Neanderthal Dentistry: 59,000-Year-Old Tooth Reveals Earliest Known Dental Surgery

New research is fundamentally changing our understanding of prehistoric medicine. A recently analyzed Neanderthal tooth suggests that these early humans may have performed dental interventions nearly 60,000 years ago, a discovery that pushes the history of dentistry back by more than 40,000 years.

The study, published in the journal PLOS One, provides compelling evidence that Neanderthals possessed the cognitive complexity required to diagnose pain, select appropriate tools, and execute precise medical procedures.

A Discovery in the Altai Mountains

The specimen, identified as “Chagyrskaya 64,” is the lower molar of an adult Neanderthal. It was discovered in Chagryskaya Cave, located in the Altai Mountains of southwestern Siberia, Russia. This region was a known habitat for Neanderthal populations between approximately 49,000 and 70,000 years ago.

The tooth stood out from dozens of other specimens found at the site due to a deep, irregular hole in its crown. This chasm extended directly into the pulp chamber—the inner part of the tooth containing nerves and blood vessels. To researchers, the damage looked less like natural decay and more like a painful cavity that had been intentionally addressed.

Evidence of Intentional Drilling

What distinguishes this find from simple tooth decay is the presence of fine scratches around the hole. These marks suggest the use of a tool to manipulate the tooth. When combined with fine-pointed stone tools unearthed in the same cave, the evidence points toward a primitive form of drilling.

According to Ksenia Kolobova, an archaeologist with Russia’s Institute of Archaeology and Ethnography and the study’s senior author, performing such an operation was no simple feat. She noted that the process would’ve required the individual to “diagnose the source of pain, understand that removing decayed tissue could bring relief, deliberately select an appropriate stone tool and execute precise drilling with controlled finger movements.”

The wear patterns on the tooth further suggest that the procedure was successful enough to allow the individual to continue using the tooth for eating after the intervention.

Rewriting the History of Human Medicine

This discovery significantly disrupts the established timeline of medical history. Previously, the oldest recognized evidence of dental surgery was a Homo sapiens tooth found in Italy, dating back to about 14,000 years ago. The Chagryskaya 64 molar predates that record by roughly 45,000 years.

This finding suggests that the capacity for complex logical thought and medical intervention was not unique to modern humans. It implies that Neanderthals could identify infections and craft specific tools to alleviate physical suffering.

Scientific Perspectives and Skepticism

While the findings are groundbreaking, the scientific community remains engaged in a healthy debate regarding the nature of the tooth’s damage.

• Cognitive Implications: Matthew Skinner, a paleoanthropologist at the Max Planck Institute for Evolutionary Anthropology, noted that the discovery “provides insights on the cognitive abilities of Neanderthals.”
• Alternative Explanations: Not all experts are convinced the hole was man-made. Christopher Dean, an emeritus professor of anatomy at University College London, suggested that the hole could potentially be the result of an injury or other trauma. He also noted that the scratches might have been caused by a crude toothpick, a tool Neanderthals have been known to use.

Key Takeaways

• Discovery: A 59,000-year-old Neanderthal molar showing signs of dental work.
• Location: Chagryskaya Cave in the Altai Mountains, Siberia.
• Procedure: Possible intentional drilling of a cavity using stone tools.
• Significance: Pushes the known history of dentistry back by over 40,000 years.
• Implication: Suggests advanced cognitive abilities and medical reasoning in Neanderthals.

Frequently Asked Questions

How old is the Neanderthal tooth?

The tooth is approximately 59,000 years old.

Where was the tooth found?

The tooth was discovered in Chagryskaya Cave in the Altai Mountains of southwestern Siberia, Russia.

Does this prove Neanderthals were “smart”?

While “smart” is a subjective term, the research suggests that Neanderthals possessed complex logical thought. The ability to diagnose a problem, select a specific tool, and perform a precise physical task to solve that problem is a hallmark of advanced cognitive function.
