Discovery in Chagyrskaya Cave
A Neanderthal molar unearthed in Siberia's Chagyrskaya Cave, dated to 59,000 years ago, bears clear signs of a surgical procedure aimed at relieving tooth pain. The findings were published in the scientific journal PLOS One. Microscopic analysis confirmed that the hole in the tooth was created using a stone tool, not the result of decay. The tooth also shows wear after the procedure, indicating the treatment was successful.
Significance of the Find
This discovery reveals that Neanderthals knew how to treat toothaches some 40,000 years before Homo sapiens appeared. In Chagyrskaya Cave, researchers found a molar displaying traces of a surgical operation. According to the scientists, the hole led directly to the pulp and was too uniform to have been caused by natural cavities or chipping. The research team compared the marks on the ancient molar to those on modern teeth that had been drilled using replicas of stone scrapers.
Under the microscope, the marks on the ancient tooth matched those on the experimental samples, confirming their artificial origin. Microscopic scratches on the fossil tooth mirrored those made by a sharp stone point, reflecting the technology used at the time. The tooth also shows signs of antemortem wear, meaning the individual continued to chew with it for a long time after the intervention. The operation was successful—it did not lead to a fatal infection and likely provided relief.
This finding is significant because the earliest known evidence of dental treatment among Homo sapiens is much more recent. As a result, the research suggests that ancient humans possessed a considerable level of knowledge and skill in managing dental problems. Importantly, these facts point to the complexity and advancement of medical practices in early human communities.

It also challenges traditional views on the development of medicine, indicating that certain technologies may have existed far earlier than previously assumed. Such findings can reshape our perception of the evolution of medical knowledge in human societies and underscore the importance of studying ancient cultures for modern science.
