Forget the two-minute timer. A new invention from Japan promises a complete dental clean in just 60 seconds, and it does all the brushing for you. The g.EN is a hand-held robotic toothbrush designed to make oral care faster and more accessible, particularly for those who find using a manual brush challenging.
How the Robotic Toothbrush Works
Developed using technology from the Waseda University Robotics Laboratory in Tokyo, the device is remarkably simple to operate. Users only need to open their mouth and hold the unit in place. Inside, 16 tiny brushes work simultaneously to clean the top and bottom teeth from all angles, completing the job in less time than it takes to eat a biscuit.
The makers, Genics, have stated that the g.EN is the result of a decade of R&D, combining robotics, ergonomics, and dentistry. Their goal was to "make tooth brushing less stressful and more reliable." The current prototype weighs 220g, supports USB-C charging, and offers several modes including 'easy', 'meticulous', 'intensive care', and a dedicated 'children' setting.
Broad Appeal and Successful Funding
The project has generated significant attention in Japan, with TV footage being viewed thousands of times. While some viewers expressed concerns about gagging, others were enthusiastic, even requesting an automated flossing attachment be developed next.
A crowdfunding campaign to bring the g.EN into mass production has already proven its market viability, smashing its initial £107,000 target. The campaign page highlights its wide target audience, from busy professionals to children, the elderly, and individuals with physical limitations who struggle with a standard brush. An optional "oral stimulation attachment" is also offered to help maintain oral function.
Performance and Accessibility Benefits
Beyond convenience, the device has serious hygiene credentials. A 2022 study indicated it could achieve an average plaque retention rate of 22.4%, a level considered to represent 'good oral hygiene' that is equivalent to or better than traditional handheld brushing.
The primary motivation, however, extends beyond mere time-saving. The inventors hope the robot brush will promote greater independence, especially for people with disabilities for whom the dexterity required for effective brushing can be a barrier. Priced at approximately £155.66 (¥32,868), it sits in a similar range to high-end, AI-powered electric toothbrushes currently on the market.
This innovation signals a shift in personal healthcare tech, moving from tools that assist us to those that can actively perform the task, potentially transforming daily routines for millions.
