Natural freshness you can feel good about

This toothbrush is so fast and convenient! This is perfect especially late at night when you don’t have the energy to use a regular motorized brush but don’t want to go to bed without brushing your teeth!

- JHJorge H.Verified Reviewer13 hours agoRated 5 out of 5 starsA game-changer
I have to say that I was skeptical. I’m an early adopter and I tend to get and try new emerging devices. The Feno toothbrush device is in the 10% of emerging tech that meets its promise and adopted it to be my official way of brushing my teeth. It is fast and my mouth is cleaner than ever. After four months of everyday utilization, it is not something I’m testing anymore and it is my daily official way of cleaning my mouth.

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.
With Feno Smartbrush™
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.
Does the Smartbrush need any user technique to work effectively?
The Feno® Smartbrush is designed to be user-friendly and requires minimal technique for effective use. While the advanced technology, including the TrueFitTM Mouthpiece and ArcFlow TechTM, ensures comprehensive cleaning, users should still follow a simple technique for optimal results. While the Smartbrush is on, it is recommended to move the TrueFitTM Mouthpiece in a slow circular motion. This motion helps to achieve optimal bristle contact with all areas of the teeth and gums, enhancing the brushing results.
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.
How does the Feno app provide personalized feedback and advice on oral health?
The Feno app revolutionizes personalized oral care by leveraging advanced technology and professional expertise. Embedded in the Smarthandle of the Smartbrush is a scanner that captures images of your mouth, including critical areas like the gumline, tooth integrity, and signs of inflammation. Once you complete a scan, the data is automatically synchronized with your profile on the Feno app. This seamless integration ensures that your oral health information is consistently up-to-date and readily accessible. The app then utilizes a dual approach for analysis: a network of licensed dentists and an evolving machine learning model. These dentists review and annotate your scans, providing valuable insights into your oral health status. Their annotations not only offer you personalized feedback and advice but also contribute to training our machine learning model. This model is designed to recognize patterns and deliver rapid, routine insights, enhancing the accuracy and effectiveness of the feedback you receive over time. Additionally, the app's chat feature allows you to directly communicate with a dentist from our network. This functionality enables you to discuss your scan results, ask questions, and receive expert advice, all within the app. You can easily share your scan data and reports with your dentist during these consultations, making the discussions more informed and productive.
Is there privacy built-in with the scanner?
Yes, the Feno Smartbrush includes multiple built-in privacy features for the scanner. The device is equipped with a secondary privacy chip, ensuring that all operations related to the scanner are securely handled. This chip prevents remote access to the scanner, enhancing the security and privacy of the device. Additionally, all data collected by the scanner is encrypted, providing an added layer of security to protect users' personal information.
