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; used to make dentures; also referred to as "Waterloo teeth"; the dates listed for the teeth are five years before the Napoleonic War and five years after the American civil war; before this time dentures with human teeth were too expensive as good quality human teeth were hard to come by; the wars created an excess of human teeth available to the market and thus made the option of using human teeth in dentures more common; after this time the use of porcelain teeth in dentures was more common
