Tooth sensitivity causes a sharp, short pain with hot, cold, sweet or acidic foods. It happens when the protective enamel wears down or gums recede, exposing the sensitive layer beneath. It’s common and treatable at Astra Dental Care.
Common causes
- Enamel erosion from acidic foods or hard brushing
- Gum recession exposing the root
- Cavities or cracked teeth
- Teeth grinding
- Recent dental work (usually temporary)
Treatment & relief
Use a desensitising toothpaste and a soft brush, and avoid acidic foods. In the clinic, fluoride application, bonding or treating the underlying cavity/gum issue provides lasting relief. Persistent sensitivity should be checked — it can signal decay or a crack.
