Gold was the most satisfactory material for making full or partial dentures because it could be fashioned accurately to fit well. However, this type of denture was very expensive. The process of shaping the gold was called swagging, and was carried out by hammering it over a model with a horn mallet. The human teeth, complete with their exposed roots, were drilled through the pulp chamber and riveted into place onto the gold. This is photographed to show the pins used to secure the teeth.
