth, which can neutralize and wash away harmful acids produced by chewing food, offering some protection to the teeth. Currently, the ADA grants a Seal of Acceptance to companies that provide proof that their gum can safely and effectively protect teeth. While chewing gum does not replace brushing and flossing, the ADA says that clinical research shows that chewing sugarless gum for 20 minutes after a meal can help prevent tooth decay.
