You can connect Oral B smart electric toothbrushes with app to a smartphone app. The Oral B app provides feedback on your brushing behavior. With this feedback, you can improve your brushing technique and ensure healthier teeth. While you brush, the app shows you exactly which parts of your teeth you brush well or should brush better. The app also ensures you spend enough time on each zone in your mouth. You also receive a notification when you're pressing down too hard. That way, you can protect your teeth and gums.
