Researchers in Texas are taking a new approach to autism research. They are studying baby teeth to find out more about the neurological disorder.

Donated teeth from children with and without autism are being ground up into powder then analyzed.

The process can reveal pesticides, plastics, even medicine a child was exposed to in the womb and as they grew, which may provide some clues to autism.
