Welcome to a time so long ago that people with no dental insurance still could get their teeth drilled, and perhaps filled. Flint-wielding specialists performed the work between 9,000 and 7,500 years ago.

The teeth came from residents of a prehistoric farming village called Mehrgarh in what is now Pakistan.
