Maya tooth with jadeite filling
Researchers report the first known Maya dental filling made with gemstones: an occlusal jadeite inlay set into a molar, documented in a recent paper in the Journal of Archaeological Science: Reports. (labrujulaverde.com) The coverage cites work by Estuardo Mata‑Castillo, Andrea Cucina and colleagues describing the inlay’s material and placement. (labrujulaverde.com)
Researchers say a Prehispanic Maya molar contains the first known gemstone inlay placed on a chewing surface, not a front tooth. (sciencedirect.com) The paper, published in 2026 in the *Journal of Archaeological Science: Reports*, describes a lower left first molar with a green stone identified as jadeite or a similar material. The authors are Estuardo Mata-Castillo, Andrea Cucina, Marco Ramírez-Salomón, María Beatriz Monsreal-Peniche, Camilo Luin, and Elma Vega-Lizama. (sciencedirect.com) Maya dental inlays are already well documented, but they are usually found in visible teeth such as incisors and canines. A molar is different because it sits in the back of the mouth and is used for chewing, which makes a purely decorative explanation less obvious. (sciencedirect.com; sciencedirect.com) The report says the stone sits in the occlusal surface, the top of the tooth where food is ground down. That placement has led the authors to discuss a possible therapeutic purpose alongside the social or symbolic value jade carried in Maya society. (sciencedirect.com; historia.nationalgeographic.com.es) Archaeologists have spent years revising the idea that Maya tooth work was only ornament. A 2022 chemical study of ancient Maya dental sealants found plant resins and other compounds with properties that researchers linked to antimicrobial or medicinal use. (sciencedirect.com) Earlier clinical analysis also found that many Maya inlays were drilled with enough control to avoid the pulp, the soft inner tissue of the tooth. That pattern suggested skilled operators who could modify teeth without automatically destroying them. (sciencedirect.com) The same research area widened again in 2025, when another *Journal of Archaeological Science: Reports* paper described jadeite inlays in three permanent teeth with incomplete roots, indicating the practice could involve adolescents. That study said such cases had not previously been documented in the Maya world. (sciencedirect.com) This new molar does not settle why the stone was inserted. It does show that Maya dental modification reached farther into the mouth, and possibly farther into treatment, than the front-tooth examples that usually define the practice. (sciencedirect.com)
