Research Facts
Dr Ralph and Mrs Olga Crawford donated their extensive Canadian dental collection to the DCF to create the museum in 1997; further donations were received while Dr Crawford was Curator Emeritus at the Dental Canada Museum until its closure in 2008; gold is still used by some dentists, despite it being more costly and more difficult to work with than amalgams or composites; gold was first used to fill cavities around 1500 C.E. in early modern Italy; while gold is a very soft metal, it becomes harder when compressed, and pieces weld together in the mouth; it requires twice as much force as amalgam does to be compressed, however, and there is a danger of hurting the tooth being filled
