What Makes Up a Tooth? 

June 15, 2022

Dental professionals who specialize in endodontics in 23111 go above and beyond to save one of the most complex anatomical structures in the body – the tooth. Each tooth plays a significant role in digesting food, enunciating words, maintaining jawbone density, and preserving the facial shape. If you’re looking to learn more about what makes up the tooth, we’re here to give you a closer look at its anatomy. 

What Are the Basic Parts of a Tooth?

Crown 

Since the crown comprises everything visible above the gum line, people often use “tooth” and “crown” interchangeably. However, it’s important to note that the crown is only around 1/3 of the whole tooth. While all types of teeth, such as the molars, canines, and incisors, have a unique purpose, the shape of each crown determines a specific tooth’s function. 

Enamel 

The enamel is the tough outer shell of the tooth that primarily exists to protect the tooth’s internal structures from damage. Since the enamel consists of calcium phosphate minerals, it’s the hardest substance in the body. However, an unbalanced diet, bad lifestyle habits, and poor oral hygiene can compromise the enamel’s integrity and lead to tooth decay and cavities. 

Dentin 

The dentin refers to the yellowish material that lies underneath the enamel. Although this dental layer is stronger than bone, it’s softer than the enamel. Since the dentin is composed of microscopic tubules, the tooth becomes highly sensitive to chewing and hot and cold sensations when the dentin is exposed.  

Cementum 

This layer of tissue is the surface layer of the tooth’s roots. It connects the roots to the gums and jawbone and helps repair and regenerate the teeth. Damage to the cementum causes the tooth to become more mobile. 

Root 

The root that makes up about 2/3 of the tooth is embedded in the gums and jawbone. Moreover, it surrounds the dental pulp at the center of the tooth. 

Pulp

The pulp contains the tooth’s blood vessels, connective tissue, and nerves. It helps keep the tooth alive by supplying it with blood.
