Experience Oral-B Smart 4, from the brand that brought you the first ever connected rechargeable toothbrush. The sleek white handle of the 4000 electric toothbrush improves your brushing habits. It seamlessly connects with the Oral-B app in your phone and guides you with real time feedback to brush better. While you are improving your brushing routine, Oral-B's unique round head does all the rest. It removes up to 100% more plaque than a standard manual toothbrush for healthier gums and it starts making your smile whiter as of the first day of brushing by removing surface stains. Not only this, but the toothbrush helps you protect your delicate gums with the proprietary pressure control technology that reduces brushing speed and alerts you to be gentler if you brush too hard. With the Smart Coaching you get from Oral-B Smart 4, 4000 toothbrush, you will improve your brushing habits and your oral health. No wonder Oral-B is the N1 recommended brand by dentists worldwide.
