"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.”

With electric toothbrush
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.
Gum Disease Affects the Brain
Almost half of people over 30 have gum disease, upping the risk for major brain disorders. Here's why and how to fight back
Gum disease increases risk of developing Alzheimer’s
Individuals with periodontal disease face up to 70% greater risk of developing Alzheimer’s than individuals with healthy gums.
Oral infections also caused memory decline 6x faster than those with healthy gums in just a six month period.
Periodontitis increases risk of anxiety and depression
Individuals with periodontitis have a 37% increased risk of developing anxiety and a significantly higher risk of developing depression.
Periodontal Disease Can Increase Blood Sugar
Nearly half of adults 30 and older have some form of periodontal disease, and research suggests a toxic two-way relationship between gum disease and diabetes. Here’s why — and what you can do about it
Periodontal disease can increase blood sugar
Infections from untreated gum disease can lead to a rise in blood sugar — which can contribute to or exacerbate diabetes
Gum disease and diabetes perpetuate one another
Dentists have long known that diabetes increases the risk of periodontitis — and now understand the relationship is a two-way street.
Gum inflammation negatively impacts glycaemic control. The two feed off of and worsen each other.

Gum Disease and Preterm Birth: The Hidden Risk
Maintaining good oral hygiene during pregnancy is essential not only for your health but also for your baby’s development. Discover the critical connection between oral care and pregnancy outcomes.
Why Oral Care is Essential During Pregnancy
Oral health plays a vital role in pregnancy. Hormonal changes can exacerbate gum issues, leading to potential complications like low birth weight. Regular dental checkups and proper oral care are key to a healthy pregnancy.
How Gum Disease Can Raise Your Risk of Developing the Deadliest Cancers
Nearly half of adults 30 and older have some form of periodontal disease, and research suggests a strong correlation between gum disease and several forms of cancer. Here’s why — and what you can do about it
Gum disease is associated with lung cancer
Several studies have corroborated this emerging belief, including one that found a 24% increase in lung cancer risk for patients with severe periodontal disease
Gum disease and diabetes perpetuate one another
High levels of fusobacterium nucleatum, a periodontal pathogen, is often foundin colon cancer tissue, suggesting a link between America’s second-deadliest cancer and this oral bacteria.

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!
- EEarnestVerified Buyer3 weeks agoRated 5 out of 5 starsSmart 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.

- DGDenise G.1 month agoRated 5 out of 5 starsIt's like getting a dental cleaning! Everyday!
I love my Feno! My dental hygienist said I left her with. Nothing to clean! She did. A little scraping here and there but said overall my teeth looked fabulous! So did the dentist! They said keep on doing whatever you're doing . I told them I was using the Feno. They said well it's doing a great job. I think Feno may take over dental cleanings someday!

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.
