Too Lazy to Brush? A Tiny Oral-care Robot Could do it for you - Scitke

A newly developed oral-hygiene robot could make a big difference for people who find brushing tedious or struggle with it due to motor impairments. Created by researchers at Japan’s Waseda University and named g.eN, the device can clean your teeth in just one minute — all you have to do is hold it close to your mouth. — Image Credits: Divulgação/Genics

A new oral-hygiene robot from Waseda University, called g.eN, could help people who find brushing difficult. It cleans teeth in one minute—just hold it near your mouth.

How the Robotic Toothbrush Works

The robotic toothbrush uses 14 tiny brush heads to clean the mouth, moving up, down, left, and right at the press of a button. A small motor built into the device powers these movements.

Gen Eida, director of Genics, explains that in the future the device could work alongside dental clinics and use data such as dental arch details and eating habits to deliver customized brushing settings through smartphone integration.

Researchers say the device, which includes operating modes like “Easy,” “Careful,” “Special Care,” and “Child,” is set to be introduced as the world’s first oral-hygiene robot. The current model weighs 220 grams and charges via USB-C.

Proven Effectiveness in Plaque Removal

A study presented at the 2022 Japanese Society of Dental Health conference found that the brush achieved an average plaque retention rate of 22.4%, indicating cleaning performance equal to or better than traditional brushing while meeting accepted oral hygiene standards.

Currently, retailers sell the g.eN in Japan for 36,520 yen (about 1,261 Brazilian reais), though only limited units are available. The developers have launched a fundraising campaign to support larger-scale production for wider commercial release.
