The Feno Smartbrush doesn’t use typical “vibrations” — it uses gentle translational movements designed to clean all teeth at once. That said, we know comfort is key, and you can customize the brushing intensity easily in the Feno App.
🛠 Here’s how to adjust the intensity:
Open the Feno App
Tap Settings (gear icon)
Select your connected Smartbrush
Choose “Brushing Speed”
Use the slider to lower or increase the intensity based on your comfort level
We recommend starting on a lower setting if you're new to Feno, especially if you have sensitive teeth or gums.
🔄 Not sure if it's working properly?
If the movements still feel uncomfortable or you see a “bite pressure” warning, make sure:
You’re not biting down too hard (the brush should glide, not press)
The Mouthpiece is seated correctly — it should feel snug but not forceful
You're using the recommended Mouthpiece size
If discomfort continues, reach out to support@feno.co and we’ll help troubleshoot or explore other Mouthpiece options.
