Short description: Visible gum pressure control: if you brush too hard, the brush stops vibrating, slows down, and visually warns you by turning red to protect your gums. The round cleaning head adapts to each tooth. Rechargeable toothbrush with a convenient long-lasting lithium-ion battery and a charge level indicator. The Oral-B head changes color from green to yellow depending on individual use, indicating when it’s time to replace it to maintain 100% cleaning efficiency. Exclusive Oral-B 3D cleaning technology: rotates and pulsates to remove up to 100% more plaque than a regular toothbrush.
