Not sure if,”Caveman Dentist “, is my calling…but this is pretty cool!

A 59,000-year-old Neanderthal molar uncovered in Chagyrskaya Cave in Siberia's Altai Mountains provides the earliest evidence of intentional, invasive dental surgery in human prehistory. The study, published in PLOS ONE by an international research team, pushes back documented dental treatment by more than 40,000 years.
Evidence from the Chagyrskaya Molar
Precision Cavity Drilling: High-resolution micro-CT imaging revealed a localized hole extending directly into the tooth's inner pulp chamber—the nerve-rich area that causes intense pain when exposed to deep decay.
Microscopic Tool Marks: Microscopic grooves inside the cavity match experimental drill marks created using small, sharp stone picks made from locally available jasper found inside Chagyrskaya Cave.
Proof of Survival: The presence of subsequent chewing wear over the microscopic drill marks confirms that the individual survived the operation and continued using the tooth during their lifetime.
Hygiene Habits: The tooth also displays distinct horizontal grooves between the teeth, providing clear evidence of routine toothpick use to clear debris and relieve pressure.
Prehistoric Significance
Before this discovery, the oldest confirmed example of invasive dental surgery was a 14,000-year-old Homo sapiens tooth from Italy that had been scraped with a flint tool. Finding an intentional stone-drilled intervention in a Neanderthal molar from 60,000 years ago highlights that Neanderthals had the cognitive capacity to pinpoint the root cause of physical pain, the anatomical understanding to intervene, and the fine motor skills to execute delicate surgical care.
