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; in 1864 the Goodyear Dental Vulcanite Co. was founded in the United States, producing dentures made with hardened rubber and helping them to become less expensive to make and thus more popular; porcelain was added to vulcanite bases to recreate the light pink colour of natural gums, since making the vulcanite the right colour weakened the denture
