"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

"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.

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

    Feno is a game changer

    Was a weird 1st experience but it does what it's supposed to and in less time I might add. Once you get used to it, the Smartbrush really changes the game. Really glad I bought one.

    What a wonderful experience! Would recommend.

    This is a good investment for those who doesn't have much time on their hands and would like the pleasure of not stressing out over a simple thing in the mornings. It's going great and I can see myself using this for years. My dentist is very happy the last time I visited and I used the brush for a couple of months that time. Customer service is great too. Product is great. Overall great.

    Great Product - Fast & Easy

    Well you would not think that a toothbrush could be reinvented to the point where you would say it is groundbreaking. But . . . the Feno is just that! Very simple to use and the it makes thorough brushing fast and easy. The brush has a simple interface without complicated 'guidance' on how to brush and where to focus. In less than a minute your teeth are very clean. Simple, smart and great results. It deserves even more than 5 stars! Also, the foam is very easy to use and effective and compliments the simplicity of the device.

    First Impressions

    Very well packaged and presented on arrival - High Tech image. Only crazy thing is the tubes containing the foam are impossible to pull open! I tried all four that I had and all of them were stuck fast! One assumes they should pull apart or twist open. In the end I carefully used a craft knife to get in, worried about puncturing the bottle. My recommendation is to cut carefully around the beige disk at the top of the tube (see photo, the bottles don't arrive looking like the pic in the Founders Edition).

    The sizing for the mouthpiece is done easily before placing the order. In use it's really quite strange the first couple of times but one gets used to the method of using it. And it works in the 20 seconds well, teeth feel clean, though not as 'tingly clean' as using regular toothpaste and brushing for longer. But I like the process. Only been using it a week and a little concerned that the first bottle of foam is almost empty - the Feno web site, I see today, says three bottles is good enough for three months. And I have been what I call frugal in applying the foam to the brush. So the cost of ownership may turn out to be higher in running costs. I'll monitor carefully my use of the next full bottle and update this. So far, apart from the comments above, I like the device, it's fun to use and very time efficient and really feels like it's covering every part of every tooth. Might need to reduce the 5 stars if the Foam is not as economical as they suggest! Currently I'd…
