The Anatomy of Your Teeth

Teeth are complex structures that are vital to our ability to eat, speak, and smile. They are composed of several different layers and structures, each of which serves a specific function. Here's a closer look at the anatomy of your teeth:


The enamel is the outer layer of the tooth, and it is the hardest material in the human body. Its main function is to protect the tooth from wear and tear caused by biting and chewing.


Beneath the enamel is the dentin, which is softer and more porous than enamel. Dentin makes up the bulk of the tooth and gives it its shape and color.


The pulp is at the center of the tooth, which contains nerves, blood vessels, and connective tissue. The pulp is responsible for nourishing the tooth and providing sensation to the tooth.


The cementum is a layer of hard, mineralized tissue covering the tooth's root. It helps anchor the tooth to the jawbone and protects the sensitive root structure.

Periodontal Ligament

The periodontal ligament is a thin tissue layer connecting the tooth to the surrounding bone. It helps to absorb shock and keep the tooth securely in place.

Root Canal

The root canal is a hollow space within the tooth that contains the pulp. When the pulp becomes infected or inflamed, a root canal procedure may be necessary to remove the damaged tissue and save the tooth.


The crown is the tooth's visible part above the gum line. It is composed of enamel and dentin and is responsible for biting, chewing, and grinding food.

The Bottom Line

Understanding the anatomy of your teeth can help you better care for your oral health. By brushing and flossing regularly, eating a healthy diet, and seeing your dentist regularly, you can help keep your teeth healthy and strong for years to come. A children's dentist, also known as a pediatric dentist, can help new parents care for their children's teeth. It is important to start early to preserve those pearly whites for a long time to come.
