On this page, you will learn about why teeth are important, the parts of a tooth and their functions, and basic instructions for caring for your teeth. Let’s get started!

Why Do We Need Teeth?

Of course we need teeth for chewing, but here are the other reasons we need our teeth:

Parts of a Tooth and Their Functions

Teeth are made up of many different sections and tissues. We will list them for you here.

Crown
This is the top part of the tooth. The shape of the crown enables different functions.
Root
The anchor that keeps a tooth in place.
Nerves and blood vessels
Nerves in the teeth are sensory, they carry information on hot or cold.
Gums
Keep your teeth in place and provide a barrier against infection.
Enamel
The enamel is the outer layer of the tooth. It is the hardest and most mineralized tissue for humans. It protects your teeth from damage.
Dentin
This is the layer underneath the tooth enamel surface. It absorbs pressure from eating and transfers impulses from the enamel to the pulp.
Pulp
Soft, living tissue that consists of nerve tissue and blood vessels.
