Connected devices are all the rage these days, and the toothbrush appears to be the latest to receive the treatment. The Oral-B Smart Series are a line of electric brushes that connect to your smartphone through Bluetooth 4.0, and give you the ability to track a number of brushing-related metrics. From how often, to how long, to how well you brush will be instantly visible on the app, and perhaps serve as a visual encouragement to practice better oral hygiene. The brushes themselves feature all of Oral-B’s abilities, such as 3D cleaning action and visible pressure sensor lights that warn you when you’re brushing a little too vigorously. Price and availability are unclear at this point.
