| '''Teeth''' (singular '''tooth''') are small, [[wikipedia:en:calcification|calcified]], whitish structures found in the [[wikipedia:en:jaw|jaw]]s (or mouths) of many [[wikipedia:en:vertebrate|vertebrate]]s that are used to tear, scrape, and chew [[wikipedia:en:food|food]]. Some animals, particularly [[wikipedia:en:carnivore|carnivore]]s, also use teeth for hunting or defense. The roots of teeth are covered by [[wikipedia:en:gingiva|gums]]. Teeth are not made of bone, but rather of tissues of varying density and hardness. | | '''Category:Teeth''' — for a description of teeth, please visit the [[wikipedia:Tooth|Wikipedia article]] - avaliable in about 50 other languages, look at the list there. |

| Teeth are among the most distinctive (and long-lasting) features of [[wikipedia:en:mammal|mammal]] species. [[wikipedia:en:Paleontology|Paleontologists]] use teeth to identify [[wikipedia:en:fossil|fossil]] species and determine their relationships. The shape of the animal's teeth are related to its diet. For example, plant matter is hard to digest, so [[wikipedia:en:herbivore|herbivore]]s have many [[wikipedia:en:Molar (tooth)|molars]] for [[wikipedia:en:chewing|chewing]]. [[wikipedia:de:Carnivore|Carnivore]]s, on the other hand, need [[wikipedia:en:canine (tooth)|canines]] to kill prey and to tear meat.
