A Calgary Dentist Explains Why Winter Makes Your Teeth Hurt — and What You Can Do About It

Winter in Calgary is beautiful, but for many people, it also brings an uncomfortable surprise: sharp, sudden tooth pain when breathing cold air or sipping a hot drink after coming in from outside.

As a dentist practicing in NE Calgary, I see a noticeable increase in patients complaining of cold-sensitive teeth during winter months.

The good news is that this sensitivity is common, manageable, and often preventable once you understand what’s causing it.

In this blog, I’ll explain:

  • Why teeth become more sensitive in winter
  • What sensitivity really means for your oral health
  • How to treat cold sensitivity at home
  • When it’s time to see a dentist
  • How we help patients manage tooth sensitivity at Jacksonport Dental

What Does Tooth Sensitivity Feel Like?

  • A sudden, sharp pain when breathing cold air
  • Discomfort when drinking hot tea or coffee after being outside
  • Pain when eating ice cream or cold foods
  • Sensitivity that fades quickly once the stimulus is removed

This type of pain is different from a constant toothache.

Why Are Teeth More Sensitive in Winter?

1. Cold Air Causes Tooth Expansion and Contraction

Cold air causes teeth to contract and expand repeatedly.

  • Stress the enamel
  • Expose microscopic cracks
  • Irritate the inner nerve of the tooth

2. Enamel Wear Exposes Dentin

When enamel wears down, dentin becomes exposed, allowing cold to reach the nerve.

  • Aggressive brushing
  • Acidic foods and drinks
  • Teeth grinding (bruxism)
  • Acid reflux
  • Natural aging

3. Gum Recession Exposes Sensitive Root Surfaces

Receding gums expose roots that lack enamel protection.

  • Tooth roots become exposed
  • Cold sensitivity increases

4. Teeth Grinding Increases During Stressful Winter Months

  • Shorter daylight hours
  • Holiday responsibilities
  • Work and family pressures

Bite guards & splints

5. Existing Dental Issues Become More Noticeable

  • Cavities
  • Cracked teeth
  • Old or failing fillings
  • Early gum disease
