TrueFit Mouthpiece

Using Feno is simple: just apply your preferred toothpaste, place the brush head in your mouth, and press start. The smart system automatically cleans all your teeth evenly in seconds — no complicated steps, no guesswork.

Unlike traditional brushes or gimmicky devices, Feno combines AI-powered cleaning, medical-grade bristles, and natural whitening foam for a dentist-level clean at home. It’s designed to reach every corner, protect enamel, and give you long-lasting freshness — without harsh chemicals.

Most users notice a fresher, cleaner feel after the very first use. Visible whitening typically begins within 1–2 weeks of consistent brushing, thanks to our natural xylitol + wild mint formula.

Feno comes with a wireless charging base. Simply place the device on the dock, and it begins charging automatically — no messy cables.
