Top 5 causes of tooth sensitivity 

Why are my teeth sensitive?

Have you ever felt pain after a bite of ice cream or hot soup? If so, it could be a sign of sensitive teeth. Tooth sensitivity causes pain or discomfort in the teeth when you eat hot or cold food. It may be temporary or a chronic problem. Most cases of sensitive teeth can be treated with a change in your oral hygiene regimen.

The most common triggers of sensitive teeth include:

  • Hot foods and beverages
  • Cold foods and beverages
  • Sweet foods and beverages
  • Brushing or flossing teeth
  • Alcohol-based mouth rinses
  • Sweet foods and beverages
  • Acidic foods and beverages

Below your enamel is a part of the tooth called dentin. This is soft tissue full of nerves, this can be sensitive and painful. Over the years our habits and behaviors can lead to wear down your enamel and also lead to gum recession and increases tooth sensitivity.

Some of the most common reasons for tooth sensitivity are:

  • Brushing your teeth too aggressively
  • Exposure to acidic food and drinks such as citrus, coffee, and soda
  • Tooth decay
  • Broken teeth that expose the dentin
  • Broken or leaking fillings
  • Grinding your teeth

Talk with your dentist about which of these behaviors might be causing your problem. Tooth sensitivity can also be caused due to infection or cavity that needs treatment or due to thinning enamel. It’s always best to consult your dentist to know more about the reasons and treatments for teeth sensitivity.

Treating sensitive teeth

  • Brush teeth gently
  • Use soft-bristle brush
  • Wear a nightguard

Gum recession

Gum recession can leave your tooth exposed and unprotected causing sensitivity. Tooth decay, broken teeth, chipped teeth, and worn-down fillings or crowns can cause sensitivity. We recommend that you get your teeth checked by a dentist to examine the root cause of your problem. A dentist can check the health of your teeth and check for problems like cavities, loose fillings, or recessed gums that could be causing the sensitivity.


You can find a variety of toothpaste for sensitive teeth at the drugstore. This toothpaste decreases the sensitivity of the nerves in your dentin.  In addition, a fluoride gel applied to each tooth by the dentist can strengthen your enamel and protect sensitivity from increasing.

If you are suffering from sensitive teeth, please get in touch with us now. Our dentist can recommend a suitable treatment for you.
