Your Enamel and Sensitive Teeth
Exposure of your tooth's dentine is the cause
of regular or occasional nerve twinge 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,
resulting in a short, sharp nerve twinge in the tooth."Dentine
hypersensitivity" is the feeling of sensitive sensation when you
stimulate the exposed dentine of the tooth.

This diagram can also help you understand why dentine plays such
an important role in causing sensitivity.
Depending on the product's active
ingredient, relief from the sensation of sensitive teeth could
occur by nerve depolarisation, by occlusion of the exposed tissue
within the dentine tubules or by forming a tooth-like layer over
Nerves within the tooth are triggered by
hot and cold stimuli due to worn enamel or receding gums.
