Sensitivity Tooth is the condition of a short, sharp pain experienced at the time of consuming hot or cold water / food / beverages. The Outer layer of our tooth is enamel, covering the crown of tooth, the cementum covers the root of the tooth and dentine is the inner layer. Tooth sensitivity is caused when the tooth enamel wears away and the dentine is exposed. There are several ways in which tooth enamel can wear away, thereby exposing the dentine, leaving the tooth prone to sensitivity.
