A 59,000-year-old Neanderthal tooth found in a Siberian cave shows deliberate drilling marks used to treat a deep cavity, pushing back the earliest evidence of dentistry by approximately 45,000 years. Researchers used microscopic analysis and experimental replication with stone tools to confirm the intentional procedure, demonstrating sophisticated cognitive and motor skills among Neanderthals.
