Your Enamel and Sensitive Teeth
Exposure of your tooth's dentine is the cause of regular or occasional nerve tooth ache and sensitivity, which can be quite annoying.
Dentine lies just below the enamel. Thousands of microscopic tubes run through the dentine. Once dentine is exposed, the nerves within these tubules may become susceptible to triggers such as cold food or drinks resulting in a short, sharp nerve sting in the tooth.
"Dentine hypersensitivity" is the feeling of discomfort when you stimulate the exposed dentine of the tooth and your teeth hurt from exposure to that stimuli.
