How do astronauts brush their teeth in space?

Updated: Feb 25, 2021

Q: How do astronauts brush their teeth in space? A: As you’d expect, brushing your teeth in zero gravity is a complicated process! In an article on the Gizmodo website, astronaut Leroy Chiao explains some of the challenges. “It is unbelievably easy to lose things,” Chaio writes. “Get distracted for a moment, and that toothpaste cap is gone! Even if you are good about anchoring such things behind a rubber bungee, some rookie going by could knock it loose.”

But despite all of the difficulties, astronauts in space do still take care of their teeth… So those of us here on planet Earth have no excuse!
