The Effect of Cold Weather on Sensitive Teeth

Have you ever noticed that as the temperature outside starts to drop, the sensitivity of your teeth seems to rise? In cooler conditions, it’s not unusual to experience more sensitivity than normal in your teeth.

Here’s why colder weather can make teeth feel more sensitive - and what to do if you’re suffering from the pain and discomfort of sensitive teeth.

Why does cold weather make teeth more sensitive?

In cold temperatures, the dentin layer located inside your teeth’s enamel expands and contracts faster than the enamel itself, which can cause tiny cracks to form.

While these cracks aren’t usually visible or damaging to your teeth, the fluid that moves inside the tiny tubes found in the dentin becomes more exposed, which in turn makes your teeth feel more sensitive.

In addition, if you tend to be extra sensitive to the cold in general, you may be clenching your teeth due to tensing. This can also cause sensitivity, as well as toothache and a sore jaw.

What other factors can cause sensitive teeth?

Many people experience sensitive teeth in all weather conditions, so clearly it’s not just the cold that’s to blame for sensitivity.

Sensitive teeth can result from a wide range of issues, including:

  • Tooth or gum infections
  • Cracked or damaged teeth
  • Periodontal disease
  • Grinding or clenching your teeth
  • Defective fillings, crowns or bridges
  • Cavities which require treatment
  • Large metal fillings
  • More serious oral health conditions, including some cancers

What should I do if I have sensitive teeth?

If you’re experiencing ongoing or painful sensitivity in your teeth, it’s important to see your National Dental Care dentist. Your dentist will look at your dental history and check your teeth and mouth to identify the cause of your sensitivity.

Treatment for sensitive teeth can range from a simple checkup and clean with oral hygiene training to X-rays and more extensive dental work if required.
