Throughout these convulsive centuries, which saw the emergence of a multitude of {{transliteration|ja|daimyō}} at odds with each other and led to the wars of the Sengoku period, samurai would take the heads of their enemies and collect them as trophies after battle to enhance their reputation in the eyes of their {{transliteration|ja|daimyō}}.<ref>{{cite book |last1=Thomas |first1=Louis |chapter-url=https://books.google.com/books?id=wExlaM1ov0sC&dq=ohaguro+samurai&pg=PA181 |title=Samurai: The Code of the Warrior |last2=Ito |first2=Tommy |publisher=Sterling Publishing Company, Inc |year=2008 |isbn=978-1402763120 |pages=181 |chapter=Chapter 5: Samurai at War}}</ref> The heads were identified and in many cases received {{transliteration|ja|ohaguro}} after decapitation to enhance the combatant's glory in defeating a notable enemy.

Each time the procedure was repeated, the teeth were carefully rubbed with the peel of a pomegranate to form an adhesive surface for the dye.<ref name=":3" /> According to Freeman-Mitford, the dye should be applied at most every two days, because even after the first day without a new coat, the teeth lost their lacquered shine and pieces of gray were mixed with those that maintained the desired black color, resulting in an undesirable appearance.<ref name="Freeman" />

The practice of teeth dyeing was very ancient in Vietnam, where it was considered a demonstration of maturity and readiness for marriage after puberty.<ref name=":2" /> It was also a demonstration of civilization, as there was an idea that white teeth belonged to animals, savages, and evil spirits,<ref name=":2" /> especially because of the presence of large protruding canines in all of them.<ref name="Southeast" /> The majority ethnic group in Vietnam, the Kinh, practiced this custom, as did various minority populations. Si La men painted their teeth red, while women painted their teeth black.<ref name=":2" /> These traditions declined in the 20th century, decade by decade with each new generation,<ref name=":6" /> although colonial medical reports from the 1930s stated that 80 percent of Tonkinese farmers had darkened teeth.<ref name=":6" />
