Outdated hygiene practices that are anything but clean

People Used to Brush Their Teeth with Crushed Mouse Brains

Modern toothpaste tastes minty and leaves a fresh sensation, but in ancient Greece and Rome, dental hygiene was far from pleasant. People used mixtures of ground bones, charcoal, and even crushed mouse brains to clean their teeth.

It’s hard to imagine the breath they must have had afterward. Although it was a common routine, this historical habit is not something anyone would want to revive.
