Feno Reviews 67

MY FIANCÉE USED TO HATE BRUSHING HER TEETH
Now it only takes 30 seconds for a thorough brush. She is also a data nerd so the app lets her track all aspects of her dental health. Also, awesome team and staff who have been so helpful with support and user experience. 10/10 recommend.

This thing is actually awesome. At my last dentist appointment, I had my best gum checkup ever. Finding the right mouthpiece fit is easy. One thing I didn't know I would enjoy would be the time saving aspect of this toothbrush. Over the course of a week you save: 21 minutes, 30 day month: 90 minutes, Year: 1,095 minutes, which is 18 hours 15 minutes. That's a freaking win in my book. only complaint is the tooth paste. The straw does not reach the bottom making it difficult to get to the last part of the liquid.

I have been using my Feno tooth brush for about 4 months now and I have to say that I love this tooth brush. My dentist said that he has noticed improvements in the way my teeth look so that proves it works. I ended up buying 3 more for my family members. I highly recommend Feno above all other tooth brushes out there.

Excellent product! Have used other u-brushes and this one takes the cake. Next level product and next level customer care. You won’t be disappointed- definitely worth the money.

I LOVE my Feno. My teeth have never been cleaner and I bought one for my boyfriend. My mom just got one too. I think it's amazing. I just wish the tooth foam was more minty.

The Feno Smartbrush provides a 5 star brushing experience every time and I love it. I developed a very severe, mentally and physically draining OCD when brushing my teeth, and the Feno Smartbrush is definitely helping to snap me out of my intense daily brushing sessions.
Also, Feno Customer Support is absolutely world class, so you can rest assured that any issue will be dealt with promptly in a super professional and friendly manner.
Many thanks and all the very best to everyone at Feno for a brilliant invention and world class customer support :-)

Great product in theory, but falls short. Mouthpiece is very large and uncomfortable, and actually made canker sores in the back of my mouth from the friction of the mouthpiece the very first week.
Even turning the vibration setting to low for 20 seconds still create the same friction areas.

8/10 Cleaning. Often times will miss spots I can still feel plaque on. Sometimes need to brush twice in a row in order to get that clean mouth feeling and all of the plaque off.

The app 0/10. This is where the product falls short the most. Scans are simply photos of your mouth you take yourself. Wildly inaccurate! Used my product and it said I had multiple cavities, plaque, and tooth fractures on the first scan and more issues would pop up with each consecutive scan, giving me a lower dental score each time. And it doesn’t tell you specifically where these “lesions “are, only the side of the mouth they are located on. I immediately made a dental appointment and had none of those issues at all! The dentist actually saying that I had “superior dental .” The app created so much stress and made me super insecure about Poor dental health and negatively impacted my self-esteem for an entire three weeks.

Additionally, the fresh breath score is totally off despite using it for three weeks consistently 2 to 4 times per day I’ve never gotten over a 50/100.

Product OK at best, app is total garbage and if anything negatively impacts your overall well-being creating a false sense of insecurity.

I purchased the Feno Founder's Kit a while ago. Though I did not use the AI feature to scan your teeth and have a professional give you feedback on it, I appreciate the automatic 30-second U-shaped toothbrush function for a busy person like me.

Though people might judge a product like Feno to be gimmick or unnecessary, I find it as a premium addition to my oral healthcare. We only get one set of teeth in our lifetime, and I would like to think whether you, at first glance, judge the product as unnecessary or necessary, experimentation and self-assessment of the product is important to decide if it is for you.

For me, I found this product does the job for my needs of brushing quickly and getting to work or going to sleep paired with other oral care systems.

Give Feno a try!

Feno has genuinely changed my brushing routine for the better. It's faster and more thorough than traditional brushing — full mouth clean in 30 seconds or less, which sounds too good to be true, but here we are. Huge lifesaver on tired nights when two minutes feels like forever.

Customer service has been excellent too — Mona in particular was super responsive and helpful!

One thing worth knowing: regular non-foaming toothpaste doesn't really work with this brush, so stick to foaming formulas. I've been using nanohAP and fluoride toothpastes from other brands without any issues, but Feno's xylitol toothpastes are solid as well.

My only real hope for the brand is that they go after the ADA seal of acceptance next — it would go a long way in getting this awesome gadget into more homes, because it genuinely deserves to be there. Highly recommend!

I absolutely love my Feno electric toothbrush! From the very first use, I could tell this wasn’t your average toothbrush. The cleaning power is incredible — my teeth feel like I just left the dentist every single time. It removes plaque so effectively, yet it’s still gentle on my gums. I’ve noticed my teeth look brighter and my mouth feels fresher all day long.

The design is sleek and modern, and it fits comfortably in my hand. I also appreciate how quiet it is compared to other electric toothbrushes I’ve tried. The different cleaning modes are a huge plus — whether I want a deep clean or something more sensitive, it delivers perfectly.

Battery life is fantastic, and I don’t feel like I’m constantly recharging it. Overall, Feno has completely upgraded my brushing routine. If you’re looking for a toothbrush that truly makes a difference in your oral health, this is it. Highly recommend!

I love this tooth brush I been using for almost more than a year and having adhd helps with this toothbrush since I don’t have think about brushing since it does it all for me and I don’t have do nothing!

The toothbrush itself is incredibly convenient and easy to use. It makes daily brushing feel effortless and actually enjoyable. You can really feel how clean your teeth are afterwards.

What impressed me even more was their customer service. I had an issue with my machine, and they sent me a replacement for free without any hassle. That really shows how much they care about their customers and stand behind their product.

Great product, great support — highly recommended!

Feno is a game-changer in the realm of oral hygiene. It simplifies and expedites my routine, leaving my teeth exceptionally clean. Beyond its effectiveness, I highly value the attentive customer service provided by Feno. Whenever I encounter any questions or concerns, the customer service representatives are prompt and attentive. I wholeheartedly recommend investing in Feno for optimal oral health.

I am very happy with my Feno Brush. I wanted something advance in oral care and it seem that Feno is moving in that direction. Oral care starts at home, not when it’s time to go to the Dentist. Feno is changing the landscape on oral health.

Works great and speeds up my morning routine

The Feno works great my teeth feel clean and look white.

I recently used the Feno Smartbrush, and it’s completely elevated my oral care routine. The design is sleek and intuitive, brushing all surfaces at once and saving time without sacrificing quality. It leaves my teeth feeling dentist-clean in seconds. I appreciate the tech-forward innovation and efficiency—perfect for busy mornings or travel. If you value convenience, precision, and modern wellness tools, this smartbrush is worth the investment.

This has been the best brushing of my life my teeth feel cleaner and stronger than I've ever been I would recommend this to anyone who wants to fully feel what it means to have their teeth feel clean

I’M IN LOVE…with Feno AND my teeth now.

The product is AMAZING!

My teeth have never felt that “just left the dentist” feel before…unless I had just left the dentist 🤣

Brushing is so fast, it doesn’t apply the pressure I do brushing (thinking brushing harder will get a “cleaner” feel), my gums are getting proper attention (they don’t bleed & hopefully my gum recession will improve), and using the tongue scraper has become a daily routine since I now don’t brush it.
Thanks FENO!!!

Love this product. Who would have thought there could be an entirely new way to brush your teeth. They did it. It’s not only a new way but a much better way.
