4.3 SmarTimer and QuadPacer

  • The SmarTimer ensures you brush for the dental professional-recommended 2 minutes. The toothbrush will automatically turn off after 2 minutes.
  • The QuadPacer is a 30-second interval timer that indicates when to move to the next quadrant of your mouth, ensuring thorough cleaning.

4.4 Pressure Sensor

The built-in pressure sensor protects your gums and teeth from excessive brushing force. If you apply too much pressure, the handle will vibrate differently, and the light ring at the bottom of the handle may illuminate (depending on model variant) to warn you to reduce pressure.
