Tooth wall anatomy

What is the anatomy of the tooth structure?
The tooth has two anatomical parts, the crown and the root.
The crown is the top part that is exposed and visible above the gum (gingiva).
It is covered with enamel, which protects the underlying dentine.
The root of a tooth descends below the gum line anchoring the tooth in the mouth..
What is the surface anatomy of the tooth?
Lingual – The surface that faces the tongue.
Mesial – The surface that is closest to the midline of the face.
Occlusal– The chewing surface of posterior teeth.
Proximal – Tooth surfaces that are next to each other (i.e., distal of lateral incisor and mesial of canine)..
What is the wall of a tooth?
PULPAL WALL-A pulpal wall is an internal wall that is perpendicular to the long axis of the tooth and occlusal of the pulp..
Our teeth are made of a hard, bone-like substance.
They are held by small sockets in our upper and lower jawbones called dental alveoli.
Strong fibers anchor them in place.
The upper and lower sets of teeth form two arches.
Pulp: The softer, living inner structure of teeth.
Blood vessels and nerves run through the pulp of the teeth.
Cementum: A layer of connective tissue that binds the roots of the teeth firmly to the gums and jawbone.
Periodontal ligament: Tissue that helps hold the teeth tightly against the jaw.

Which part of a tooth sits between a crown and a root?

The neck, also called the dental cervix, sits between the crown and root

It forms the line where the cementum (that covers the root) meets the enamel

Gums

Gums, also called gingiva, are the fleshy, pink connective tissue that’s attached to the neck of the tooth and the cementum

Pulp

Pulp is the innermost portion of the tooth
