Tooth sensitivity occurs when the layer of a tooth underneath the enamel (called dentin) or the layer covering the root (called cementum) is exposed along the gum line due to receding gums. Dentin is the most sensitive layer of the tooth. Thousands of microscopic channels run through the dentine towards the center of the tooth. Once the dentine is exposed to external triggers such as cold drinks can stimulate the nerves inside the tooth, causing the typical short sharp sensation of tooth sensitivity.
