Biology of the tooth and knowing a bad tooth


From ancient times teeth have been very special having stories from fairy tales to scientific studies. It would be unwise to study about bad teeth before having prior knowledge about teeth and its features.

What is a tooth?

A tooth is a firm structure found in the jaws of a person used when eating food. It is a misconception to think a tooth has no cells, but it is rather made up of different tissues that have various levels of hardness.
What are the features of a tooth?

A tooth has three parts that are unique from each other and serve different purposes. The following are part of a tooth:

  • The crown
  • The crown is the part of a tooth in someone’s mouth that you can see. Food is chewed upon its surface. It is made up of a hard substance called enamel.

  • The neck
  • The neck is the part of the tooth that lies in between the crown and the root of a teeth.

  • The root
  • The source/root of a tooth is the part of the tooth embedded in the gums of the mouth.

Different teeth in a person serve different purposes, and they all serve particular purposes in the mouth. The four types of teeth in a person’s mouth are:

  • Incisors
  • These are the frontal teeth in a person’s mouth, and they are chisel shaped to enable you to bite food.

  • Canines
  • Canines are pointed and are used to tear food like meat.

  • Molars and premolars
  • These type of teeth have ridged like surfaces that are used to grind food.
