A sudden zing of pain when drinking something cold is one of the most common dental complaints. This usually happens when the protective layers of your tooth become thinner or exposed.
‍

Why Cold Causes Pain

Inside each tooth are microscopic tubules connected to nerves. When exposed, cold temperatures stimulate these nerves directly.
‍

Common Causes

• Enamel wear from grinding
• Gum recession exposing root surfaces
• Tooth decay
• Recent whitening treatments
• Cracked teeth
  ‍

What Helps Immediately

• Switch to toothpaste for sensitive teeth
• Avoid acidic drinks temporarily
• Use lukewarm water instead of very cold
• Brush gently with a soft brush
  ‍

When It May Be More Serious

Contact a dentist if:

• Pain lingers after the cold stimulus
• Sensitivity worsens
• You feel spontaneous pain
  ‍

Next Step

Sensitivity is often manageable — but persistent pain may indicate decay or structural damage needing treatment.
