Three views of Neanderthal teeth showcasing ancient dental work
Ma’anshan City He County Culture, Tourism and Sports Bureau
A remarkable 59,000-year-old Neanderthal tooth discovered in a Siberian cave exhibits signs of intentional treatment for a deep cavity, marking the earliest known instance of dentistry, predating previous evidence by 45,000 years.
This lower second molar, suspected of harboring bacterial caries, shows distinct drilling marks made with a skilled stone tool that penetrated all the way to the pulp in three different stages. Although the procedure would have been painful, the patient likely experienced less discomfort and was able to continue using the tooth, according to Kseniya Korobova from the Russian Academy of Sciences.
<p>“Our findings challenge existing notions about Neanderthal cognitive abilities, demonstrating that they were capable of making causal connections about health,” she stated. “We have confidence in the evidence derived from our microscopic examinations.”</p>
<p>Located in the Altai Mountains of southwestern Siberia, where Neanderthals migrated roughly 70,000 years ago, researchers identified molars with irregularly shaped depressions partially overlapping the pulp chamber.</p>
<p>Initially, the research team speculated if the tooth was broken posthumously. As more scientists examined it, questions regarding its deformation arose. Previously, the earliest evidence of deliberate dental treatment was dated to about 14,000 years ago among <em>Homo sapiens</em> in Italy, where techniques involved scratching rather than drilling.</p>

<p>The team, including <a href="https://www.researchgate.net/profile/Lydia-Zotkina">Lydia Zotkina</a>, conducted in-depth analyses revealing clear indicators of human intervention. Enhanced imaging techniques unveiled cavities and abrasions consistent with repeated toothpick use, alongside marks from sharp stone tools that possibly originated from the same cave.</p>
<p>The cavity's shape suggests an attempt at restoration, likely with the aim of accessing the pulp chamber and removing tissue. The smooth contours of the teeth indicate they were still in use long after the drilling, Korobova noted.</p>
<p>"We began with skepticism," she remarked. "Gradually, we recognized we were uncovering something truly groundbreaking, rewriting an important chapter in Neanderthal history."</p>

<p>To further validate their findings, researchers conducted experimentation with various drilling and scraping techniques using a replica pointed jasper stone tool along with three additional stone tools. Due to the rarity and age of Neanderthal teeth, comparisons were made with molars from <em>Homo sapiens</em>—both modern and prehistoric. The team successfully created a similar cavity in just 50 minutes, emphasizing the need for precision and skill to avoid further damage.</p>
<p>"This was not an amateur attempt," Krivoshapkin stated regarding the Neanderthal case, emphasizing that the operators exhibited a sophisticated understanding of dental procedures. "They knew where and how deep to drill, reflecting remarkable cognitive and motor skills."</p>
<p>Neanderthals, as genetic evidence suggests, were more sensitive to pain compared to <em>Homo sapiens</em>. "The pain experienced would have been tremendous, leading us to believe that either the patient was remarkably stoic, the provider worked quickly, or perhaps both," he stated.</p>
<p>This invasive procedure likely resulted in nerve death, alleviating pain. "What we see here is invasive, intentional, and functionally effective," Korobova noted. <a href="https://www.unibo.it/sitoweb/stefano.benazzi/en">Professor Stefano Benazzi</a> from the University of Bologna expressed confidence in these results, highlighting the increasing evidence of Neanderthal sophistication. "Such discoveries indicate advanced cognitive and behavioral abilities beyond previous assumptions," he explained.</p>
<p>However, Benazzi cautions that this doesn't amount to advanced dental practices. "The pain must have been so intense that methods like rubbing the area were likely employed." He suggested referring to this phenomenon as 'proto-dentistry' or a similar term.</p>
