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.

How Oral Health Impacts Body Health

Exposing the Mouth and Heart Health Connection

Almost half of people over 30 face gum disease, which can up your chances of serious heart problems.

Oral bacteria can trigger widespread inflammation

When your immune system responds to infection-causing bacteria in your mouth, it can cause inflammation throughout your body.

While that inflammation seeks to fight off the infection, it can contribute to vascular damage in your heart, brain, and other organs.

Cavities can contribute to arterial plaque build-up

Cavity-causing bacteria can enter the bloodstream and contribute to plaque formation and atherosclerosis — which increases your risk of stroke, heart attack, and heart disease.

While that inflammation seeks to fight off the infection, it can contribute to vascular damage in your heart, brain, and other organs.

    Really cool idea, and it works great. I wish there was a travel/carrying case available. And the app seems over simplified.

    Feno is clearly my last toothbrush!

    I'm loving it!! I've used 8-10 different electric toothbrushes of varying types (even two ‘similar’ 360-degree coverage types).Feno is clearly the last toothbrush I'll ever be purchasing (except for the second one I am buying for my weekend home)!

    The TrueFit Mouthpiece reaches all the gum lines perfectly, leaving all my teeth feeling noticeably cleaner then any other toothbrush. Feno's motor is much stronger than any of the other toothbrushes out there that I have tried, which I believe to be the critical factor contributing to its cleaning efficacy.

    Highly recommended.

    I adore the Feno Smartbrush!

    I adore the feno smart brush. The packaging was so flush. The initial connectivity was seamless. I have been using it purposefully and without any bother. I travel often and connecting to other WiFi is giving me a little trouble but I believe it is something that requires learning. I look forward to receiving the holder for the Smartbrush next year!

    Ive been using Feno Smartbrush for over a month now and the results have been great thus far! The brush cycle hits every surface of my teeth, and is quick for those days I have too much on my plate. The scan analysis is both concise and informative about my oral composition and hygiene, which is essentially the same as having a dentist in my bathroom! I enjoy this very much!

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.
