I really love the Feno and how effective it is at cleaning your teeth. I’ve been using it about three months now and even my dentist gave me a compliment on my teeth brushing regiment on a recent visit. I highly recommend it.

The product is great. My teeth and gums feel clean after using. They are responsive to any issues I might have.

The Feno Smartbrush gives my mouth a truly refreshed, clean feeling. The full-mouth bristles, along with the foaming toothpaste, feel like they really get in between every tooth and area of the mouth. After just 20 seconds, it gives the feeling of thorough brushing and flossing (similar to a post dentist visit), in one easy step. It makes me feel like I'm doing a good job caring for my oral health - especially as a busy mom where I don't always have time to prioritize self care.

Feno is such an innovative, yet simple solution to brushing your teeth! I truly feel like my teeth are squeeky clean after using my Smartbrush, and I feel like I'm saving myself time during my daily routine which is an added bonus.

We love hearing this—thank you! It’s awesome to know your Smartbrush is keeping your teeth squeaky clean and saving you time. That’s exactly what we designed Feno for—simple, powerful care that fits into real life. Keep enjoying the routine!

We don't think about the future of toothbrushes often, but thankfully, Feno did. If you had told me that my teeth would feel just as clean from a 20-second brush as if I had done a two-minute brush, I wouldn't believe you. However, now that I have a Feno smartbrush, I believe it. Not only that but there's a camera that keeps track of your oral health, providing useful information, not meaningless stats. Buying a Feno has been a win-win all around. My morning routine is more efficient, I know my oral health more frequently, and of course - my teeth feel great. I can't recommend Feno enough!
