He told WXIA he started out collecting pulled teeth but decided toothpaste is, quote, "much more exciting." It's good that he switched because he displays his thousands of artifacts in his office. Imagine patients arrived instead to see thousands of teeth. Transcript provided by NPR, Copyright NPR.
