The Oral-B Vitality Precision Clean rechargeable toothbrush delivers a thorough and effective clean. Pulsating to break up plaque, it rotates 7600 times every minute to sweep away up to twice as much plaque as a manual toothbrush. It features a 2 minute timer to assist effective brushing and comes with 1 Precision Clean interchangeable head. The Oral-B Vitality Precision Clean rechargeable toothbrush is also compatible with all Oral-B oscillating/rotating interchangeable toothbrush heads.Each Oral-B toothbrush head comes with a colored ring that fits on to the base of the replacement brush head. These rings come in a variety of colors allowing you to distinguish between different people’s brush heads if using the same toothbrush handle.Why use an electric toothbrush?Electric toothbrushes make brushing easier, as they provide the cleaning action for you. With a manual brush, you do all the work. An electric toothbrush can move thousands of times per minute, versus a few hundred for a manual brush. Oral-B sonic toothbrushes clean teeth thoroughly and are effective at removing stains from teeth. Many Oral-B electric toothbrushes have brushing modes for deep cleaning, sensitivity care, whitening, or gum massage. Oral-B oscillating/rotating electric toothbrushes use a dentist-inspired cupping action to clean tooth by tooth. Oral-B oscillating/rotating electric toothbrushes remove more plaque and reduce gingivitis more effectively (versus a regular manual toothbrush).
