Living with tooth sensitivity

Tooth sensitivity facts

Tooth sensitivity — also known as dentine hypersensitivity — affects the tooth via exposed root surfaces or surfaces where enamel has been lost.

This occurs when the enamel that protects the teeth wears away, or when gum recession occurs, exposing the underlying surface, the dentine, thus, reducing the protection the enamel and gums provide to the tooth and root.

Signs & symptoms

If hot, cold, sweet or very acidic foods and drinks, breathing in cold air, or touching the affected surface makes your teeth or a tooth sensitive, then you may have dentine hypersensitivity. Tooth sensitivity can come and go over time.


There are many causes of tooth sensitivity, including:

  • Worn tooth enamel from using a hard toothbrush or brushing too aggressively

  • Tooth erosion due to highly acidic foods and beverages

  • Tooth erosion due to bulimia or gastro-esophageal reflux disease

  • Gum recession that leaves your root surface exposed

I love spicy food, the type of food you have to avoid with sensitive teeth. Now I want to order the chilli crab, the type you have to crack with your mouth!
