Crown. Root. Enamel. These are all parts of your teeth that you’ve probably heard of before. But what are they made of? What do they do? And what are the other parts of your teeth?

Enamel

Enamel is actually the hardest substance in your body. It is a calcified barrier that covers the outside of your teeth.

Crown

The crown of the tooth is simply the part that you can see.

Neck

This is where the tooth crown and root meet.

Gums

While not technically part of the tooth, gums (or gingiva) are important because they support teeth. This soft tissue also protects teeth roots and teeth that haven’t erupted yet.

Root

This is the part of the tooth that you can’t see because it is in the bone socket.

Dentin

This hard tissue makes up the majority of your tooth. It contains tubes which are sensitive to heat, cold, or acids if too much tooth enamel is lost.

Pulp

This is the softest tissue of the tooth, containing blood vessels and nerves that supply it. Pulp extends from the center of the tooth (pulp chamber) to the root.

Root Canal

This is the part of the tooth root through which the pulp extends.

Cementum

This hard tissue covers the tooth root and connects it to the periodontal ligament.

Periodontal Ligament

The periodontal ligament holds the tooth root to its socket. This fibrous tissue also acts as a shock absorber.
