"Teeth preserve a record of their own," Professor Guatelli-Steinberg told Columbus Dispatch reporter Marion Renault. "It's almost like a fossil already, but in your mouth."

Enamel also preserves precious information about its owner, ready for scientists to mine. "There are a lot of clues in teeth," Guatelli-Steinberg said. Read the Dispatch article in its entirety here.
