If you're looking to clean your teeth thoroughly and would like some basic feedback about your brushing time and the ideal pressure when brushing your teeth, the Oral-B Smart 4 4500N is a good choice. This toothbrush provides immediate feedback about your brushing via a Bluetooth connection with your smartphone, which shows you very precisely which areas in your mouth need some extra attention. You can select 1 of 3 different brushing modes to improve your brushing performance. There's a setting for whiter teeth, for instance, and a setting for sensitive teeth. The toothbrush also has a pressure sensor, which prevents you from brushing too roughly, an interval timer, and a timer that indicates when you can stop brushing.
