Question

What do we call the type of teeth attached to jaw bones in which each tooth is embedded in a socket of jaw bones?

Answer 1

Hint: Teeth are hard structures present exclusively in all vertebrates. Some invertebrates are equipped with analogous “teeth,” but they are very different in their structure and features. There are several kinds of teeth found in humans. Vertebrates have teeth that differ in structure and numbers. These arrangements of teeth are stated through a special formula referred to as dental formula, which is denominated in the form of fractions.

Complete step-by-step anwer:
Humans and other mammals, including vertebrates, geckos, and reptiles are all categorised as thecodonts and diphyodonts.
Thecodont dentition is a dentition where the base of the tooth is enclosed in jaw sockets. The tooth is fixed in a socket of the jawbone. Ankylosis is absent and the roots are cylindrical. Examples are mammals and crocodilians.
Additionally, Diphyodont is a kind of dentition where two consecutive sets of teeth are developed during the lifespan of the organism. The first set of teeth is deciduous, and the other set is persistent. Permanent adult teeth substitute the deciduous set of teeth. Other vertebrates like toothed fishes are categorised as polyphyodonts, which means that their teeth are continuously substituted during their lifetime. The only mammals which are polyphyodont are kangaroos, elephants, and manatees.

Note: In humans and other vertebrates, teeth play a major role in absorption and digestion. Human beings consume food all through their lives. Thus, to withstand their prolonged use through years of chewing, teeth must be really hard and firmly entrenched. The white, exposed part of the tooth is covered by an enamel layer. This is the body’s hardest substance.
