In contrast to current era of of having sparkling white teeth as a trend, there’s one practice that stands out for its cultural uniqueness and historical intrigue: **Ohaguru** **What Is Ohaguru?** _Ohaguru_ was a traditional Japanese custom of **blackening one’s teeth** rather than whitening them. This striking dental trend was especially popular among aristocratic women (and sometimes men) up until the late 19th century. In old-century Japan, blackened teeth were considered elegant, a symbol of maturity, and even an indicator of marital status or social standing. ![Ohgaru](https://canada1.discourse-cdn.com/flex033/uploads/medbound/original/2X/5/5845c356a1bdec64fc9d684bed9ce3fc97577352.jpeg) ### **How Did It Work?** To achieve this deep, glossy black color, people applied a dyeing mixture to their teeth. The ingredients varied but often included iron-based compounds and acidic substances like vinegar, combined with colorants such as tea. This mixture bonded with the teeth, creating the distinctive dark shade. ### **Beauty, Culture, and Health Beliefs** Unlike today’s emphasis on _white teeth_ as the beauty ideal, Ohaguru represented a very different aesthetic. It was deeply woven into cultural norms—appearing in art, literature, and even marriage rituals. The practice wasn’t just cosmetic; many believed the coating could help **protect teeth from decay** , much like a natural sealant, though modern research suggests it may have been associated with gum inflammation and periodontal issues. ### **Why Did It Fade Away?** Ohaguru began to decline and was eventually outlawed in Japan in **1870** during Meiji Restoration as Western dental aesthetics and modern oral hygiene practices became more widespread. When white, clean teeth became the global ideal, the practice of blackening them fell out of favour despite its long cultural history. ### **Did Ohaguru Influence Dentistry Today?** Interestingly, traditional practices like Ohaguru have indirectly influenced modern dental science. Some historic observations about blackened teeth and protection from cavities contributed to the development of treatments like **silver diamine fluoride (SDF)**—a modern dental solution used to help prevent tooth decay, especially in children and vulnerable adults. * * * ### **Final Thoughts: A Smile That Transcends Time** Ohaguru reminds us that what we consider “beautiful” or “healthy” isn’t universal—it’s shaped by culture, history, and personal values. From ancient dental dyeing rituals to today’s meticulous oral hygiene routines, humans have always cared deeply about their teeth in fascinating and varied ways - What do you think of the idea of blackened teeth as a beauty standard? - Would you ever try a historical dental practice like Ohaguru if it were safe and reversible?

It was interesting to know about this for the first time. But I do think our teeth naturally exhibit white colour, so we should just take care of them as they are naturally and not fall behind any beauty standards. Also the application of acids like vinegar, it just decays the tooth. ---

This is interesting.😀 Black teeth and beauty definitely don’t go hand in hand in the modern world. Yet it was practiced meticulously in Japan until late 19th century is astonishing. 😳 🖤 🦷 Personally, I would not opt for it 😑 or maybe give it a try staying indoors, could be fun 🤔 😄 if it was safe and reversible. ---

I did hear about certain traditions like this from eastern part of the world but didn’t know it was called Ohaguro . Interesting name for an interesting custom . I wouldn’t try it though 😅🤣 because I’m happy with my white teeth and would like to keep them that way . When I read about practices like this I’m reminded of this one tradition where the gap between the upper two central incisors is considered beautiful and lucky in certain communities. What is beautiful and desirable to some might be ugly to others. [Next page](https://www.medboundhub.com/t/ohaguru-the-ancient-japanese-dental-trend/15461.md?page=2)
