Description
Masticator is made of two formed pieces of silver metal hinged by a single screw near the blades; object has a scissor like structure with two straight handles with a wood grip attached to the outside of each handle by two small gold coloured nails, one at the top and one at the bottom; the proper left handle hinges three quarters of the way up the handle; both handles curve outward at the top and lead to seven interlocking blades with three on one side and four on the other; the group of three blades are thicker than the group of four and are cerrated on the inside; the group of four blades have two thin straight blades on either side of the middle two which bend and touch at the top; the screw that holds the two pieces of metal together has a modified heart shaped handle; the object is held closed by a rectangular latch that is attached to the bottom of the proper left handle and sits in a groove on the outside of the proper right handle

Research Facts
Masticators were used to 'pre chew' food for people who had poor dentition or had lost some or all of their teeth; the use of the porous material as a grip on the handles suggest a pre-Lister fabrication date as his germ theory did not appear until 1860.

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
