This souped-up electric toothbrush is the premium offering from Oral-B’s toothbrush line, technologically speaking. Right now, it’s at the best price we’ve seen in years and just a few dollars away from its lowest price ever.

This particular model is our top pick for best smart electric toothbrush, thanks to all the features and modes it offers, plus a useful app that gives you feedback on your brushing. Not only does it help remove plaque and surface stains but it uses AI to track your brushing and help you maximize it for the best results possible.

The brush comes with many smart features like seven clean modes and a display on the brush that helps you track your brushing time. Plus, it’ll give you personalized guidance on your teeth-cleaning so you become a better brusher along the way. Dentists’ own tools inspired the small round brush head, which helps you navigate each tooth and surface with precision. And if you’re someone who brushes a little too hard, there’s an indicator built into the brush head that turns red to let you know (it’ll turn green when you’re brushing with the right amount of pressure, helping you learn what works).
