What causes tooth sensitivity?

Tooth sensitivity can occur while brushing your teeth or when a cold or hot, sweet or sour stimuli creates an intensely painful reaction in the mouth. It usually occurs when the outer protective layers of enamel or cementum are removed, exposing the dentin due to receded gums or periodontal disease.

Causes of sensitive teeth

  • Damaged fillings
  • Fractured tooth or worn enamel because of teeth grinding
  • Teeth grinding or clenching
  • Aggressive tooth brushing or incorrect way of brushing teeth
  • Plaque build-up on the root surfaces
  • Exposed root areas due to receding gums or periodontal disease
  • Enamel corrosion caused by chemical agents or acidic diet
  • Tooth decay
  • Frenum pull and poor oral hygiene

How to prevent sensitive teeth

  • Use a soft-bristled toothbrush.
  • Go easy on highly acidic foods (such as citrus), as they can erode tooth enamel and lead to dentin exposure.
  • Use a mouth guard if you grind or scrunch your teeth at night.
  • Regular visits to the dentist for cleaning and fluoride treatments can prevent damage to the dentin's protective layer.
  • Brushing properly at least twice a day and flossing daily.
  • Use low abrasivity toothpaste. Whitening and anti-tartar toothpastes are usual causes of tooth sensitivity.
  • Maintain good oral hygiene. Keep your gums healthy to prevent gums recession.


Sensitive teeth can be solved by using a desensitizing toothpaste. If the toothpaste doesn't work your dentist can apply a fluoride gel or special desensitizing agents to the affected tooth. If the problem is continuing, a filling, cap, insert or bonding may be required to fix tooth decay or correct some other problem that may be causing the sensitivity.
