    It definitely makes the difference.

    ⭐⭐⭐⭐⭐

    I’ve had a very complicated dental history — years of braces, extractions, and ongoing challenges keeping up with oral hygiene. Because of that, I honestly didn’t expect any product to fit perfectly right away. But Feno has been a game changer for me.

    The device has made it so much easier to keep up with consistent brushing, something that was always difficult for me before. I may still need adjustments with the mouthpieces due to my unique dental situation, but overall this system has already reduced the stress of daily oral care.

    What I appreciate most is how much thought went into this project — it feels like a truly well-designed tool to make life easier. I’m still learning about all the features, but even just using it for brushing has been a huge improvement. Highly recommend.

    Wonderful experience!

    The Feno smart brush has been a game changer for me! I have a disability that makes brushing with a manual tooth brush difficult at times so I appreciate the ease of use of the Feno and I actually look forward to brushing my teeth now! I’ve definitely noticed a difference as well with the way my teeth look and feel!

    Smart brush

    I use my smart brush 2 to 3 times a day and it takes no more than 30 sec each time and my teeth are clean. My dentist compliments how clean my teeth are during my visits. This was a great investment.

FAQ

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.
