Dyeing teeth is one of the ancient customs of peoples in some countries of Eastern Asia cultural region, such as China (in the south), Japan, Korea, Vietnam; however, history, meaning, and technique dyeing of each nation are different. In this article, we will present the custom of dyeing teeth of Vietnamese people.
According to legend, along with the betel chewing custom and the tattooing custom, the custom of dyeing teeth formed in the reign of Hung Vuong (2879 – 258). For a long time almost Vietnamese people from the poor to the rich, from the peasantry to the mandarins, the landlords, the royals, and the kings all dyed their teeth. Around 1862, when Western civilization strongly penetrated into Vietnam, and especially in the early years of the 20th century, this custom decreased and gradually disappeared.
The meaning of dyeing teeth
The custom of blackening teeth is first from an aesthetic point of view. In literature, the custom of blackening teeth and black teeth of women are praised as an indispensable beauty:
“Black teeth, who dyed for you?
Making our relationship beautiful, making me passionate.”(Vietnamese folk-song)
“Getting a husband deserves a husband,
No waste of making up pink cheeks, black teeth” (Vietnamese folk-song)
In addition to the aesthetic point of view, national awareness in distinguishing the two cultures of the South (Vietnam) and the North (China) is also the reason why Vietnamese people dyed their teeth. Being Vietnamese people whether male or female from 16 to 17 years old had to dye their teeth black. Those who left white teeth were despised because they are thought to be hybrids, folk often used the phrase “White teeth like Wu’s teeth” (Wu was a state belonging to ancient China). In the XVIII (1789), in Quang Trung’s call to fight the Qing army, there sentences:
“Beating it for long hair
Beating it for black teeth.”
