John G.C. Adams: father of Dental Public Health in Canada.

John Gennings Curtis Adams (1839-1922), Canada's first resident dental missionary, was the father of Dental Public Health in Canada. He established, personally funded and operated the first free dental hospital in North America for poor children and their mothers in Toronto from 1872, three years before the founding of The Hospital for Sick Children; he later became their first dentist of record. He was a visionary zealot for prevention of decay, dental education, and treatment over extraction.
