The AquaSonic Black Series Toothbrush changes the way you clean your teeth every morning and night, claiming to be able to remove up to 10 times more plaque than the manual toothbrush you're used to would. That means your chompers get some much needed TLC, while you do a lot less of the work.

This toothbrush offers the ability to customize your experience with four different modes: soft, whiten, massage, and cleaning. The 40,000 VPM motor is ready to help you whiten your teeth, and you could potentially see improvement in your gum health in as little as one week.
