This is not your father's toothbrush: the HydraBrush Express toothbrush has more than one head. No more up and down for you — the multiheaded power brush brushes the outside, inside, and bite surface of your teeth all at the same time. Simply bite down between the opposing heads and guide the HydraBrush around your tooth arch. The heads move back and forth cleaning and scrubbing the plaque off the tooth surfaces while cleaning the dreaded gum line. — Ken Sander
