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; dental silver is used in the creation of amalgam fillings, which consist of 40-50% liquid mercury mixed with one or more metals; amalgams were first used in France in the early 19th century, but the modern 'recipe' was perfected by Dr. G. V. Black in the 1890s in Chicago; the metal usually contains a high percentage of silver (around 70%) and a mix of tin, copper and zinc; high copper amalgams are also available, where the silver content is much lower (as low as 40%) and the copper much more prevalent
