Feno

An AI-powered smart toothbrush that brushes every tooth at once in 20 seconds

Visit feno.co

Feno is an oral health technology company reinventing the single most common health habit in the world: brushing your teeth.

The Feno Smartbrush is a U-shaped, full-mouth device that brushes every tooth simultaneously. Where a standard toothbrush has around 2,500 bristles and needs two minutes, the Smartbrush uses roughly 18,000 ultra-soft nylon bristles delivering 250 strokes to clean the front, top, back, and sides of every tooth in 20 seconds.
