Understanding Your Teeth

Your Enamel and Sensitive Teeth

Exposure of your tooth's dentine is the cause of regular or occasional nerve tooth pain and sensitivity, which can be quite annoying.

Dentine lies just below the enamel. Thousands of microscopic tubes or tubules 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 pain in the tooth.

"Dentine hypersensitivity" is the feeling of pain when you stimulate the exposed dentine of the tooth and your teeth hurt from exposure to that stimuli.
