Long before modern dental clinics existed, ancient Maya practitioners were using surprisingly sophisticated techniques to repair damaged teeth.
For decades, archaeologists have discovered Maya teeth modified with materials such as jade and pyrite. These dental inlays were often assumed to be primarily decorative, perhaps serving social, cultural, or ritual purposes. But a 2026 study of a Maya back molar containing a jadeite inlay suggests that at least some of these procedures may have had a therapeutic purpose.
Because the molar was positioned where the jade would not have been easily visible, researchers argue that the restoration was unlikely to have been purely cosmetic. 3D imaging also revealed calcification inside the tooth’s pulp, indicating that the individual was alive when the procedure was performed and suggesting the tooth may have been treated for damage or pain.
Even more remarkable was the material used to secure the jade. Researchers found evidence of an ancient organic cement containing calcium, phosphates, bitumen, and plant-derived essential oils. Some of these restorations have remained firmly attached for more than a millennium.
The findings reveal that Maya dental practitioners had developed remarkably durable restorative materials and therapeutic techniques centuries before modern dentistry.
