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; this item would have been quite cumbersome in the mouth, considering the weight of the metal; in 1864 the Goodyear Dental Vulcanite Co. was founded in the United States, producing dentures made with hardened rubber and helping them to become cheaper to make, lighter, easier to use, and thus more popular; they became more readily available once the Goodyear patent expired in the 1880s
