"I can just walk around getting stuff done, you know, turn on the alarm in the garage, get stuff ready at night. I've just got that thing vibrating in my mouth." His dental professional, Dr. Loud, confirmed the impressive results, observing that his "plaque levels, and then the inflammation is, like, gone now." He also adds "The first time I used the Feno, there was tons of crap all over the brush... I thought I'd been brushing well... it was almost like when you deep clean your car and a whole bunch of crap comes out from underneath the carpet."

“This isn’t just another toothbrush —it’s a game-changer in personal health care.”

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.

    Amazing

    This is the single best purchase I have ever made when it comes to personal care. My teeth and gums feel cleaner and better than ever. I actually enjoy brushing my teeth now. I travel a lot and battery life is more than good for at least a week of use. Ended up buying one for each member of my family.

    I've waited so long for this! Almost perfect.

    I've pledged in a couple of projects in the past. They had the idea but never able to bring it to life. When I found out about Feno, I was happy and skeptical because of my previous experiences. But I had to try. It looked more promising. They actually had the product. Besides my almost 6 minutes tooth brushing was getting in my daily routine. I had to try. So, i did. I ordered it. Not long after it came. In very nice packaging. Grade A presentation.

    Everything looks good and feels high quality. First I charged it with it's wireless charger. Then paired it with my phone. Super easy.

    What comes next might be little tricky for some. First, there is a getting used to time. At first, it's uncomfortable but that took couple of days. Apparently I scanned my mouth little wrong so I received bigger size brush. But not to worry. I have contacted them. No questions asked they sent me smaller the right size.

    My tooth brushing is down to 30 seconds. Like a magic. I didn't want to write this review until I visited my dentist. After my dentist checked everything, I asked him if everything is ok or ant change good or bad. He said everything is good and there is no problem at all.

    So, besides getting used to time, the product is great! Thank you Feno for saving my time in the morning.

    Incredible customer care by Mona

    I wanted to take a moment to recognize Mona for her truly extraordinary customer care. From the very beginning, she went above and beyond to assist me—not only with professionalism and efficiency, but with genuine kindness and attentiveness that made all the difference.

    Mona consistently followed up, answered my questions thoroughly, and made sure I felt supported every step of the way. It’s rare to come across someone who is not only excellent at what they do but also brings such warmth and sincerity to the experience.

    Feno is incredibly fortunate to have someone like Mona on their team. She represents the brand with such grace and care, and because of her, I will absolutely consider returning in the future. Her thoughtful service left a lasting impression, and I can’t thank her enough.

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.
