Understanding the anatomy of your teeth can help you have a better understanding of your oral health. Just like your body, there are many layers that make up your teeth’s composition. Keep reading to learn about the anatomy of your teeth!

How Many Teeth Do Adults Have?

On average, adults have 32 teeth. Of the 32, adults have 8 incisors, the 4 top and bottom teeth at the front of the smile. Adults also have 4 canines which are the teeth that appear to be pointier than the others, 8 premolars, and 12 molars (including 4 wisdom teeth).

Layers of Our Teeth

On the outside of the tooth, there are three sections: the crown, which is the top of the tooth, the neck, which is the middle of the tooth, and the roots which are what hold the tooth in place. On the inside of the tooth, there are multiple layers:

  • Enamel: Enamel is the outer layer of the tooth. It is made up of minerals and is extremely tough and durable. Enamel is the protective shell of the tooth that helps protect it from damage.
  • Dentin: Dentin is located directly beneath the enamel. It is made up of soft minerals, tubules, and living tissue. It helps support the tooth’s structure and communicate with the tooth’s nerves.
  • Pulp Cavity: The pulp cavity is in the center of the tooth. The pulp cavity contains pulp, a combination of blood vessels and nerves.
  • Cementum: Cementum, also known as cement, is a bone-like layer that protects tooth roots. It also helps maintain a good bite distribution.
