There are all sorts of high-quality electronic toothbrushes out there. HydraBrush aims to take some of the attention off of the Oral B Professionals and SoniCares of the world by combining 8 microbrushes that you actually bite into. By doing so, you get a full brushing on both sides of your teeth as well as a gum massage. Don’t mind the demo, as we were just as uncomfortable watching it in person as we are sure you are watching from the comfort of your screens. In any event, the HydraBrush is available for $109 USD.
