Sensitive teeth


The symptoms are occasional mild flash of pain or tingly feeling when eating sweet, sour, hot or cold.

What is the cause of sensitive teeth?

On healthy teeth the dentin is protected by gum and enamel. When this protection is lost, microscopic holes in the dentin (tubules), allow heat, cold and other irritants to be transmitted to the tooth nerve triggering pain.

Dentin can be exposed by:

  • Receding gums caused by improper brushing
  • Gum disease or surgery
  • Fractured or chipped teeth
  • Clenching or grinding your teeth
  • Acidic damage from juice or soft drinks

Treatment options

Treatment options, depending on diagnosis:

  • A soft-bristle toothbrush
  • Gentle brushing stroke
  • Toothpaste for sensitive teeth (usually takes several weeks to ease pain)
  • Fluoride rinse or gel
  • Clenching and/or grinding may need a nightguard for use.
  • Reduce consumption of acidic juice and soft drinks. Rinse with water. Click here to read about aciddamage.

Acidic damage of teeth

Tooth enamel kan be desolved by acidic foods and drinks (e.g. orange, lemon, grape fruit, juice, soda, carbonated soft drink – also the “sugar free” type).

You can reduce the risk of acidic damage from fruits/juice/soft drinks on your teeth by:

  • Reducing your consumption to a “normal average” consumption
  • Drink with meals not small sips during the whole day
  • Use a straw
  • Rinse your mouth with water immediately after eating/drinking
  • Never brush your teeth immediately after as the enamel is sensitive to abrasion
  • Use a soft toothbrush in general
