Manual vs electric toothbrush: which is better?
Angled bristles help remove more plaque even in hard-to-reach areas.¹
Longer bristles clean deep for gums that are up to 15x healthier in just 2 weeks.²
Triangular tips work to remove up to 100% more stains in less than two days.³
As you brush, SenseIQ technology senses pressure, motion, coverage and more up to 100 times per second. It then adapts the intensity if you push too hard. The intelligence of SenseIQ takes the guesswork out of brushing modes, so you can experience effortless care and better brushing over time.
