Redditor simsalapim built The Toothbrush Machine. It’s a robot that brushes your teeth! But only the front ones aka the only ones that matter. Molars are overrated! Simsalapim even provides a tutorial on how to make your own over at Instructables. I mean, if you trust the robot to only brush your teeth and not, like, I dunno jab you in the back of the throat with a toothbrush. Just sayin’, be careful! The word’s still out on what the 4 out of 5 dentists recommend, but this blogger suggests you trust no one. NO ONE!
