Braun PRO1S Electric 2 Replacement Brush Black Oral-B Toothbrush, Tips, D305.523.3,

For those who want to easily experience Oral-B's 99.7% increased plaque removal power: Compared to manual brushing, the Pro 1 features a circular rotation and up-and-down vibration. [Designed to be gentle on gums by stopping vibrations when brushing too hard] If brushing pressure is too strong, the overpressure stopper automatically stops the up and down movement. [Unique "round rotation" + "up and down vibration" inspired by dental cleaning equipment] The unique round rotating brush knocks off plaque with "up and down vibration", and the round rotation wraps around each tooth, physically scraping away plaque that is difficult to dissolve in water. [Dentist-recommended 2-minute timer] The built-in timer vibrates every 30 seconds to ensure you brush each of the four sections of your mouth thoroughly. It also vibrates to let you know when you've finished brushing for the dentist-recommended 2 minutes. [X-filament brush] Reaches areas that regular brushes can't clean and thoroughly removes fine dirt. Included: 1 multi-action brush and 1 soft, ultra-fine bristle brush.
