Tooth Sensitivity


Tooth Sensitivity:  

More than 40% of adults experience tooth sensitivity, also known as Dentin Hypersensitivity. Most people experience tooth sensitivity as a short, sharp pain originating from a tooth or teeth in their mouth. It affects either the tooth or the exposed root surfaces. It is also known to occur more frequently in women than in men.

Why does it occur?

Tooth sensitivity occurs when the dentin - which is protected by the tooth enamel - loses its natural protection and is exposed.

The dentin consists of thousands of microscopic tubes, called dentinal tubules, which connect the external part of the tooth to the nerve endings. When a tooth loses its protection due to gum recession and/or tooth enamel wear, these tubules are exposed to the outside atmosphere, thus allowing external stimuli to reach the nerve endings and cause pain.


There are numerous circumstances which can cause the dentinal tubules to become exposed, thus triggering Tooth Sensitivity. These tend to be mostly related to patients daily oral hygiene habits and lifestyle choices:

  • Using abrasive toothpaste or increasing the frequency of brushing may cause abrasion to the enamel and/or cementum, exposing the dentin.

  • Consuming acidic food and drinks (citric juices, carbonated soft drinks, etc.) cause tooth decalcification or erosion of enamel leading to sensitivity.

  • Excessive chewing force, bruxism or poor habits can cause wear (attrition, abfraction) and exposure of the dentinal tubules.

  • Periodontal treatment, especially surgery, can remove some of the gum, leading to gingival recession which in turn expose the dentin.

  • Stomach disorders (ulcers, hernias, etc.), psychological disorders (bulimia, anorexia nerviosa) or job-related (wine tasters, bakers, etc) activities can cause tooth sensitivity

  • Gingival recession caused by dental-treatments, including professional cleaning, basic periodontal treatment or orthodontics can also lead to dentinal sensitivity.
