How can I adjust the vibration intensity of my Feno device if it feels too intense?

Updated over 2 weeks ago

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:

  1. Open the Feno App

  2. Tap Settings (gear icon)

  3. Select your connected Smartbrush

  4. Choose “Brushing Speed”

  5. 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.
