Why do I have sensitive teeth?


We have all experienced tooth sensitivity when we bite into an ice cream or have a steaming hot cup of tea, but what causes it and how can we prevent it?


The primary culprit behind tooth sensitivity is the erosion of tooth enamel. Enamel, the hardest substance in the human body, serves as the protective layer for the softer, more sensitive tissue beneath it. In an unfortunate turn of events, your enamel can wear down, exposing the dentine layer and its tubules that lead directly to the tooth’s nerve centre. No wonder you’re experiencing such a shocking sensation!


  1. Overzealous brushing causes gum recession which then causes sensitivity. This is because the root is much more sensitive than the enamel of the crown. Electric toothbrushes are helpful in preventing gum recession

  2. Acidic foods and beverages: Citrus fruits, sodas, and pickles can erode your enamel over time.

  3. Tooth grinding: Grinding your teeth at night can result in chipped enamel and cracked teeth.

  4. Tooth-whitening products:  Overuse of tooth-whitening products can cause tooth sensitivity.

  5. Receding gums: Gum recession can expose the sensitive root surfaces of your teeth, leading to increased sensitivity.

  6. Tooth decay


Here are some helpful tips to alleviate tooth sensitivity and protect your precious enamel:

  • Use an electric toothbrush with a pressure sensor which will indicate if you are pressing too hard.

  • Opt for a fluoride toothpaste designed for sensitive teeth.

  • Wear a night guard if you grind your teeth.

  • Limit your consumption of acidic foods and beverages.

  • Visit your dentist at least every 6 months to monitor and address any concerns.

  • Cut out sugary foods and drinks
