This brush helps you brush like your dentist recommends for 2 minutes with a professional timer. While you are moving the brush around your mouth, the Cross Action toothbrush head surrounds each tooth with bristles angled at 16 degrees and 3D Cleaning Action - Oscillates, Rotates and Pulsates to remove plaque better than a regular manual toothbrush. The brush has a 360-degree pressure control that protects gums and enamel. The triple pressure control stops pulsation, reduces speed and has a visual indication.
