BREAKING: ICE AGE ROOT CANAL: Neanderthals Used Stone Drills on Cavities 59,000 Years Ago!

In a discovery that rewrites the origins of medicine, scientists have uncovered the oldest evidence of dentistry performed not by modern humans but by Neanderthals 59,000 years ago. A lower molar from Chagyrskaya Cave in Siberia’s Altai Mountains bears a precisely drilled hole extending deep into the pulp chamber — the unmistakable signature of an intentional “root canal” executed with stone tools.

Published in May 2026 in PLOS One, the study led by Kseniya Kolobova of the Russian Academy of Sciences and John Olsen of the University of Arizona details a tooth ravaged by severe bacterial decay and at least two cavities. Micro-CT scans and high-resolution 3D imaging revealed rotational striations and radial grooves that cannot be explained by natural wear, chewing, or post-depositional damage. The central perforation reaches the sensitive pulp, indicating deliberate removal of infected tissue to relieve excruciating pain.

The evidence is compelling because the team tested it experimentally. Using fine-pointed stone tools made from the same raw materials recovered in the cave — including jasper-like points — researchers replicated the exact hole, depth, and microscopic signatures on modern extracted teeth. A skilled experimenter achieved the result in under an hour through careful hand-held rotation. “Basically a root canal,” observed Olsen. Remarkably, the Neanderthal patient survived the procedure without anesthesia or antibiotics and continued using the tooth for years afterward, as shown by subsequent occlusal wear that polished the drilled surface.

This find demolishes the lingering stereotype of Neanderthals as brutish, instinct-driven cavemen. At a site already known for sophisticated lithic technology and evidence of close-knit family groups, the surgery demonstrates advanced anatomical knowledge, extraordinary fine-motor precision, pain tolerance, and — most tellingly — social cooperation. Someone had to steady the sufferer, keep their mouth open, and drill patiently into living, nerve-rich tissue. Such an act implies empathy, trust, and cultural transmission of medical know-how.

Until now, the earliest widely accepted dental intervention dated to about 14,000 years ago at Ripari Villabruna in Italy, performed by Homo sapiens with far less invasive technique. The Chagyrskaya molar pushes definitive operative dentistry back more than 45,000 years and proves it was practiced by another species entirely. Neanderthals were not merely surviving the Ice Age; they were actively innovating solutions to suffering using the simplest available technology.

As excavations continue in the Altai and new analyses emerge, this 59,000-year-old “Ice Age dentist” forces a profound reevaluation. The impulse to heal, to apply empirical knowledge against infection and agony, is not a recent human invention. It is a shared legacy stretching deep into our evolutionary past — one that Neanderthals practiced with a precision and courage that still commands respect across dozens of millennia. In the end, the drill marks on that ancient molar illuminate more than dental history; they reveal the bright spark of ingenuity that defines the human story long before recorded civilization began.
