Tooth sensitivity is a painful condition affecting 1 in 7 people, commonly aged 20-40. This condition more often affects women than men. The pain is transitory and usually the result of the tooth nerve cells becoming exposed to chemical or thermal stimuli through open tubules that run from the surface of the tooth through to the dentine. There can be several causes of tooth sensitivity. These include:
-Dental Erosion: Or loss of tooth enamel can cause sensitivity. Enamel is the hard outer coating of a tooth that protects the sensitive dentine underneath. If eroded, the exposed dentine can lead to pain and sensitivity which worsens with extreme temperatures.
-Diet: Frequent consumption of high sugar or high acidic foods and drinks can cause enamel wear and lead to sensitivity.
-Post Tooth Whitening Procedures: Temporary pain can be experienced after tooth whitening.
Degrees of sensitivity may vary, with some individuals able to put up with it while for others the problem has a deep impact on their lives, effecting oral hygiene regime and diet. Most solutions and treatments work by blocking these tubules to prevent the stimuli penetrating the surface of the tooth.
