The Oral-B Smart Series 4000 3D White electric toothbrush combines cleaning technology with Bluetooth connectivity to the Oral-B smartphone app to give you real-time feedback on your brushing habits that can be adjusted by your dental professional. The dentist-inspired round head oscillates, rotates and pulsates to break up and remove up to 100% more plaque than a regular manual toothbrush while the specialized polishing cup removes surface stains for whiter teeth starting from day 1. The pressure sensor lights up if you brush too hard to prevent harmful over-brushing and there are 3 modes: daily clean, sensitive and whitening plus a timer to help you brush for a dentist-recommended 2 minutes.
