5 Common Causes of Tooth Sensitivity (and How to Fix Them)

1. Enamel Erosion

Enamel is the protective outer layer of your teeth. Over time, brushing too hard, acidic foods, or natural wear can erode enamel, exposing the sensitive dentin beneath.
Fix it: Use a soft-bristled toothbrush, fluoride toothpaste, and limit acidic food and drink. A demineralizing toothpaste can also help strengthen enamel.

2. Gum Recession

When gums recede, the roots of your teeth—normally covered and protected—become exposed. This can trigger sensitivity, especially to cold or touch.
Fix it: Gentle brushing, proper flossing, and regular dental cleanings help prevent further recession. In more advanced cases, a gum graft may be recommended.

3. Tooth Decay or Worn Fillings

Cavities and damaged fillings can leave parts of your teeth vulnerable. If decay reaches the dentin, sensitivity to sweets, heat, or cold is common.
Fix it: Early treatment with fillings or bonding can protect the area. Regular exams help catch decay before it causes discomfort.

4. Teeth Grinding (Bruxism)

Clenching or grinding wears down enamel and stresses the tooth structure, making teeth more reactive to temperature changes and pressure.
Fix it: A custom night guard can protect your teeth while you sleep and help reduce jaw tension.

5. Post-Treatment Sensitivity

It’s not uncommon to feel temporary sensitivity after cleanings, fillings, or whitening treatments. This usually resolves within a few days.
Fix it: Use a desensitizing toothpaste and avoid extreme temperatures. If discomfort persists, let your dentist know—it could signal an underlying issue.
