Provide a powerful presentation on the importance of proper brushing and flossing that kids will love! First, rub the invisible simulated plaque over the teeth and gums. Then, after brushing the teeth, shine the included UV flashlight on the model. Any residual plaque illuminates a brilliant electric blue, making the point that casual brushing—and lack of flossing—simply won’t get the job done. A great way to promote proper oral hygiene.
