Teeth blackening is a cultural practice found across Southeast Asia, Oceania, Japan, and parts of India. It marks the transition to adulthood and was historically viewed as a sign of maturity and civilization rather than mere aesthetics.
- Known as ohaguro in Japan, banned by government in 1870.
- Used iron filings and vinegar to create the black dye solution.
- Signified adulthood and beauty in Vietnam and Southeast Asia.
- Distinct from betel chewing stains which damage gums.

What it is
This practice involves staining the teeth black using various chemical agents. It serves as a marker for reaching puberty and entering adult life. The dark colour was associated with human distinction from animals and represented a high standard of beauty and civilisation in many societies.
History and origin
The custom appears in Japanese records from the Kofun period and Vietnamese archaeological sites dating to 400 BCE. In Japan, it was known as ohaguro and persisted until the Meiji era ban in 1870. In Vietnam, it was widespread until the 20th century, declining due to Western influence. Similar practices existed among tribes in Eastern India and various groups in the Philippines and Thailand.
What it means
Blackened teeth symbolised maturity, chastity, and social status. In Japan, married women and geisha adopted the look. In Vietnam, white teeth were linked to savagery or evil spirits, making black teeth a sign of refinement. The practice also carried sexual overtones in some South Asian contexts, relating to marriage rituals.
Styling and care
The process required cleaning teeth with charcoal and salt, followed by acidic preparations like rice wine and lemon juice. Dyes included burnt coconut shells, iron filings soaked in vinegar, or missī mixtures containing iron sulphate and tannins. Applications were repeated over several nights, often causing gum swelling.
In culture
Historical texts from Korea, China, and Europe documented the practice with fascination or disapproval. In Japan, it appeared in literature like The Tale of Genji. Thai kings used artificial dark wood teeth. The custom remains visible only in traditional performances, festivals, and among older generations in isolated communities.
