@sciencefunn: Research shows that ancient Maya civilization dentists, around 1,000 years ago (roughly 200–900 AD), carefully drilled into teeth to place decorative inlays made of jade, turquoise, and pyrite. To secure them, they used a durable, plant-based adhesive made from natural resins (like pine sap), oils, and other organic ingredients. This mixture appears to have had antibacterial and anti-inflammatory properties, which may have helped protect oral health. More recent studies, including work published in the Journal of Archaeological Science: Reports, found that these sealants contained over 150 organic compounds. Beyond holding the stones in place for centuries, some of these substances likely acted as natural disinfectants, reducing the risk of infection and decay. The Maya carried out these procedures using stone tools and abrasives such as quartz, with enough precision to avoid damaging the inner pulp or nerve—suggesting a detailed practical understanding of tooth structure. This type of dental modification was not just cosmetic, but also cultural, often associated with status, identity, and spiritual beliefs. Compounds identified in the adhesive include sclareolide (linked to Salvia plants), along with various plant resins and essential oils from the mint family. The fact that many of these inlays have remained intact for over a thousand years points to a remarkably high level of craftsmanship and material knowledge. We share wholesome science content.
