    Promising Results + Happy User

    I'm always on the lookout for a better 'brush' for my teeth - some are too hard, some are too soft, the electric ones have always died so quickly. I've been using the Feno toothbrush for a few months now and I have to say, it's changed my brushing habits - the timer and custom mouth piece make it so easy to use. I had my first dentist appointment since the switch and even they've noticed a difference! Customer support is also very responsive and helpful, which is hard to come by these days! I'm happy with the investment so far - highly recommend!

    Best idea I have seen for brushing my teeth. Staff has been helpful with questions.

    I asked for help with a new size brush head to better fit my teeth and was sent one in a very short time. Helpful advice too.

    Best investment

    I’m disabled and this is a lifesaver. I’ve tried many U or Y shaped brushes and this is by far the best. The base model has everything I need, but it’s made brushing my teeth fun and I love the foam toothpaste (I have tried many and this is my favorite. When you use this for 20 seconds it makes your mouth feel like you got back from the dentist and reaches places no other brush can. I’ve suggested this product to others already!

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.

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.
