Tooth Sensitivity

Tooth sensitivity is a sharp pain or discomfort that occurs when teeth are exposed to stimuli such as cold, heat, acidic foods, or sweets. It usually affects the outer layer of the tooth (enamel) or the dentin, which protects the inner nerves.

Most common causes

• Enamel wear: caused by brushing too hard or using abrasive toothpaste.

• Gum recession: exposes the tooth root.

• Tooth decay or wear from bruxism (teeth grinding).

• Recent dental treatments: such as whitening or deep cleaning.

• Acidic foods and drinks: citrus fruits, soft drinks, vinegar.

  Symptoms

  • Brief, sharp pain when eating or drinking cold, hot, sweet, or acidic foods.

  • Discomfort when brushing or flossing.

  • Sometimes it is felt in a single tooth or in several teeth.
