having your toothbrush coach you is absurd, but we really don’t teach people how to properly brush.
I looked it up a year ago and it turns out you just fuckin hold the head against the front, top, and back of each tooth, and raise it off the tooth before moving it to the next spot. Really we should just stop calling it “brushing” and instead say “polishing” because that’s what you’re doing.

If you brush it back and forth you’ll be fucking up your gums
