The Waterpik Sonic-Fusion Flossing Toothbrush truly cleans every angle of your teeth. By both brushing and flossing, this toothbrush ensures the tops and sides of your teeth are clean, and it also cleans between your teeth. In fact, this toothbrush flosser cleans out nearly 100% of plaque buildup in your mouth. This electric toothbrush has two buttons: one for brushing and the other for flossing. Press the brush button to use the sonic fusion brush head for the surfaces of your teeth. Then press the floss button to start up the built-in water flosser, cleaning between your teeth and your gums. Now when the dentist asks you if you floss, you can honestly answer that you do. Furthermore, this flossing brush may actually be more effective than traditional string floss, according to Waterpik. So your dentist will actually believe you—and they may even want to learn about this new bathroom gadget.
