Created by a French dentist, Willo makes even the fanciest electric toothbrushes seem analog. Slip the nylon-bristle-lined silicon tray into your mouth, form a seal with your lips and turn it on. The $199 device—set for release in early 2021—pumps in water and specially formulated toothpaste, then pulls it from the tray through a tube into a sink. No rinsing required. The undulating bristles do the work of a team of toothbrushes, and the pumping action, which feels like a gum massage, is effective at removing plaque. Willo syncs with an app, so it knows how consistently you’re brushing. Missed a day? It’ll clean your pearly whites a little longer tomorrow. —Marjorie Korn
