What Are Your Teeth Actually Made Of?
Let’s take things step by step here. First and foremost, your teeth have several layers to them; each with a purpose. The hard outer shell of your teeth is called enamel. The purpose of enamel is to protect the inner layers of your teeth. So how strong is enamel, exactly? You might be surprised by this, but enamel is actually the hardest substance in your body! It’s even harder than your bones. So what’s underneath that hard, shiny armor? The next layer after the enamel is called dentin. Dentin protects the very inner layer of your teeth, known as pulp. It’s also a little less stronger than enamel but is just about as hard as your bones. So what’s this “pulp” we speak of and why does it need to be protected? Pulp contains the nerve endings of your teeth and is where the blood supply can be found that connects to each tooth to provide the nutrients needed for each. Pretty neat, huh? But we’re not done yet! What about the roots of your teeth? These substances, called cementum, anchor each tooth to the jawbone.
