Equipped with 18,000 bristles, the Feno Smart Toothbrush covers each tooth and the full gumline at once, reducing total brush time by 75%.
"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

- DGDenise G.Verified Buyer2 weeks agoRated 5 out of 5 starsThe best money you will ever spend
This device not only will change your life, it will save you time! It is get a dental cleaning every morning in 30 seconds! When I recently went to the dentist for my cleaning the hygienist looked at my teeth and said "well you didn't leave anything for me to do!" When the dentist came in to examine me he said "wow your teeth look great!"
I have never been told this at the dentist. I usually get comments like, "make sure you get the floss down by the gum line, or have you tried using a water pic?"
After I ate Thanksgiving dinner, I could still feel the smoothness of my teeth from top to bottom. So, I decided to tell everyone at the table! They said send me the link!
I actually had a problem with my first unit. I sent an email and Dani sent me out a brand new one within a few days no questions asked. Their customer support is phenomenal! I cannot think of anything negative about this product or the company! Run and buy one now!
Feno21 minutes agoHi Denise! Thank you so much for this incredible review! We're absolutely over the moon to hear about your amazing experience with the Feno Smartbrush. That moment when your hygienist said "you didn't leave anything for me to do" - wow! That's the ultimate validation and exactly the kind of transformation we love hearing about. It sounds like you've gone from getting the usual dental advice to having your dentist genuinely impressed, which is such a huge win!
We love that you're so excited about it that you're sharing it at Thanksgiving dinner and getting everyone asking for the link - that's the best kind of endorsement! And we're really glad that Dani was able to take care of you so quickly when you had that issue with your first unit. Our team works hard to make sure every customer has an amazing experience from start to finish.
Your enthusiasm is absolutely contagious and really means the world to us. Thank you for taking the time to share such a detailed and glowing review - it's customers like you who make what we do so rewarding!

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.
How does the Feno app provide personalized feedback and advice on oral care?
The Feno app uses data from your brushing sessions to help you understand your oral care habits over time. It tracks brushing activity and progress, then presents insights that help you see patterns in your routine and areas where consistency can improve. The goal is to support better daily habits through clear, easy-to-understand feedback rather than generic advice. Over time, this helps users stay aware of their brushing behavior and build more consistent oral care routines.
Is there privacy built-in with the scanner?
Yes, the Feno Smartbrush includes multiple built-in privacy features for the scanner. The device is equipped with a secondary privacy chip, ensuring that all operations related to the scanner are securely handled. This chip prevents remote access to the scanner, enhancing the security and privacy of the device. Additionally, all data collected by the scanner is encrypted, providing an added layer of security to protect users' personal information.
How do I know the mouthpiece size that is right for me?
To determine your correct mouthpiece size, please download our new app: 👉 Feno App (iOS)
Once downloaded, follow these steps:
- Log in using the email or phone number you used when placing your order.
- Locate the FitKit Scan button in the app.
- Follow the on-screen instructions to complete your scan. You only need to do this once.
Note: if you are using an Android device, reach out to our team to generate a unique webpage link to complete your scan.
This scan helps us determine the right size mouthpiece for you, ensuring a secure and comfortable fit that works effectively with your Smartbrush.
