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; believed to have been a dentists demonstration model; ivory was a common material used in the manufacture of dentures in the 18th century; a down side to ivory is that it degrades quickly in the mouth resulting in bad breath and a bad taste in the mouth; human teeth were preferred as they did not degrade like ivory or were too white like porcelain
