• A child’s baby tooth (labeled "Control Group A")
• A sliver of silver filling that matched his own
• And finally, a film negative of his six-year-old self strapped to a dental chair

The words "Project Mnemosyne" glowed under UV light.

They’d been erasing memories through toothpaste for decades.
