A tooth (PL: teeth) is a hard, calcified structure found in the jaws (or mouths) of many vertebrates and used to break down food. Some animals, particularly carnivores and omnivores, also use teeth to help with capturing or wounding prey, tearing food, for defensive purposes, to intimidate other animals often including their own, or to carry prey or their young. The roots of teeth are covered by gums. Teeth are not made of bone, but rather of multiple tissues of varying density and hardness that originate from the outermost embryonic germ layer, the ectoderm.
The general structure of teeth is similar across the vertebrates, although there is considerable variation in their form and position. The teeth of mammals have deep roots, and this pattern is also found in some fish, and in crocodilians. In most teleost fish, however, the teeth are attached to the outer surface of the bone, while in lizards they are attached to the inner surface of the jaw by one side. In cartilaginous fish, such as sharks, the teeth are attached by tough ligaments to the hoops of cartilage that form the jaw.Monophyodonts are animals that develop only one set of teeth, while diphyodonts grow an early set of deciduous teeth and a later set of permanent or "adult" teeth. Polyphyodonts grow many sets of teeth. For example, sharks, grow a new set of teeth every two weeks to replace worn teeth. Most extant mammals including humans are diphyodonts, but there are exceptions including elephants, kangaroos, and manatees, all of which are polyphyodonts.
Rodent incisors grow and wear away continually through gnawing, which helps maintain relatively constant length. The industry of the beaver is due in part to this qualification. Many rodents such as voles and guinea pigs, but not mice, as well as leporidae like rabbits, have continuously growing molars in addition to incisors. Also, tusks (in tusked mammals) grow almost throughout life.Teeth are not always attached to the jaw, as they are in mammals. In many reptiles and fish, teeth are attached to the palate or to the floor of the mouth, forming additional rows inside those on the jaws proper. Some teleosts even have teeth in the pharynx. While not true teeth in the usual sense, the dermal denticles of sharks are almost identical in structure and are likely to have the same evolutionary origin. Indeed, teeth appear to have first evolved in sharks, and are not found in the more primitive jawless fish – while lampreys do have tooth-like structures on the tongue, these are in fact, composed of keratin, not of dentine or enamel, and bear no relationship to true teeth. Though "modern" teeth-like structures with dentine and enamel have been found in late conodonts, they are now supposed to have evolved independently of later vertebrates' teeth.Living amphibians typically have small teeth, or none at all, since they commonly feed only on soft foods. In reptiles, teeth are generally simple and conical in shape, although there is some variation between species, most notably the venom-injecting fangs of snakes. The pattern of incisors, canines, premolars and molars is found only in mammals, and to varying extents, in their evolutionary ancestors. The numbers of these types of teeth vary greatly between species; zoologists use a standardised dental formula to describe the precise pattern in any given group.[出典:Wikipedia]

🦷の文字を使った例文

歯を大切にすることは、健康な身体を維持するために欠かせないことです。歯は、食事を摂るために必要不可欠なものであり、不十分なケアをすると、虫歯や歯周病といった様々な病気の原因となります。 そのため、正しい歯磨きをすることが重要です。毎日の生活の中で、歯を磨く時間をしっかりととることが必要です。また、歯磨きの方法も重要です。正しい方法で磨かないと、歯垢や汚れが残り、虫歯や歯肉炎が進行してしまうことがあります。 近年では、歯医者さんによる口腔内の健康診断も重要視されるようになってきました。歯科医師による検査やクリーニングなどを受けることで、歯の健康を維持することができます。また、歯科医師は、歯並びの不良や歯の欠損など、美しさや機能性を向上させるための治療も行います。 しかし、歯の健康に関する問題は、虫歯や歯周病だけではありません。歯ぎしりや睡眠時無呼吸症候群(SAS)など、歯科医師が診察して治療できる様々な病気があります。これらの病気は、睡眠の質を低下させるため、日中の疲れや不調につながることがあります。 また、虫歯や歯周病は、口腔内だけだけでなく、全身の健康にも影響を与えることがわかっています。虫歯菌や歯周病菌が血液中に入り込むことで、心臓病や脳卒中など、様々な合併症を引き起こすことがあります。 以上のように、歯の健康は、身体の健康に直結する重要な要素です。日々の歯のケアを怠らず、定期的な歯科医師の診察を受けることで、健康な身体を維持することができます。🦷
