✗ The myth everyone repeats
George Washington wore false teeth made of wood, which is why he looked so uncomfortable in portraits.
✓ What is actually true
Washington's dentures were made from a variety of materials including ivory (hippopotamus and elephant), gold, lead, and human teeth, but never wood. The idea of wooden teeth is a persistent myth. His uncomfortable expression in paintings likely resulted from the actual dentures being ill-fitting and painful, not from wood.
