Jordon taught elementary school and worked as a
dental assistant while she was training to be a dentist in Berkeley, then opened her own dental practice in Los Angeles. At first she had a general practice; in 1909, she established the first dental practice in the United States devoted only to pediatric patients. She presented a paper, "Relation of Food to the Developing Teeth", at the 1921 meeting of the California State Dental Association, recommending fewer sweets and more milk, coarse grains, eggs, and vegetables in children's diets. As a "pioneer in
pedodontics" she published the first textbook on the subject in 1925, titled
Operative Dentistry for Children. She was an
associate professor of dentistry at the
University of Southern California, and an officer in the Southern California Dental Association. She was a founder and first president of the Federation of American Women Dentists and a founder of the American Society of Dentistry for Children. ==Personal life==
