How does the pressure sensor feedback work on my Sonicare toothbrush?

Published on 31 March 2024

Your Sonicare toothbrush measures the pressure you apply while brushing to protect your gums and teeth. If you apply too much pressure, the handle will change its vibration. 

You will be alerted when you apply too much pressure. Depending on your toothbrush model, this can be by one or more of these signals:

  • Light at the toothbrush base.
  • The brush head reminder LED will flash.
  • A change in vibration and therefore brushing intensity.
  • A sound and/or a pulsing sound.

These signals will stop when you reduce pressure. 

If there is no pressure indication when you press too hard, contact us for further support.
