tooth worm

{{Short description|Erroneous theory of dental disease}}

File:Tooth worm.jpg

The idea of a tooth worm is a hypothesis of the cause of dental caries, periodontitis and toothaches. Once widespread, the belief is now obsolete, having been superseded by more scientific rationales. It was supposed that the disease was caused by small worms resident within the tooth, eating it away.{{cite journal |author=Gerabek WE |title=The tooth-worm: historical aspects of a popular medical belief |journal=Clinical Oral Investigations |volume=3 |issue=1 |pages=1–6 |date=March 1999 |pmid=10522185 |doi=10.1007/s007840050070|s2cid=6077189 }}

History

The origins of the belief are wrapped in obscurity.{{cite web|author1=The Chirurgeon's Apprentice|title=Bookmark the permalink.

"After Anu [had created heaven],
Heaven had created [the earth],
The earth had created the rivers,
The rivers had created the canals,
The canals had created the marsh,
(And) the marsh had created the worm—
The worm went, weeping, before Shamash, his tears flowing before Ea: "What wilt thou give for my food? What wilt thou give me for my sucking?"
"I shall give thee the ripe fig, (and) the apricot."
"Of what use are they to me, the ripe fig and the apricot? Lift me up and among the teeth and the gums cause me to dwell! The blood of the tooth I will suck, and of the gum I will gnaw its roots!"{{Cite book|title=Ancient Near Eastern texts relating to the Old Testament|url=https://archive.org/details/ancientneareaste00prit_316|url-access=registration|date=1955|publisher=Princeton University Press|others=Pritchard, James B.

Accounts are also found in the Central American legends of Popol Vuh. The belief persisted into the 18th century, only being disproven by the microscopical endeavors of M. Pierre Fauchard.{{Cite book|author=Pierre Fauchard|year=1728|title=Le Chirurgien Dentiste}} Modern veterinary practice shows that when removed intact, the necrotic or partially necrotic tooth pulp can have an appearance like that of a worm.{{cite web|url=http://www.veterinarypracticenews.com/is-todays-dogma-tomorrows-tooth-worm/|title=Is today's dogma tomorrow's tooth worm? - Veterinary Practice News|website=www.veterinarypracticenews.com}}

Evidence

Although no rigorous evidence was ever found, some practitioners{{Who|date=January 2025}} believed the pulpal tissue within the root of the tooth to be a worm. Most however admitted to have never encountered a worm in vivo, but nonetheless encouraged the belief among the general public.{{Citation needed|date=January 2025}}

A 2009 study by the University of Maryland Baltimore using micro imaging revealed worm-like structures within a dissected molar. While not worms or caused by worms, these structures may have given rise to the tooth worm belief.{{Cite web|url=https://www.sciencedaily.com/releases/2009/07/090727205901.htm|title=Do You Believe In 'Tooth Worms?'
