Did you know that scientists studying decay inside an ancient wisdom tooth recently discovered the earliest known evidence of dentistry, dating back to the Paleolithic era?
Looking through an electron microscope, the scientists noticed a pattern of chipping and scratches that researchers say were made using a tiny stone pick.
Our teeth are pretty amazing!
