Trident Watermelon Twist Sugar Free Gum Made with Xylitol is a fruity and delicious way to freshen breath and protect your teeth. Trident sent the watermelon flavor to a yoga class and this is what happened. With 30% fewer calories than sugared gum, these sticks of watermelon gum are sweetened with xylitol, a naturally occurring sugar alcohol. The ADA Council on Scientific Affairs found that the physical of chewing Trident sugarless gum for 20 minutes after eating stimulates saliva flow which helps to prevent cavities by reducing plaque acids and strengthening teeth. These sticks of fruit gum are individually wrapped for freshness.
