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

- DGdante g.Verified Reviewer16 hours agoRated 5 out of 5 starsHappy with my Feno tooth brush
So far have had a great experience! It's a bit awkward at first but you get used to it very quickly. I always make up excuses to not brush my teeth, but with this I can't since it's so quick and kind of fun in a way!

- DGDenise G.Verified Buyer6 days 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!

I recently bought my Feno and have been very impressed with the level of customer service, Julius specifically, has been very helpful with any questions that I had and also very accommodating in getting me a mouthpiece that fits my mouth perfectly. Every response is always very prompt and informative... Not to mention, now that I have a great fitting mouthpiece I enjoy the device all the much more...
