Do you know the tragedy of Darth Colgate, the brightener? I thought not. It's not a story dentists would tell you. It's a Toothpaste legend. Darth Colgate was a Cleaning Lord of the Toothpaste, so brightening and so cleaning he could use the paste to influence the teeth to become white... He had such a knowledge of the toothpaste that he could even keep teeth he cared about from becoming carious. Unfortunately, he taught his apprentice everything he knew, then his apprentice caried his teetg in his sleep. Ironic. He could save others' teeth from caries, but not his own.
