This hard surface protects the inner layers of each tooth from the damage of decay or injury. Enamel is the hardest tissue in the whole body. • Dentin. This is the middle layer of the tooth, which is the most similar to bone tissue. Dentin makes up the majority of the tooth structure. It has millions of tiny tubes connecting it to the life-source of the tooth: pulp. • Pulp. The pulp is the living core of each tooth, and the innermost layer. The pulp is made up of blood and nerves. The part of the tooth above the gumline is called the crown. And the part of the tooth below the gumline is called the root, which attaches the tooth to your jawbone.
