What Do The Human Tooth Structure Include

What Is The Human Tooth Structure And What do The Tooth Structure Includes(An Easy Guide)

Have you ever wondered how does human tooth structure looks like,weel donot worry,i have explained in an easy way so that you can understand it well.

The tooth is one of the most unique and complex anatomical and histological structures in the body. The individual tissue composition is restricted to the dental structures of a tooth and is found only within the mouth and 

Each tooth is matched within the same jaw, while the opposing jaw has teeth classified within the same category.

However, they are grouped according to the function but instead by structure. They are seated within the mandible and maxilla’s lower and upper alveolar bones. This unique type of joint is known as gomphosis.

Parts of a tooth are dentin, enameland cementum.

  • Enamel: The most complex bodily tissue covering the surface of the dental crown. It is as hard as a crystal. Enamel is the only nonliving tissue. Because it is not alive, it cannot repair itself from decay or damage.is the most mineralized body part, composed of crystalline calcium phosphate(Hydroxylapatite). It is as hard as crystal.
  • Dentin: The tissue forms the tooth from the dental crown to the tooth root, present inside the enamel and cementum, softer than the enamel. Small tubes filled with tissue fluid, called the dentinal tubules, runs inside the dentin. Dentine forms most of the components of each tooth and extends almost the entire tooth’s length. It is the living tissue. It is softer than enamel, having a structure similar to that of bone.

The  Human Tooth Structure  an essential feature of human anatomy. It’s an intricate system that allows us to eat and chew food.

The enamel is the outer layer of a tooth, which acts as a protective barrier against bacteria and other microorganisms. Because it is sensitive, that is why dentine Protects it.

  • The neck is the area where the crown joins the root. The channel is the dividing region of a tooth at the gum line, where the crown meets the core—the peak of each tooth covered with enamel protecting the central dentine. 
  • The cementum is covering the tooth’s root. The cementum connects the alveolar bone with the tooth by the periodontal ligament. It is softer than enamel but roughly as hard as bone. The connective tissues are attached to the periodontal ligament and bind the tooth’s roots to the gums and jaw (alveolar) bone.
  • Dental pulp: The pulp tissue is called the nerve. Blood vessels, lymph vessels, and nerve fibers are located in the dental pulp, supplying nutrients to the dentin. The pulp area is the innermost portion of the tooth that lies below the dentine and extends from the crown to the apex of the root. The pulp area holds the pulp, which is composed of soft tissue. It contains blood vessels to supply nutrients and blood to the tooth to keep it alive and nerves to enable the tooth to feel the temperature. It also contains small lymphatic vessels carrying white blood cells to the tooth to help fight bacteria.
  • Periodontal ligament: is the tissue that consists mainly of the fibrous connective tissue that connects the alveolar bone to the tooth root. It prevents forces applied to the tooth from being directly imposed on the alveolar bone while chewing food. The periodontal ligament is composed of a bunch of connective tissue fibers. One end of each pile is attached to the cementum covering the tooth’s root. The ligaments on the other end anchor the tooth root to the jaw bone and act as shock absorbers, allowing the tooth to resist biting and chewing forces.

  • Alveolar bone: The bone supporting the tooth; the tooth sets into the jaw bone. When a large portion of the alveolar bone gets destroyed by periodontal disease or other causes, the tooth becomes loose. The jaw bone surrounding and supporting the tooth’s root is the alveolar bone. It contains the tooth sockets within which the tooth roots get embedded.
  • Gingiva is The soft tissue covering the alveolar bone. The gingiva is the pink soft tissue that we call our gums. It protects the jaw (alveolar) bone and roots of the teeth and covers the neck of each tooth.
  • The gingival sulcus is the small space between the tooth and the gums. Healthy gums usually have a depth of 1 to 2 mm in this space. Due to inflammation, When this space deepens, it is called the periodontal pocket or gingival pocket.
  • Root Canal. The root canal is the open space inside the root where the pulp extends from the pulp chamber. Blood vessels and nerves from surrounding tissue enter the pulp through the root canal.
  • Accessory canals are smaller channels that branch from the central root canal to the periodontal ligament through the dentine. They appear near the tooth’s root end. They supply nutrients and nerves to the soft tissue.
  • The tooth crown is the top part exposed and visible above the gum (gingiva). Enamel covers it, which protects the underlying dentine.
  • The tooth’s root descends below the gum line, into the upper or lower jawbones, anchoring the tooth in the mouth. Different types of teeth have a different number of roots and root formations. Typically incisors, canines, and premolars will have one core, whereas molars will have two or three.
  • The apical foramen is the tiny slit at the tip of each root. It is what blood vessels and nerves from surrounding tissue pass through to enter the tooth.

How many roots does each tooth have?

The number of roots for each type of tooth varies. Typically incisors, canines, and premolars will have one core, whereas molars will have two or three.
