Paleolithic Humans Got Dental Fillings, And They Weren't Pretty

Think a modern trip to the dentist is bad? Try one 13,000 years ago, where your filling contained the same material that we now use to pave roads—along with some hair and vegetable fibers. Desperate times call for desperate measures.

Back in 2015, Stefano Benazzi, an archaeologist at the University of Bologna, and a team of researchers published a paper on what they believed to be the earliest evidence of dentistry: tiny scratches from a flint tool made on a molar tooth dating back 14,000 years. In 2016, Benazzi and his team published another study that did that one better: newly discovered remains—these ones about a thousand years newer than the last—showed signs of a cavity filling. That establishes that these ancient people weren't just dabbling in dentistry—they were going all in and tackling cavities, too.

"It is quite unusual, not something you see in normal teeth," Benazzi told New Scientist. The teeth, which were upper central incisors (or buckteeth), had been drilled with sharp rocks and packed with fillings. The fillings were made with tar-like bitumen, a material that today is used mostly to pave roads, along with hair and vegetable fibers.

Which Came First, The Carbs Or The Cavities?

But before you feel too smug about the benefits of modern dentistry, consider this: before the Upper Paleolithic era in which the person lived, cavities were a lot more rare. Not long after this period, humans began growing grains, and the sudden uptick in carbs became a feeding frenzy for the bacteria in our mouth. That, in turn, may have contributed to the "dawn of dentistry."
