Our teeth sure do a lot of hard work, chewing our food and making them easy to digest. A lot of people even use their teeth to break extremely hard substances like walnuts, betel nuts, and whatnot! Though it is highly unadvisable to do so, have you ever wondered what makes our tooth so tough? Dr Hafsa Alidrissi, our prosthodontist in Dubai, will guide you through the basics of what a tooth is and how it works.

What Is a Tooth made of? Let our prosthodontist in Dubai guide you

Our teeth are known to be the hardest and the toughest part of our entire body, even more, stronger than our bones. It is the outermost part of our teeth called Enamel that imparts such hardness to our teeth.

Our teeth basically have three layers underneath that tough exterior. If you slice the crown of the tooth, that is the portion visible above the gums it has 3 layers:

  • The outermost Enamel- which is the strongest and hardest part of the body.
  • Underneath the enamel lies a softer layer of dentin which protects the inner soft tissues
  • And the innermost part is called the Pulp which contains all the important blood vessels and nerves which supply the tooth its nutrition.

There is another part of the tooth that is hidden away from us much like the roots of trees. The root/roots of a tooth are present below the gum and embedded in our bone holding the tooth in its place firmly. The root pretty much has similar layers- the innermost pulp, middle dentin, except the outermost layer that is known as cementum (instead of enamel).

Our tooth is living tissue with blood vessels and nerves present inside of it. It is made of various organic and inorganic elements.


What are the different types of teeth?

Humans have 2 sets of teeth in their entire lifetime: 20 milk teeth that erupt during our infancy and fall off by our adolescent years and a set of 32 permanent teeth that erupt in our mouth after the milk teeth have shed. The permanent teeth remain in our mouths for our entire lifetime.

We have various teeth of different shapes, according to their position in the mouth that function differently.

  • Incisors: Total of 8 in number, are present in the front in the mouth, 2 central and 2 lateral incisors in each jaw, used for cutting, tearing, and holding into food.
  • Canines: Total 4 in number present third from the midline, 2 canines present in each jaw are used to tear food.
  • Premolars: Total 8 in number present before molars and after canines, there are 4 premolars in each jaw.
  • Molars: 6 molars in each jaw, are large teeth with multiple roots and used for chewing and grinding food and are present at the end of our jaws.

Fun fact: Wisdom teeth are the 3rd molars present at the farthest end of our mouth and erupt even after 18 years of age. These teeth are generally not of any use for chewing and are vestigial organs like our appendix, hence need to be extracted when giving you trouble!
