Why Are My Teeth Sensitive to the Cold?

If a deep breath of chilly air makes your teeth twinge, you’re not imagining things. Cold weather can trigger tooth sensitivity, especially for those with certain dental conditions. At Toland Dental in Wynne, AR, Dr. Richard Toland often hears this question as temperatures drop: “Why do my teeth hurt when I go outside in the cold?”

Let’s explore what causes this seasonal sensation — and how to keep your smile comfortable when the forecast calls for freezing.

Why Cold Air Affects Your Teeth

Your teeth are living structures, with nerves and blood vessels inside. The outer enamel is meant to protect those sensitive inner layers. But when enamel wears down or gums recede, the inner dentin layer is exposed — and that’s where cold air becomes a problem.

Dentin contains tiny tubules that lead directly to the nerve. Cold air can travel through these tubules and send a quick jolt to the nerve, resulting in that sharp, uncomfortable sensation.

And unlike sipping a cold drink, exposure to winter air can be constant — especially if you breathe through your mouth while walking or working outside.

Common Causes of Cold Air Sensitivity

• Worn Enamel: Brushing too hard, grinding, or acidic foods can wear down enamel and reduce insulation.
• Gum Recession: Exposed roots are more sensitive to cold because they lack protective enamel.
• Cracks or Chips: Even tiny cracks can let cold air reach the nerves inside your teeth.
• Tooth Grinding (Bruxism): Increases risk of enamel wear, cracks, and sensitivity.
• Recent Dental Work: Fillings, crowns, or whitening can cause temporary cold sensitivity.

What You Can Do About Cold Sensitivity

While some cold sensitivity is common in winter, it shouldn’t be painful or disruptive. If it’s affecting your daily routine, it’s time to take action:

• Switch to a Sensitivity Toothpaste: Use consistently to help block nerve pathways.
• Brush Gently with a Soft Brush: Avoid further enamel erosion and gum damage.
• Wear a Scarf Over Your Mouth: Shield your smile when breathing cold air outdoors.
• Cut Back on Acidic Foods and Drinks: Rinse with water and wait before brushing.
• Use a Nightguard (If You Grind): Protect your teeth from clenching-related damage.

When to See a Dentist

If your cold sensitivity is new, worsening, or interfering with your daily life, it could signal an issue that needs attention, such as:

• A developing cavity
• A cracked or fractured tooth
• Gum disease or root exposure
• Failing dental work

At Toland Dental, Dr. Richard Toland can examine your teeth and determine the exact cause. Depending on the issue, treatment options might include fluoride varnish, bonding to cover exposed dentin, or addressing gum recession.

Keep Your Smile Comfortable in Every Season

Cold air shouldn’t keep you from enjoying winter. If you’re feeling that familiar zing of sensitivity every time the temperature drops, there’s a good chance your teeth are trying to tell you something. With the right care, that discomfort doesn’t have to linger.
