Why Dr. Smith Recommends Feno.
I recommend Feno to my patients because it removes the two biggest barriers to good oral care: time and technique.

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.
How does the Feno app provide personalized feedback and advice on oral care?
The Feno app uses data from your brushing sessions to help you understand your oral care habits over time. It tracks brushing activity and progress, then presents insights that help you see patterns in your routine and areas where consistency can improve. The goal is to support better daily habits through clear, easy-to-understand feedback rather than generic advice.
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.
How do I know the mouthpiece size that is right for me?
To determine your correct mouthpiece size, please download the Feno App (iOS). Once downloaded, log in using the email or phone number you used when placing your order, locate the FitKit Scan button in the app, and follow the on-screen instructions to complete your scan. You only need to do this once.
