Why Do My Teeth Hurt When It’s Cold? Understanding Winter Tooth Sensitivity

Cold sensitivity often stems from exposed dentin (due to gum recession or enamel wear) and tiny fluid shifts inside tooth tubules that trigger nerves. Professional treatments—like desensitizing varnish, bonding, and bite adjustments—can provide lasting relief.

The Science of Sensitivity

When enamel thins or roots are exposed, temperature changes move fluid inside microscopic tubules, stimulating the nerve. Acidic drinks and aggressive brushing can worsen this.

Common Causes in MetroWest

  • Gum recession from brushing hard or periodontal disease
  • Enamel erosion from acids or grinding
  • Cracks or leaking fillings

Professional Solutions

  • Desensitizing varnish or prescription toothpaste
  • Bonding for exposed root surfaces
  • Nightguards for clenching/grinding
