Product Expert electric toothbrushes

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.
