Earliest Known Dental Work A total of 11 teeth from 9 adults who lived between 7,500 and 9,000 years ago contain holes drilled with sharpened flint points, according to a report in Science News Online. Flint-wielding specialists drilled holes, which are believed to have been filled with some type of material. The teeth came from residents of a prehistoric farming village called Mahrgarh in what is now Pakistan. (Source: Coppa, A., D.W. Frayer, R. Macchiarelli, 2006, Early Neolithic tradition of dentistry.
