Vintage Hygiene Practices That Are the Very Opposite of Clean

 
Dying Teeth Black Was Seen as Beautiful

In the modern world, it is often encouraged to whiten your teeth, as this is a sign of cleanliness. However, this wasn't always the case. In fact, it was popular in Southeast Asian countries and Japan to dye your teeth black. Though it might look frightening to most people, they were covered in a glaze-like substance that was supposed to preserve teeth and prevent them from rotting. It was even believed to be extremely beautiful

Though this practice has mostly ended around the world, there are still a few places where this custom still exists. However, Western beauty standards would call this taboo.
