A slim, reassuring electric toothbrush for first-timers to deal with periodontal pockets caused by the increasingly widespread periodontal disease. The ultrafine bristles with 0.02 mm tips effectively remove buildup between teeth and gums. Sound vibration with 31,000 brushstrokes per minute at 0.4 mm wide minimizes missed areas. The cylindrical housing aims at the most compact dimensions while achieving brushing functions via innovations in the housing structure of the top cap and the positioning of the motor and switch. The simple design for better cleanliness also blends perfectly with the washroom look.
