Let's solve the
Tooth Anatomy Quiz by identifying each labeled part of the tooth in the diagram.
---
Step-by-Step Identification:
Here is a breakdown of the numbered parts based on standard dental anatomy:
1.
Enamel – The hard, outermost layer of the tooth that covers the crown. It’s the white, shiny part visible when you look at your teeth.
2.
Dentin – The thick layer beneath the enamel and cementum. It is less hard than enamel but still provides structural support.
3.
Pulp cavity – The central chamber inside the tooth that contains nerves and blood vessels (the pulp).
4.
Pulp – Soft tissue inside the pulp cavity containing nerves, blood vessels, and connective tissue. It gives the tooth sensation.
5.
Bone (Alveolar bone) – The jawbone that surrounds and supports the tooth root.
6.
Crown – The visible part of the tooth above the gum line.
7.
Gingiva (Gums) – The soft tissue that surrounds and protects the base of the tooth.
8.
Cementum – A thin layer covering the root of the tooth; helps anchor it to the periodontal ligament.
9.
Periodontal ligament – Connective tissue that attaches the tooth to the alveolar bone.
10.
Root canal – The narrow channel inside the root of the tooth that contains nerves and blood vessels extending from the pulp.
11.
Root – The part of the tooth below the gum line that anchors the tooth into the jawbone.
12.
Nerve and blood vessels – The structures running through the root canal, supplying the tooth with nutrients and sensation.

🔍 Explanation Summary:
This diagram illustrates a
cross-section of a human tooth, showing both the
crown (above the gum) and the
root (below the gum). Key features include:
- The
enamel is the hardest substance in the body, protecting the tooth.
- The
dentin makes up most of the tooth and is sensitive to pressure or decay.
- The
pulp contains nerves and blood vessels — this is why toothaches occur when the pulp is infected.
- The
periodontal ligament acts like a shock absorber, allowing the tooth to move slightly during chewing.
- The
gingiva (gums) protect the roots and prevent infection.
Understanding these parts is essential for oral health and dental care.
