What Are Teeth Made Out Of?

Understanding what your teeth are made of can help you understand how external factors affect your dental health. You brush, you floss, then smile in the mirror to inspect your handiwork and ensure there’s no lingering spinach stuck anywhere. But as you’re looking at them, are you thinking “oh, my enamel looks rough today”? No, probably not.

Layers of your Teeth

You have four “types” of teeth. They each serve different functions based on their shape, but they’re all comprised of the same general layers of tissue.
  • Incisors
  • Canines
  • Premolars
  • Molars
You also may have a fifth type of tooth, or Third Molar. These are also more commonly known as wisdom teeth! About Wisdom Teeth

What are Teeth Made Out of? – Tissue Layers

Your teeth have both hard and soft tissue. The four layers of your teeth each have a different purpose for keeping your smile healthy.
  • Enamel
  • Dentin
  • Cementum
  • Pulp
The enamel is the outermost layer of your tooth, which is a strong but thin mineral layer that protects your teeth from decay. The second layer of the tooth, called dentin, is a calcified hard tissue. This is softer than enamel but still harder than bone, which allows it to support the overall structure of your tooth. Cementum is the third layer, which covers the root of the tooth to provide stability. The innermost layer of the tooth is called pulp. This soft tissue layer provides a medium for blood vessels and nerves to meet from the roots. Will you be able to identify the different types and tissues of your teeth at your next dental visit? Ask Dr. McNeely for some photos and x-rays to look at so you can practice!
