The Oral-B Smart 4 is a true revolution in electric toothbrushes. Easily connect this toothbrush to the Oral-B app and get feedback while brushing. This way, you immediately know what to pay more attention to. In addition, the Smart 4 has a built-in timer that allows you to change brushing angle every thirty seconds for a total of two minutes. This allows you to remove up to 100% more plaque than you would with a regular toothbrush.
