A normal healthy tooth is hard as nails, well not literally, but the hard protective cover (enamel) is one of the hardest substances in the body and provides good protection against sensitivity. Its job is to shield the soft inner of the tooth that contains the nerves and blood supply. If your tooth enamel thins, areas beneath the enamel called dentine can become


exposed. Dentine contains thousands of microspocic tubules, when uncovered tubules are exposed to hot, cold acid or sugars, the flow of fluid inside the tubules increases and is transmitted to the nerve endings located in the pulp. This results in a sudden, sharp pain.
