The idea of a tooth worm is a theory 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 Once widespread, the belief is now obsolete, having been superseded by more scientific rationales.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. [1]
The most common symptom is the complaint of sensation of a worm moving around the mouth, near the lips, and in the soft palate area. This movement is normally engendered by immature adult female worms. Symptoms, once noted, may continue from a month to a year if the worm is not surgically extracted. Eosinophilia is noted in some patients.
A Sumerian text from 5000 BC describes a "tooth worm" as the cause of caries. [165] Evidence of this belief has also been found in India, Egypt, Japan, and China. [160] Unearthed ancient skulls show evidence of primitive dental work. In Pakistan, teeth dating from around 5500 BC to 7000 BC show nearly perfect holes from primitive dental drills ...

Once the blister bursts and the worm begins to emerge, the wound is soaked in a bucket of water, allowing the worm to empty itself of larvae away from a source of drinking water. [15] As the first part of the worm emerges, it is typically wrapped around a piece of gauze or a stick to maintain steady tension on the worm, encouraging its exit. [15]
A. duodenale worms are pale grey or slightly pink. The head is bent a little in relation to the rest of the body, forming a hook shape – hence the name. The hook is at the front end of the body. They have well-developed mouths with two pairs of teeth. Males measure approximately 10 by 0.5 mm, and females are often longer and stouter.
There’s an invasive species of worm making itself known in Texas once again—the hammerhead flatworm. These worms are toxic, hard to kill, and dangerous to native critters like earthworms, but ...
Tongue worms grow by moulting, which suggests they belong to Ecdysozoa, while other work has identified the arthropod-like nature of their larvae. [12] In general, the two current alternative interpretations are: pentastomids are highly modified and parasitic crustaceans, probably related to fish lice, or they are an ancient group of stem ...
