When Tooth Sensitivity (Dentin Hypersensitivity)Happen?

Tooth sensitivity usually causes When the second layer of tooth structure Dentin(See Pic.1) is exposed, then it causes tooth sensitivity. In Dentin one of the important structures is Dentinal Tubule. Dentinal Tubule(See Pic.2) is a tube or canal-like structure which present inner to outer side direction of the tooth, when it exposed then impulse from outside, it irritates the inner structure of tooth pulp & causes tooth sensitivity. If it is not treated on time then later can cause dental pain & tooth loss.

Know How Sensitivity toothpaste Stops the Tooth Sensitivity:

Generally when Dentinal Tubule is exposed then tooth sensitive to cold is noticed, the impulse from outside, it irritates the inner structure of tooth pulp & causes tooth sensitivity. Commonly Potassium nitrate or strontium chloride used in to stop sensitivity.  It is used to block the Dentinal tubule (See Pic.2) & temporary reliefs from tooth sensitivity.

How Dentin or Dentinal Tubule is exposed:

  • Fractured teeth

  • Due to some poorly restored metal filling.
  • Exposed tooth root etc.

NOTE: Tooth gum disease is one of the common dental problems in our society. Tooth gum disease causes due to lack of oral hygiene maintenance. What we eat, that food particles accumulate on & in between the tooth which causes irritation to the tooth gum & gum diseases. To clean these food particles daily proper tooth brushing & every 6-th month(at least yearly once) Scaling treatment is strongly recommended.

  • Take balanced diet & vegetables- Proper nutrition is important.
  • Topical Fluoride can be used, ask your Dentist-use as your Dentist advice.
  • Avoid Tobacco, Gutka, Betel nuts & Alcohol

Treatment of Tooth sensitive to cold:

Tooth Sensitivity toothpaste closes the opening of Dentinal tubules, so impulse or irritation can’t go inside & temporarily stop the tooth Sensitivity, but permanently it’s not cured. So, as a Dentist I will suggest you do the proper treatment, solve the cause of sensitivity & that will give you the permanent solution. If you have Caries, fracture, compromised filling or tooth attrition, erosion then treatment option can be new tooth filling Or Root canal treatment- treatment will be depending upon tooth condition. For gum problem, periodontal treatment is indicated. If you are getting tooth sensitivity then immediately visit a Dentist.


Tooth sensitive to cold is a symptom of a disease. Don’t neglect this problem. Don’t take treatment on your own, take specialist advice. If you take the correct treatment at the correct time then easily you can protect your tooth, if you getting tooth sensitivity immediately take specialist advice. So to get permanent relief & do the proper treatment, know the cause of sensitivity, treat the disease & automatically you will get relief from symptoms of tooth sensitivity.
