Your Sonicare toothbrush measures brushing motion so it can tell if you start scrubbing, which can be harmful for your teeth and gums. If you regularly scrub while brushing, the app will recommend that you enable the feature.
Once activated, the feedback light at the base of the handle will be amber and the toothbrush will vibrate differently. The light and vibration will return to normal when you stop scrubbing.
Note: your toothbrush does not have this feature activated automatically. To enable it, see "How do I turn the Scrubbing Feedback feature on and off?" within the FAQs.
The information on this page applies to the following models: HX9911/96, HX9992/22, HX9992/21.
