Wisdom teeth are third molars that usually appear between the ages of 18 and 20 (although they may appear when older, or fail to appear at all). They are called "wisdom teeth" because they appear so late—much later than the other teeth, at an age where people are supposedly wiser than as a child, when the other teeth erupt. Often they need to be removed when they impact against other teeth—colloquially known as "coming in sideways". Wisdom teeth are sometimes described as an example of a "vestigial" trait. Some argue that r ...

Ivory is a hard, white, opaque substance that is the bulk of the teeth and tusks of animals such as the elephant, hippopotamus, walrus, mammoth, etc. Prior to the introduction of plastics, it was used for billiard balls, piano keys, buttons and ornamental items. The word "ivory" was traditionally applied to the tusks of elephants. Plastics have been viewed by piano purists as an inferior ivory substitute on piano keys, although other recently developed materials more closely resemble the feel of real ivory. Ivory - Struc ...

Teeth—singular tooth—are hard structures found in the jaws of many vertebrates. They have various structures to allow them to fulfill their many different purposes. The primary function of teeth is to tear and chew food and in some animals, particularly carnivores, as a weapon. The roots of the teeth are covered by gums. Teeth are covered by a protective structure, called the enamel, that helps to prevent cavities on the teeth. Adult teeth naturally darken as the person matures, the pulp within the tooth shrinks and dentin ...

Vagina dentata is Latin for toothed vagina. The myth of the vagina dentata in the Western world was popularized chiefly by Sigmund Freud, who found that it neatly meshed with his theories concerning castration anxiety. Freud bestowed this name on the phenomenon, inspired by a number of legends about women with vaginas which were supposed to contain teeth or other weapons, and with which they were supposed to be able to murder or castrate their sexual partners. The motif is contained in a number of myths from Asia, especially Southeast ...

Impacted wisdom teeth fall into one of several categories. Mesial impaction is the most common form, and means the tooth is angled forward, towards the front of the mouth. Vertical impaction occurs when the formed tooth does not erupt fully through the gumline. Horizontal impaction occurs when the tooth is angled fully ninety degrees forward, growing into the roots of the second molar. Finally, distal impaction is the least common form, and means the tooth is angl ...

The hedgehog is very effective in keeping tanks from getting through the line of defense. It maintains its ...

In Greek myth, dragon's teeth feature prominently in the legends of the Phoenician prince Cadmus and Jason's quest for the Golden Fleece. In each case, the dragon's teeth, once planted, would grow into fully armed warriors. Cadmus, bringer of literacy and civilization, killed the sacred dragon that guarded the spring of Ares. The goddess Athena told him to sow the teeth, from which sprang a group of ferocious warriors called the spartoi. He threw a precious jewel into the midst of the warriors, who turned on each other in an attempt to seize the stone for themselves. The five survivors joi ...

Dragon's teeth - World War II. Dragon's teeth (German: Höcker, "humps") were square-pyramidal fortifications of concrete used during the Second World War to impede the movement of tanks. The idea was to slow down and channel tanks into "killing zones" where they could easily be disposed of by anti-tank weapons. In practice, however, the use of combat engineers and specialist clearance vehicles enabled them to be disposed of relatively quickly, and th ...

The play has a complicated circular structure. It takes place in a modern setting, yet also includes moments of history. The characters are specific people, but they are also representations of historical or mythical figures who share a universal human experience. There are many references to Greek and Hebrew mythology, Western history, American culture of the 1930s and 1940s, as well as similarities to other works of literature, including James Joyce's novel Finnegans Wake. The play is performed mostly as a play within the play; however, the actors in the play within the play break character to address the au ...

Teeth and tusks have the same origins. Teeth are specialized structures adapted for food mastication. Tusks, which are extremely large teeth projecting beyond the lips, have evolved from teeth and give certain species an evolutionary advantage. The teeth of most mammals consists of a root and the tusk proper. Teeth and tusks have the same physical structures: pulp cavity, dentine, cementum and enamel. The innermost area is the pulp cavity. The pulp cavity is an empty space within the toot ...

In societies that have high sugar diets, tooth decay can damage teeth badly enough that they need to be removed. This leads to the creation of replacement teeth such as dentures and other tooth replacements. Some of the earliest artificial teeth were made by the Etruscans and their use was adopted in Ancient Rome for the wealthy citizens who often dined on food containing damaging sugars. ...

Velociraptor had strong jaws with rows of bladed teeth. These, in combination with large claws on their forelimbs and sickle-shaped talons on the second toe gave these animals some impressive weaponry. In 2005, a BBC documentary, The Truth About Killer Dinosaurs, created an artificial Velociraptor leg and sickle claw to demonstrate the claw's power - when tested on a pork belly, the claw failed to fully penetrate it, lending discredit to the popular notion of Velociraptor using the claw to disembowel its prey ( ...

When brushing the teeth, you first apply toothpaste to the bristles of the toothbrush. Then, holding the handle, you rub the bristles against the inner and outer surfaces of your teeth with up-and-down movements. You should continue this for at least three minutes. This vertical movement cleans the small pieces of food that get stuck in the gaps between the teeth and between the teeth and the gum. Rubbing with the shaft of the toothbrush is not recommended, except for cleaning the horizonta chewing surface of the molars (the rearmost teeth), as it would not b ...
