"A toothbrush with AI, a camera, and a subscription.I tried out the Feno toothbrush: a full-mouth, U-shaped toothbrush. It brushes your entire mouth in 20 seconds as opposed to the typical 2-minute brush time recommended for standard toothbrushes. The Feno toothbrush seemingly did a pretty thorough job of brushing my teeth and was quick and comfortable." - Owen Grove
"The big appeal is the time saved, and having grown used to brushing my teeth for two minutes at a time, a brushing experience that ends in 20 seconds is really strange and quite delightful. The feeling of cleanliness is undeniable, Feno says that its internal pilot studies yielded 99% plaque removal in three days, while achieving that coveted 75% reduction in brushing time." - Stephen Warwick
The brush has cameras built into it that allow you to take photos and submit them in the app to get analyzed for oral health issues.
The Feno Smartbrush, in addition to being a cleaning tool, analyzes oral health markers to detect broader systemic risks. Its app allows users to track brushing habits, provides an oral health report and gives users the ability to chat with a oral health coach.
The average toothbrush has 2,500 bristles, while the Feno Smartbrush has an average of 18,000. Also, the average brush cycle takes 120 seconds while the Feno Smartbrush takes 20 because each tooth is being brushed simultaneously due to the design. - Jon Marashi, DDS

With Feno AND my teeth now. The product is AMAZING!
My teeth have never felt that “just left the dentist” feel before…unless I had just left the dentist 🤣
Brushing is so fast, it doesn’t apply the pressure I do brushing (thinking brushing harder will get a “cleaner” feel), my gums are getting proper attention (they don’t bleed & hopefully my gum recession will improve), and using the tongue scraper has become a daily routine since I now don’t brush it.
Thanks FENO!!!
