About

Feno

Feno offers an AI-powered smart toothbrush that cleans your entire mouth in 20 seconds while analyzing oral health markers linked to systemic health risks. The device features built-in cameras and connects to an app providing oral health reports, brushing habit tracking, and access to oral health coaching. Products are HSA/FSA eligible.

Feno was co-founded by Dr. Kenny Brown, a Stanford-educated oral and maxillofacial surgeon, and Hamet Watt, founder of Share Ventures. The company is headquartered at 4130 Overland Avenue in Culver City, California. Feno raised $6 million in seed funding led by BOLD Capital Partners, with participation from True Ventures, Upfront Ventures, and Share Ventures. The Feno Smartbrush uses a U-shaped mouthpiece containing approximately 18,000 nylon bristles that deliver 250 strokes per tooth simultaneously. Customers use the Feno app to map their dental arch, and an algorithm selects the correct mouthpiece size from six available variations. A scanner built into the handle captures images of the gumline, tooth integrity, and signs of inflammation during each brushing session. Scans sync to the Feno app where a network of licensed dentists and a machine learning model review the data and provide personalized feedback. The company holds a 4.5 out of 5 TrustScore on Trustpilot across 70 reviews. The starter kit includes the Smartbrush handle, a mouthpiece, foaming toothpaste, and a subscription to the oral health app.

DirJournal's Perspective

Editorial analysis

Feno's 20-second cleaning cycle with embedded AI diagnostics compresses professional-grade oral assessment into a consumer device, positioning it as preventive medicine rather than hygiene tool.
