A Tooth’s Anatomy – Every Structure Explained Easy

Our teeth form an essential part of our body. However, only after contracting an oral disease, we realize the true importance of the 32 sets of whites. A tooth has a marvelous structure. Hence, general knowledge of tooth’s anatomy will help us understand and appreciate this unique part of our body.

If you drill into a tooth from top to bottom, you will encounter these structures as you go down.

  • Enamel.
  • Dentine.
  • Pulp cavity.
  • Root canal.
  • Cement.
  • Bone.

Enamel:

It is a hard mineralized tissue. Mostly made up of non-organic compounds such as calcium, phosphate, and traces of magnesium, lead, and fluoride. Furthermore, minute spaces also called pores exist in between the structure. These pores contribute to the permeability of enamel, allowing nutrients to diffuse through the enamel. During cavities, the pores widen, which weakens the structure of enamel.

Dentine:

Dentine is another mineralized tissue, but less rigid compared to enamel. It comprises about 70% inorganic material, and water and organic compounds makes the rest of it. It acts as a mechanical barrier. Consequently, it protects the enamel from fracture, often caused by intense pressure. Furthermore, it also protects the pulp cavity from bacteria and toxins.

Pulp Cavity:

Pulp cavity is the cells and blood vessels rich zone of the tooth. The pulp contains two types of cells in high concentration that produce different types of collagens and fibers. These fibers and collagens contribute to the structural stability and elasticity of the pulp. Also, the pulp contains an extensive network of blood supply and neurons. Hence, it provides nutrients and defense for the growth and repair of dentine and cement.

Root Canal:

The root anchors the teeth, and it extends below the gum-line. Primarily made up of pulp tissue. Different types of teeth contain a different number of roots. For example, incisors and canines have one root while molars have two to three roots.

Similarly, a dental procedure “Root Canal” is also named after this part of the tooth’s anatomy. In this procedure, the root canal is cleared of the infection and the repaired tooth is planted back again.

Cement:

A bone-like material, but softer than enamel and dentine. It is a yellowish cellular region with connective fibers. The connective fibers connect the tooth’s root to the gum line, further anchoring the tooth firmly in its place.

Unlike enamel, this is a regenerative structure of a tooth. Hence, this network keeps forming throughout human life. Particularly during stress and wear out of the crown (the top layer of the tooth, like enamel and dentine), the formation of cement increases to maintain a uniform bite level.

Bone:

Also known as the alveolar bone. This bone is an extension on the jaw bone with sockets to accommodate the tooth’s root.

Conclusion:

The strength and durability of our teeth are undeniable. However, this does not mean our tooth is prone to disease and bacterial attacks. Thus, without proper oral hygiene, even the sturdiest tooth gets weak. Hence, to save yourself from trouble, it is best to contact a dentist regularly.
