What it is

Origins and history
Traces of the practice appear in Japanese bones from the Kofun period. In Vietnam, archaeological finds date the custom to four hundred BCE. European explorers noted the habit in the sixteenth century. Colonial powers often disapproved of the practice. Western beauty standards eventually led to its decline. By the twentieth century, most communities had abandoned the tradition, though some isolated groups maintained it.
How it is kept
The process usually began with cleaning the teeth using betel, charcoal, and salt. A sour mixture prepared the surface for the dye. Burnt coconut shells or iron solutions provided the black color. In Japan, aristocrats used iron filings soaked in vinegar. The procedure was painful and caused gum swelling. Today, the custom survives mainly among older women or in cultural performances and festivals.
