Brush to reduce major disease risks

Featured In

"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

How many of us really put in the 2-plus minutes of brushing that dentists recommend? And are we really putting brush to tooth as effectively as we should? Feno cuts the time to just 20 seconds, and its Smartbrush does the work for you. - Carly Quellman

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.

Wired Logo

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

    It's like getting a dental cleaning! Everyday!

    I love my Feno! My dental hygienist said I left her with. Nothing to clean! She did. A little scraping here and there but said overall my teeth looked fabulous! So did the dentist! They said keep on doing whatever you're doing . I told them I was using the Feno. They said well it's doing a great job. I think Feno may take over dental cleanings someday!

    It's wonderful that both your hygienist and dentist noticed the difference and encouraged you to keep doing whatever you're doing. When dental professionals recognize the quality of clean you're achieving at home, it shows that our innovative approach is truly delivering on its promise. We're particularly excited that you told them about Feno - having that professional validation means the world to us!

    Love my Feno

    Product and foam toothpaste is great! I get 20 seconds on each and every tooth while brushing, that’s equivalent to brushing for like 10 minutes with a conventional brush!

The Fastest, Most Comprehensive Clean: Truefit Mouthpiece for a 20s full mouth brush

Our Mission

After seeing the direct link between oral health and diseases like cancer and heart disease, I couldn’t stand by while otherwise healthy people developed life-threatening conditions in part because of their poor oral health. Our mission at Feno is born from that simple truth: Caring for your teeth can help each of us live better and longer. We’re out to advance oral care as the gateway to whole body health and to equip every home with transformative oral health technology.

FAQ

How often do I need to replace the Mouthpiece?

For the best brushing experience, we recommend replacing your TrueFit Mouthpiece every 3 months. You can easily order refills on our website. Locate the Shop All Page and there you go!

How is the Feno Smartbrush™ different from other electric toothbrushes?

The Feno Smartbrush is a radical step forward for oral health. The average toothbrush has 2,500 bristles; the Feno Smartbrush has an average of 18,000. The average toothbrush brushes each tooth one at a time; the Feno Smartbrush brushes all teeth simultaneously. The average brush cycle takes 120 seconds; the Feno Smartbrush takes 20.

The Feno Smartbrush is also the first brush that takes deep scans of your teeth and gums to provide ongoing insights into the condition of your oral health. An astonishing 90% of individuals suffer from some form of gum disease, an oversight we aim to correct with the Feno Smartbrush, designed as the product to bridge oral health and overall health.

Can my kids use my Feno Smartbrush?

We’ve heard that parents are hungry for a child-sized version of our Smartbrush, and we are working on one, but right now, our Mouthpieces are made only for adults. Please don’t share your Feno Smartbrush with your kids.

How do I know the mouthpiece size that is right for me?

We will send you an email with instructions on how to determine your mouthpiece size using our FitKit app. Please expect this email a few minutes after successfully placing your order.

The FitKit app provides a simple and accurate way to measure your mouthpiece size, ensuring the best fit for your needs.
