Our teeth are fascinating structures that play a crucial role in our overall health and wellbeing. They help us bite and chew our food, speak clearly, and give us a beautiful smile. But have you ever wondered about the structure of your teeth? In this article, we'll take a closer look at the anatomy of our teeth, from the outside to the inside.

The Enamel


The enamel is the outermost layer of our teeth and is the hardest substance in the human body. It is made up of tightly packed mineral crystals and protects the teeth from daily wear and tear, as well as from bacteria and other harmful substances. However, despite its strength, the enamel can be damaged by acid erosion and physical trauma.



Beneath the enamel lies the dentin, a hard tissue that makes up the bulk of our teeth. Dentin is less mineralized than enamel but still provides support and protection to the tooth. When the enamel is damaged, the dentin becomes exposed, making the tooth more sensitive to temperature changes and sweet or acidic foods.

The Pulp

Our teeth's pulp, which is located on the inside, is made up of connective tissue, blood vessels, and nerves. It plays a crucial role in tooth development, but once our teeth are fully formed, the pulp's main function is to sense hot and cold temperatures and provide nourishment to the tooth.

The Cementum

The cementum is a layer of hard tissue that covers the roots of our teeth. It provides attachment for the periodontal ligament, which helps hold the tooth in place in the jawbone.

The Periodontal Ligament

The periodontal ligament is a fibrous tissue that connects the cementum to the jawbone. It acts like a shock absorber, allowing the tooth to withstand the forces of biting and chewing.

The Alveolar Bone


The alveolar bone is the bone that surrounds and supports our teeth. It is essential for maintaining healthy teeth and gums, as well as for preventing tooth loss. The alveolar bone can be damaged by periodontal disease, a common condition that affects the gums and bone that support the teeth.

The Tooth Crown

The area of the tooth that is visible above the gum line is known as the tooth crown. It is made up of enamel and dentin and comes in a variety of shapes and sizes, depending on its position in the mouth and its function.

The Tooth Root

The tooth root is the part of the tooth that is embedded in the jawbone. It is covered by cementum and anchors the tooth in place, allowing it to withstand the forces of biting and chewing.

Types of Teeth


1. Incisors

These are the front teeth in our mouth and are used for biting and cutting food.


These are the pointed teeth next to the incisors and are used for tearing and ripping food.


These are the teeth located between the canines and molars and are used for crushing and grinding food.


These are the back teeth in our mouth and are used for grinding and crushing food.


Maintaining good oral health requires knowledge of the structure of our teeth. By taking care of our teeth and gums, we can prevent tooth decay, gum disease, and other oral health problems. Regular dental checkups, brushing and flossing daily, and eating a healthy diet are all crucial steps in maintaining healthy teeth and gums.
