The tooth is made of 3 layers, each with unique characteristics and specific function, the enamel, dentin, and pulp. The enamel is the outermost layer of the tooth and gives the tooth it's hard and lustrous appearance. The enamel is thicker on the crown than the root and is the first one to be affected by tooth decay. The only symptom when the enamel is decayed is food lodgment and discoloration.
The dentin is the next layer, which is composed of minute fine tubules leading from the enamel to the living portion of the tooth, which is the pulp. Once decay progresses from the enamel, the dentin is affected, and this leads to sensitivity in the teeth. When the root portion is exposed to the oral environment, because the root is covered by a more delicate substance called cementum, more severe dental sensitivity ensues.
