I believe you're referring to a structure called a Radula.
radula. The radula is a tongue-like organ equipped with rows of small, chitinous teeth that are used to scrape or rasp food particles off surfaces. It is primarily found in gastropods such as snails and slugs, but is also present in other mollusk groups like chitons and some cephalopods.
There are alot of widespread fossil organisms from the Paleozoic; -Brachiopods -Bryozoa -Trilobites -Corals -Crinoids -Gastropods -Nautaloids/Cephalopods -Ostracods -Scolecodonts Once you get to devonian you may be able to find shark teeth. After the Carboniferous, You can find plants, insects, and (rarely) reptiles. Hope this helped!

It is unknown of the type of parasites that are found on the teeth. The parasites could be from food that has been rotting between the teeth. Birds that are called a plover.
The radula is a tongue-like organ with rows of teeth that work like files. It is used for scraping and tearing food.
In your mouth cavities are found in your teeth if you do not look after them properly, these are called 'dental cares'.
Gastropods obtain food by crawling around and looking for it. When they find it, they use their radula (sharp teeth-like structures that rotate) to scrape food off of things. For example, if a gastropod finds some algae on a rock, they will use radula to scrape the algae off the rock. Gastropods do not chew they scrape things off and digest it.
dentine is found in the teeth
Bacteria found in groups called biofilms are found on the teeth. Upward of 300 different species of bacteria can inhabit the biofilms that form dental plaque.
The pointy teeth in the mouth are named "Canines" and are common among mammals, usually being enlarged in carnivores. Canine teeth can be found between the incisors and premolar teeth in mammals.
The element is found in your teeth is Calcium.
Dentin is a material found in teeth. The dentin material found in teeth is just under the layer of enamel.
