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