And if a few seconds were enough to brush your teeth effectively? This is the promise of Y-Brush, a new generation toothbrush developed by two Lyonnais and available since Tuesday in pre-order online. Three years of research and development were needed to turn Benjamin Cohen's ingenious idea into reality in 2015 as he watched his little cousins ​​painstakingly brushing the quenottes.

"Like all children, they had trouble to do the right thing and did not take more than a minute to brush their teeth before going to bed, "recalls the founder of

the start-up FasTeesH, installed in the incubator of the Ecam (engineering school).

The same evening, he decides to time himself and realizes that he does not hold himself the two minutes recommended by the health institutions. "The French people brush their teeth on average for 43 seconds," says the 33-year-old entrepreneur. And a quarter of them do this hygienic act only once a day.

The effectiveness of the brush on dental plaque tested for two years

His idea in mind, he s' surrounds Christophe Cadot, a 29-year-old engineer who became his partner, to develop the technology he imagines. "Our Y-Brush, which works close to an electric toothbrush, is placed on the upper and lower teeth, like a mouthguard. It is lined with fine nylon bristles, angled at 45 degrees, which allows deep cleaning everywhere, "adds Benjamin Cohen.

After five seconds of simultaneous brushing of the upper teeth completely encompbaded, the brush in Y shape, available in four sizes (for children and adults), is positioned on the lower dentition for 5 seconds again.
