Results for "black teeth dyeing"

Quick answer

When did the custom of dyeing teeth black begin?

It is very difficult to pin down exactly when it started. The book Lịch sử Việt Nam (History of Vietnam, volume 1, Social Sciences Publishing House, 1971) records the tradition that a Văn Lang envoy answered the Chu king about the custom of dyeing teeth black, and writes that in the Hùng Vương era people dyed their teeth and chewed betel. Archaeologists have also found the teeth of ancient Vietnamese with black dye marks at the Đông Sơn culture site in Thanh Hóa, around the first millennium BCE.
