It is a common misconception that George Washington had wooden teeth, as false teeth. He did, however, try many different ways to replace his teeth, including having teeth carved from elk's teeth or ivory. Ivory and bone both have hairline fractures in them, which normally cannot be seen, but started to darken due to Washington's use of wine. The darkened, thin fractures in the bone made the lines look like the grain in a piece of wood. George Washington's teeth started falling out when he was about 22 years old, and he had only one tooth left by the time he became president. It was difficult for him to talk or to eat. At one time, he had false teeth with a special hole so the one tooth he still had could poke through. He tried to keep them smelling clean by soaking them in wine, but instead they became mushy and black. In 1796, a dentist had to pull out George Washington's last tooth, and he kept his tooth in a gold locket attached to his watch chain. When the time came for the president to have his portrait painted, cotton was pushed under his lips to make him look as if he had teeth. The cotton made his mouth puff out, as is seen on the picture on the US $1 bill.
