In this article, we explain what tooth sensitivity is, its main causes, and how to manage it effectively.
What is tooth sensitivity?
Tooth sensitivity occurs when the dentin—the layer beneath your enamel—is exposed. Dentin contains tiny tubules that lead directly to the nerve of the tooth. When cold, heat, sugar, or acid reach these tubules, they trigger a short, sharp pain.
Common causes of tooth sensitivity
- Enamel erosion
Enamel protects your teeth. Overbrushing, acidic foods and drinks, or teeth grinding can wear it down, exposing the dentin.
- Gum recession
When gums recede, the root of the tooth is exposed. Unlike the crown of the tooth, roots are not covered by enamel and are more sensitive.
- Tooth decay or cracks
Cavities, damaged fillings, or cracks can create a direct path to the nerve, causing pain and sensitivity.
- Recent dental treatments
Procedures like deep cleaning, fillings, or whitening may cause temporary sensitivity.
- Whitening products
Overuse or misuse of whitening agents can temporarily increase sensitivity.
- Dentinal hypersensitivity
Sometimes, teeth can be naturally hypersensitive despite being healthy. In these cases, simply using a desensitizing toothpaste will help.
How to relieve tooth sensitivity
- Use a toothpaste designed for sensitive teeth
- Brush with a soft-bristled toothbrush and gentle technique
- Avoid acidic foods and temperature extremes
- Visit your dentist to identify and address the underlying cause
