What's the history behind false teeth?

Due to modern science and technology, dentures today are largely indistinguishable from real teeth. This is not always the case. Perhaps the most famous fake-tooth American is the first president, George Washington. Washington's popular history can be described as wood teeth, though this is not the case. In fact, wood teeth is impossible. The corrosive effect of saliva soon turns into a paste-like pulp. In fact, dentures for the first president came from a variety of sources, including teeth extracted from human and animal carcasses.
