In the early part of the 19th century, dentures were made of a variety of materials, from wood and ivory, to real human teeth.
(Following the battle of Waterloo there was a plethora of spare teeth which had been extracted from the mouths of fallen soldiers. They became known as Waterloo teeth.
“Next to a battle lost, the greatest misery is a battle gained.” The Duke of Wellington)
