The Oral-B Pro Limited rechargeable toothbrush provides a clinically proven superior clean vs. a regular manual toothbrush. The professionally inspired design of the CrossAction brush head surrounds each tooth with bristles angled at 16 degrees, and 3D cleaning action oscillates, rotates, and pulsates to break up and remove up to 300% more plaque along the gumline than a regular manual toothbrush. The pressure sensor stops pulsations if you brush too hard to prevent harmful over-brushing and there are 3 modes, plus an in-handle timer to help you brush for a dentist-recommended 2 minutes. Trust in the precision engineering of Braun and the dental expertise of Oral-B, the #1 brand used by dentists worldwide*. 100% Satisfaction Guaranteed. Do not use on children under age 3. Replace brush (head) every 3 months or sooner if the brush head becomes worn. *Based on surveys of a representative worldwide sample of dentists carried out for P&G regularly
