Did you know Trident was the original sugarless gum? It's true. Chewing it after eating and drinking helps fight cavities, remove food particles and neutralize plaque acids. The ADA Council on Scientific Affairs' acceptance of Trident sugar-free gums is based on its finding that the physical action of chewing Trident sugar-free gums for 20 minutes after eating stimulates saliva flow, which helps to prevent cavities by reducing plaque acids and strengthening teeth.
