How to use your Smartbrush

Get a better clean in less than half the time

Add Foam

Apply two pumps of Feno Foam to each side of the bristles. The xylitol-based micro-foam works into spaces that regular toothpaste can’t reach.

Position the brush

Your TrueFit Mouthpiece is sized to your mouth, so the bristles reach the front and back of every tooth. Press the button and relax.

Done in 20 seconds

Move the brush in circular motions for the most effective clean. Top and bottom, inside and out, you get the same thorough clean every time.

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.

    Customer service

    I had a great experience with Feno’s customer service. I called because I was having an issue (too big)with my mouth guard brush, and they answered my call very quickly. The representative was friendly, helpful, and resolved my issue without any hassle. They even sent me a replacement brush free of charge, which I really appreciated. It’s great to see a company that stands behind its products and takes care of its customers. Highly recommend Feno for both their quality products and excellent customer support!

    Great Brush - Better Customer Support

    This past year I wanted to improve my oral health and found the Feno brand and am very happy with my decision. Not only is the product great, but if I have any issues, when I reach out to customer support, I'm always able to resolve my issues. The 30 seconds or less brush leaves my mouth feeling clean, and after a year of using the brush, I've noticed a markable increase in my oral health.

    Awesome brush

    Feno brush is the next generation of dental hygiene. Customizable settings let you tweak the intensity to your liking. Teeth feel very clean with the foam toothpaste it comes with; it feels like I came out of the dental office every time I use the Feno brush, and it only takes 30 seconds to feel that way.

    I use the Feno brush in conjunction with manual brushing to get the best of both worlds.

    I hope to see the Feno brand constantly innovating, pushing the envelope for the dental industry.

FAQ

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.

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 TrueFit™ Mouthpiece and ArcFlow Tech™, ensures comprehensive cleaning, users should still follow a simple technique for optimal results. While the Smartbrush is on, it is recommended to move the TrueFit™ 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 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.

Does Feno work without the app?

Yes. The brush is fully functional on its own. The app just adds to it: tracking, coaching, and insights that help you get more out of every session over time.

What's included with Feno, and are there any ongoing costs?

Feno is a personalized-fit, motorized, sensor-equipped device that brushes your whole mouth in seconds. There are two consumables to plan for: Feno Foam, and a fresh TrueFit Mouthpiece we recommend changing every three months. Everything's listed upfront, so you always know what to expect.

Can I use my own toothpaste, or do I need Feno Foam?

You can use any toothpaste you like. That said, Feno Foam is built for the mouthpiece, it spreads evenly across all 18,000 bristles at once, so every tooth gets the same coverage in that 20-second clean. Toothpaste works; foam just works better with how Feno brushes.

What if the mouthpiece doesn't fit my mouth?

Feno doesn't ship one universal size. Based on your mouth scan, we match you to the right TrueFit Mouthpiece from our seven sizes, a personalized fit, not a one-size tray (which is exactly why older U-shaped brushes failed). If it doesn't feel right at first, it's often just seating: place it in gently with the device off, bite down softly, and wiggle your jaw so the bristles reach every tooth. Still not comfortable? Reach out to support and we'll resize you. Your first two size exchanges are free.

Am I locked into a subscription?

No. Feno Plus is optional and you can cancel anytime from your account. You can also buy refills of Feno Foam one off whenever you need them.

What if I don't like it?

Every order is covered by our money-back guarantee: you have 30 days from delivery to return it. For US orders we provide the return label; outside the US, return shipping is covered by you. Just reach out to support and we'll walk you through it. And because your first two size exchanges are free, an imperfect first fit never costs you anything.

Who is Feno not for?

Feno isn't the right fit for everyone. We don't recommend it for anyone under 18, anyone with active braces, anyone with a crown placed within the last 4 weeks, or anyone with a pacemaker. If any of these apply to you, we'd suggest checking with your dentist before ordering.
