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).
