This and Hunter's The natural history of the human teeth (No. 3675) revolutionized the practice of dentistry and provided a basis for later dental research. Hunter devised appliances for the correction of malocclusion. He described the various stages of inflammation of affected teeth, and gave an accurate description of periodontal disease. In the above work he included instructions with regard to the operation of tooth transplantation from one living person directly to the jaw of another. Hunter’s outstanding reputation made this highly dubious procedure more widely accepted than it should have been.
