You’ve just been to the dentist and were given a clean bill of dental health. Yet, you can’t shake the tooth sensitivity this winter! We understand. The cold months are hard on our bodies and our teeth.

Why Teeth Are More Sensitive in Cold Weather

Teeth may be more sensitive during the cold months for several reasons. Here are a few of the most common:

 

  • Mouth Breathing: If you have a stuffy nose and breathe through your mouth, you introduce cold air to your teeth, which can dry them. The cold air and dryness can lead to sensitive teeth and even present a cavity risk.
  • Expanding Restorations: Restorations containing metal can expand or contract when cold, which can mean tooth sensitivity and even new areas of decay during winter.
  • Sugary Cough Medications: Some cough syrups contain copious amounts of sugar to bury the horrible taste. Sugar can lead to tooth sensitivity, especially if enamel is compromised.
  • Teeth Whitening: Teeth whitening products can mean tooth sensitivity over time, and many people start whitening in winter to enjoy a bright summer smile later.

Ways to Eliminate Tooth Sensitivity in the Cold Months

You can eliminate or reduce tooth sensitivity in winter. Below, we share a few tips. However, be sure the dentist first evaluates your smile because sensitivity can indicate an infection or cavity.
