Reasons for tooth sensitivity

Tooth sensitivity occurs when the underlying layer of your teeth, known as dentine, becomes exposed. Dentine contains tiny tubules that lead to the nerves in the center of the tooth, which can cause pain and sensitivity when they are stimulated.

The following are some common reasons for tooth sensitivity:

  1. Brushing too hard: Brushing your teeth too hard or using a hard-bristled toothbrush can wear down the enamel on your teeth, exposing the dentin and causing sensitivity.

  2. Gum recession: When your gums recede, the roots of your teeth become exposed, which can cause sensitivity.

  3. Tooth decay: When tooth decay progresses to the point of exposing the dentin, it can cause sensitivity.

  4. Cracked teeth: A cracked or chipped tooth can expose the dentin and cause sensitivity.

  5. Teeth grinding: Grinding your teeth can wear down the enamel, exposing the dentin and causing sensitivity.

  6. Teeth whitening: Some teeth whitening products can cause temporary sensitivity.

  7. Acidic foods and drinks: Consuming acidic foods and drinks can erode the enamel on your teeth, exposing the dentin and causing sensitivity.

  8. Dental procedures: Some dental procedures, such as fillings, crowns, and root canals, can cause temporary sensitivity.

If you are experiencing tooth sensitivity, it's important to see your dentist to determine the underlying cause and develop an appropriate treatment plan. Your dentist may recommend using desensitizing toothpaste, applying a fluoride gel, or other treatments depending on the severity of your sensitivity.
