Oh yay, I get to address my two favorite common misconceptions about the colonial US at once.

There is an element of truth in the assertion that Ben Franklin owned slaves, but it's mostly untrue. He participated in what he was taught to do from an early age, but seeing the effects of slavery first hand changed his mind. He spent the rest of his life as one of that era's most outspoken critics against slavery, even purchasing a printing press to print anti-slavery brochures and pamphlets.

George Washington's wooden teeth are a myth. Wood teeth certainly existed, but were extremely uncommon and only used by people who had nothing else. Most commonly, dentures of that era were made from ivory, animal teeth, or cadaver teeth.
