Tooth Sensitivity

Lady with teeth pain

Tooth sensitivity is also known as dentine hypersensitivity or root sensitivity.

If your teeth feel a short sharp sensation when you take in hot, cold, sweet, very acidic foods and drinks, then you have tooth sensitivity

How Does Sensitivity Develop?

  • The tooth surface is normally protected by a layer of enamel.
  • Under the enamel is a layer of dentine.
  • When the enamel is damaged or eroded, the dentine becomes exposed.
  • Dentine contains millions of tiny tubes that run from the surface of the tooth towards the center of the tooth. Inside these tubes are tiny nerves.
  • When dentine is exposed, the nerves inside the tubes get stimulated by changes in temperature or acidity and respond by feeling sensitive.

Causes of Tooth Sensitivity

There are 2 main causes:

1. Wear of the enamel surface exposing the dentine. This can be due to

  • aggressive brushing
  • teeth grinding
  • acid erosion
  • chipped or fractured tooth
  • tooth decay
2. Gum recession due to

  • aggressive brushing
  • gum diseases
  • aging

How to Manage Sensitivity?

  1. Do not brush the sides of the teeth horizontally and aggressively but gently in a circular motion.
  2. If you drink acidic juices, rinse your mouth immediately after and do not brush for half an hour.
  3. Use specialised toothpastes such as Colgate Sensitive Pro-Relief Extra White or Smart White or Sensodyne.
  4. Consult your dentist for a proper diagnosis and to check for tooth decay.
