Toothworms

An 18th century hand-illustrated page from an Ottoman Turk dental book showing a molar infected with toothworms. As early as Babylonian times and lasting well into the eighteenth century, it was thought that a toothache was caused by worms. (The theory was disproved by Jacob Christian Schaffer in 1757.) These worms were depicted in art as dwelling with the demons of Hell and feeding upon the sinners. In a cavity on one side of the bisected tooth, Lucifer watches as two worms devour and entrap their victims. In the other half of the tooth, demons lord over a collection of human skulls.

This is an image of a piece of dentine acquired using a scanning electron microscope. It shows the dentinal tubules viewed after demineralization using etching with 37% phosphoric acid for 15 seconds and 10% sodium hypochlorite for 1 minute. The colors were obtained by mixing the signals of secondary and backscattered electrons. The mixing is performed using the software FEI Company.

Trevor Anderson: "Dental treatment in Medieval England"
British Dental Journal, No. 197 (2004)

Abstract: Medieval (12th–14th century) medical literature suggests that care of the teeth was largely limited to non-invasive treatment. Cures, mainly for toothache and ‘tooth worm’ were based on herbal remedies, charms and amulets. Bloodletting was advised for certain types of toothache. There is also documentary evidence for powders to clean teeth and attempts at filling carious cavities. Surgical intervention for oral cancer and facial fracture is also known. Post-operative infection and abscess formation can be identified and early forms of false teeth are mentioned.

  • An introduction to Medieval documents relating to dental problems is given.
  • Medieval herbal remedies for dental problems are outlined.
  • The earliest evidence for filling material is provided.
  • The earliest evidence for the manufacture of false teeth is presented.
