Oral-B Vitality Precision Clean electric toothbrush provides a clinically proven superior clean against a regular manual toothbrush. The round shape of the Precision Clean toothbrush head is designed to clean tooth by tooth, and 2D cleaning action oscillates and rotates for better plaque removal than a regular manual toothbrush. There is one mode Daily Clean and a pressure sensor to alert you if you brush too hard, plus an in-handle timer helps you brush for a dentist-recommended 2 minutes.
