After the Edo period, only men of the Imperial House of Japan and the aristocracy blackened their teeth. Due to the odor and labor required for the process, as well as a feeling among young women that they were aging, "ohaguro" was done only by married women, unmarried women who were older than 18, sex workers and geisha. For rural people, "ohaguro" was done only at times of special celebrations, such as Japanese festivals, wedding ceremonies, and funerals. There were also depictions of "ohaguro" in fairy tales, such as "Gon, the Little Fox".
