The Oral-B ProfessionalCare 1000 (formerly ProfessionalCare 7400) provides dentist-inspired cupping action in which a unique, round brush head surrounds each tooth for a tooth-by-tooth clean. The combination of high-speed pulsations and the oscillating rotating technology has been shown to reduce plaque and gingivitis more effectively than a regular manual toothbrush. It removes up to 97% of plaque from hard-to-reach areas, helps prevent and reverse gingivitis, and provides a deep and thorough clean.
