It’s back-to-school season! While kids are getting ready with fresh notebooks and new routines, it’s also the perfect time to brush up on the basics of oral health—starting with what’s inside your smile. Understanding the different parts of your teeth can help you take better care of them. So let’s go back to basics with a refresher on the anatomy of your teeth!
What Are Teeth Made Of?
Your teeth are small, but they’re made of several layers that each have an important job. Here’s an explanation of each layer and how they work together.
Enamel
This is the hard, shiny outer layer of your tooth—and it’s the strongest substance in your body! Enamel protects your teeth from chewing, biting, and bacteria. But it can wear down over time, especially if you eat a lot of sugar or skip brushing.
Dentin
Right underneath the enamel is dentin. It’s not as hard, and it’s a little yellowish in color. If enamel wears away, dentin can become exposed—and that can make your teeth feel sensitive.
Pulp
The pulp is in the center of the tooth. It’s soft and full of nerves and blood vessels. The pulp helps your tooth grow and stay healthy. If a tooth gets a deep cavity or crack, the pulp can get infected and may need treatment.
Cementum
This covers the root of the tooth and helps hold it in place. It’s not something you can see, but it works hard below the surface!
Periodontal Ligament
This is the stretchy tissue that connects your teeth to your jawbone. It acts like a cushion every time you bite or chew.
Why This Matters
Just like knowing how your heart or lungs work, understanding your teeth helps you keep them strong. When you brush and floss every day, you’re protecting all those layers—especially your enamel and gums. And remember: your permanent teeth need to last your whole life. The better you care for them now, the happier your smile will be in the future!
