Tooth Sensitivity

Tooth Sensivity

Tooth sensitivity, also known as dentin hypersensitivity, is a common dental condition characterized by discomfort or pain when teeth are exposed to certain stimuli. This sensitivity occurs when the underlying dentin, a porous tissue beneath the enamel, becomes exposed due to enamel erosion, gum recession, or other dental conditions.

Symptoms of tooth sensitivity include sharp, sudden pain or discomfort when consuming hot, cold, sweet, or acidic foods and beverages. Individuals may experience a temporary jolt of pain that subsides once the stimulus is removed. This sensitivity can also be triggered by cold air or while brushing and flossing.

Various factors contribute to the development of tooth sensitivity. Enamel erosion caused by aggressive brushing, acidic foods, or drinks can lead to dentin exposure. Gum recession, often due to gum disease or improper brushing, exposes tooth roots, contributing to sensitivity. 

Dental conditions such as cavities, cracked teeth, or worn-down fillings can also cause discomfort.


  • Patient History: Inquire about specific triggers and frequency of sensitivity.
  • Visual Examination: Dentists look for signs of enamel erosion, gum recession, or tooth wear.
  • Cold Air or Water Test: A controlled application of cold air or water to identify sensitive areas.


  • Desensitizing Toothpaste: Contains compounds to reduce tooth sensitivity over time.
  • Fluoride Treatments: Strengthen enamel and reduce sensitivity.
  • Dental Bonding: Application of resin to cover exposed tooth surfaces.
  • Gum Grafting: For severe gum recession exposing sensitive roots.

When tooth sensitivity is a result of more severe conditions like gum disease or tooth decay, treating these underlying issues becomes paramount in alleviating sensitivity symptoms. Regular dental check-ups enable dentists to identify and address potential causes of sensitivity before they progress.

Educating individuals on proper oral hygiene practices, avoiding acidic or sugary foods, and using fluoride-based products helps manage tooth sensitivity. Understanding the factors contributing to sensitivity empowers individuals to make informed choices, maintain oral health, and minimize discomfort associated with sensitive teeth.
