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

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

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.

International buyer should be aware…

International buyer should be aware that Feno take 6 weeks to despatch. That is not a typo, I do not mean 6 weeks until you receive your package, I mean 6 weeks until they actually send it. Apparently it takes this long to 'process' an international order, and this is classified as 'Priority Shipping' and is what will cost you an extra £25. So all the website claims about free shipping, that is not for you, that's for people in the US. I ordered mine a month ago and the shop.app tracking has literally done nothing since placing the order. Every day I get spam emails telling me how great it is, how great they are, how they are changing the world, but it doesn't feel that great as a customer sat waiting, and no-one will explain to you why it takes 6 weeks to post a toothbrush.

Thank you for taking the time to share your experience — and we’re truly sorry for the frustration this has caused.

You’re absolutely right to expect clear timelines and transparent communication, especially when ordering internationally. We did experience an unexpected inventory delay that impacted some international orders, and we sincerely apologize that this wasn’t communicated to you more clearly.

To clarify, the 4–6 week timeframe for international orders includes processing, packing, and delivery time. “Priority Shipping” refers to the expedited service once the package has been dispatched by our shipping provider — but we understand how this can feel misleading if your order hasn’t yet left our facility. That’s on us to explain better.

We’ve now prioritized your order, and it is being prepared for shipment as soon as possible. Our team will also reach out to you directly with an update so you’re not left wondering what’s happening.

We know waiting six weeks to receive something you’re excited about isn’t the experience we aim to deliver. At Feno, we’re building something new in oral health, but innovation should never come at the cost of clarity or customer care. Thank you for holding us accountable — and again, we’re sorry for the delay.

We appreciate your patience and the opportunity to make this right.

I had a very disappointing experience…

I had a very disappointing experience with this company.

I requested to cancel my order before it was fulfilled and clearly explained the reason when asked. After that, communication stopped. Emails were not answered, and when I tried calling, no one picked up. Instead, I received an automated message saying phone support is unavailable and to contact them via text or email — which I had already done, multiple times.

Despite following their instructions and providing everything they asked for, I received no confirmation of cancellation or refund. I was forced to open a PayPal Credit dispute just to protect myself.

This experience caused unnecessary stress and wasted time. A legitimate company should not ignore customers once payment is made, nor make support inaccessible. I would strongly caution others before ordering.

Hi Harper — we’re truly sorry for the frustration you experienced. That’s not the experience we want for anyone.

We’ve reviewed our records but can’t locate an order under this name. Please note there are unaffiliated third-party sites selling products claiming to be Feno, which we are not connected to. That said, we genuinely want to help.

Our phone support is limited, which is why calls may route to email/text, and we understand how frustrating that can be. If you purchased directly from Feno, we’d like to investigate and resolve this properly.

Please contact us at support@feno.co with any order details or receipt so we can assist.

Feno is the best!

Feno has been excellent to work with. Not only is their product everything they promised (and more), but their customer service has been top notch! I can't recommend Feno highly enough!

A Promising Step Forward in At-Home Oral Healthcare

Feno has introduced a compelling new approach to at-home oral healthcare. The company's product provides a detailed analysis of oral health, moving beyond simple cleaning to a more proactive and informed approach to dental hygiene.
While the term "game-changer" may be premature, Feno's current technology is a significant step forward. It offers valuable data that empowers users to understand their brushing habits and monitor their oral health from home.
I am particularly fascinated to see how their future technology evolves as the company matures. The foundation they have built is solid and suggests a promising future for both Feno and the field of at-home oral health.

Great Product from a Great Company

I’ve been using the Feno toothbrush for several months, and I’m really impressed. It’s comfortable to use, gets my teeth cleaner than they’ve ever been, and makes the whole process quick and easy. The design is sleek and user-friendly and the customer service is outstanding. It’s not the cheapest option out there but, for me, the results are worth it.

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.

Even as a person with “buttons” while doing Invisalign this toothbrush is quite the arsenal in keep my teeth clean when I have to frequently pop aligners in and out. I can’t imagine how much time I’m saving! Additionally, my teeth are actually clean. Like — really clean. Cannot recommend enough.

Great toothbrush

Great toothbrush, brushes all my teeth on both sides all at once and my teeth feel better cleaned. The vibration seems to remove more plaque - my teeth feel more smooth. I also don't brush my gums too hard anymore with my new Feno.

Customer Service is outstanding

Customer Service is outstanding. The team is VERY responsive. Recommendations for improvement: 1. packaging of foam is unnecessarily difficult to open, 2. lack of included container for mouthpiece is unfortunate (and I heard they have them, but they're not able to be purchased because they're on backorder), 3. app interface isn't as user-friendly as it could be, 4. camera utility is technologically-limited (pictures are consistently "too dark" no matter the ambient lighting.)

Synergistic teeth brushing
