Teeth filled 13,000 years ago in Italy

Researchers have discovered the world's most ancient dental fillings in northern Italy. The fillings were spotted inside a pair of 13,000-year-old front teeth and they were made of bitumen, a semi-solid form of petroleum. This is the earliest example of dentistry known to date. “It is quite unusual, not something you see in normal teeth,” said Stephano Benazzi an archaeologist at the University of Bologna.
