Toothworms and Spider Juice: An Illustrated History of Dentistry— Loretta Frances Ichord
Published by Millbrook Press, 2000.
Imagine that it is hundreds, or even thousands, of years ago, and you’ve got a terrible toothache. What would you do? For one thing, you wouldn’t even know what caused your pain. People once had the idea that toothaches were caused by toothworms, which thrashed about inside one’s mouth to cause pain and agony. Then, without a dentist to turn to, you’d have to try some home cures, such as donkey’s milk and other animal and plant remedies. Learn about these things and other ancient dental practices in this book, which features two-color illustrations and black-and-white photographs and period drawings. Find out how teeth were extracted and drilled without modern implements and anesthesia, learn about ancient surgeons and “tooth drawers,” and read the story of Apollonia, patron saint of dentists. From ancient dentures up to modern X rays, this history of dentistry is sure to intrigue even the squeamish reader.
