Disclaimer: I wrote this post as an enthusiast for Dune: Part Two (2024) and the ‘seductively sick’ portrayal of Feyd-Rautha Harkonnen. Any other thoughts or comments are welcomed and appreciated! TL;DR: The aesthetic choice of Feyd’s blackened teeth aligns well with the widespread custom in ancient Vietnam — a sign of beauty, maturity, and even brutality. Read more below.

Teeth blackening in Dune: Part Two (2024) through the lens of Vietnamese culture
One thing that mesmerizes me about Feyd in the 2024 Dune movie is his blackened teeth. Not only does this provide an impressive physical appearance for Feyd, but it also reminds me of a long-lost fashionable custom in my home country.
Original inspiration. As far as I know, the film crew creatively invented this aesthetic for the movie from the inspiration of the black mamba (a type of venomous snake in sub-Saharan Africa) and images of geisha with black teeth. Similar to folklore and legends, other countries and ethnicities also dyed their teeth black with their local traditional recipes.
Vietnam-specific. Particularly in Vietnam, teeth blackening was once a popular aesthetic choice for both commoners and noblemen. As teeth blackening was a sign of elegance and decency, it was prevalent for Vietnamese women to adhere to this practice. This custom was deep-rooted as early as 400 BCE and grew so profound as an indicator of being ready for marriage or fierce on battlefields. Side note, Vietnamese people would not dye their teeth black until they came of age; it was indeed a statement of maturity.
A clash between the East and the West. It is also hilarious that until the early 20th century in Vietnam, white teeth were regarded as barbaric; only animals, savages, and evil spirits would have white teeth. During this time, one may casually make a sarcastic remark about pretty girls with white teeth such as “Oh you’ve got a pretty face but your teeth are as white as doggo.” On the contrary, in the eyes of the French colonists, the locals had impressive straight teeth but those were “as black as sewer pipes”.
Cannibalism? In some online discussions, internet users theorize that Feyd’s blackened teeth may indicate cannibalism. This fan theory is reasonable enough, because during World War I, to curb the abuse and bullying from the larger and stronger Moroccans and Senegalese mercenaries to the smaller Annamese counterparts, a French officer spread the rumor that black-toothed people were cannibals and could devour two legs in just an hour, terrifying the African mercenaries and bringing peace to the Annamese ones.
How to? So, without the privilege of wearing an Invisalign filled with black dye like Austin, how did the Vietnamese dye their teeth? In short, one must generally undergo the following stages to dye their teeth black: mouth sanitization, red dyeing, black dyeing, polishing, and maintenance, which on average took around three weeks. It was reported that the first teeth-dyeing session would rather be physically painful due to swelling mouth and lips, stinging sensation of the dyed teeth, and strict dietary restrictions (e.g., refraining from fatty and hot food, smoking).
On another side note, I don’t know exactly what the food that Feyd chewed in the early morning attacking Sietch Tabr and degrading Rabban, but to maintain the sheeny stylish black teeth, ancient and older Vietnamese often practiced betel nut chewing.
Dear Dune fan fic writers, please consider adding this long-lost social custom into your fics; multi-cultural representation would be greatly appreciated and respected.
Please let me know if you want me to delve into greater details of the teeth blackening tutorial in Vietnam. I may do a part two on this for my lovely Feyd and Vietnamese culture if you guys are intrigued!
