Waterpik Sonic-Fusion 2.0 Professional is the next generation of our flossing toothbrush, now new and improved with 2X the bristle tip speed vs. the original Sonic-Fusion. Now you can brush and floss at the same time! Sonic-Fusion 2.0 combines the power of an advanced sonic electric toothbrush with the proven effectiveness of the Waterpik Water Flosser. The sonic toothbrush cleans the surfaces of your teeth while the water flosser in the center of the brush head cleans deep between teeth and below the gumline to remove plaque and debris that traditional brushing and flossing can't reach. Sonic-Fusion 2.0 Professional offers 3 cleaning modes: brush, floss, or brush floss, high and low.
