Glamour commerce editor Malia Griggs is a big fan of her Oral-B iO smart toothbrush. “My dentist always gave me crap for brushing my teeth too hard,” she says, “until I started using my Oral-B toothbrush, which has pressure sensors to tell me when I’m brushing just the right amount. Take that, dentist!” It offers real-time feedback, seven cleaning modes, and other useful alerts to help improve oral care hygiene.
