Trident Watermelon Twist Sugar Free Gum 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. Each individual pack of gum is designed so the gum stays inside, making it easy to toss in your car, backpack or desk drawer. These sticks of fruit gum are individually wrapped for freshness.
