Brush to reduce major disease risks
"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.
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

With electric toothbrush
Even when using the most advanced electric toothbrushes, people often miss areas of the mouth or brush inconsistently and not long enough — all of which adds up to plaque build-up.

The Feno Smartbrush significantly reduces the likelihood of human error, achieving near-complete plaque removal and a consistent full-mouth clean in just 20 seconds.
The Feno Smartbrush's scanning tech can give you insights into your tooth and gum health, and identify potential plaque build-up and inflammation. Your results are compiled into a detailed, actionable Oral Health Report shared with our Oral Health Coaches for at-home oral health consultations.

Leveraging a database of 20,000 dental profiles
Your unique measurements are analyzed by an AI model built on a database of 20,000 oral scans.

- 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!

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.

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.
If you have any questions or need further assistance, please do not hesitate to contact our customer support team at support@feno.co.
