Brushing can be a lonely business, unless you are using Oral-B’s Bluetooth Connected Toothbrush. The communication between the toothbrush and smartphone gives real-time feedback, encourages you to properly brush the most important areas and tracks habits over time. The timer begins when the app detects the sound of your toothbrush running and will even tell you if you are brushing too hard. It’s great incentive to get the job done right!
