What is Feno?
Feno Smartbrush is a health-tech device that cleans the entire mouth in a single 20-second cycle. It takes a user's mouth shape via the app's FitKit scan and produces a personalized mouthpiece, then delivers a full-mouth clean with foam cleanser. The device runs on the Feno app (iOS/Android) and is made by Feno, co-founded by Dr. Kenny Brown (oral surgeon) and Hamet Watt (entrepreneur).
