Sensitivity is a short, sharp sensation triggered by cold, sweet foods or air. It is a symptom rather than a diagnosis, and the reason behind it needs to be identified.
Common causes
- Gum recession exposing the root surface
- Worn enamel from aggressive brushing or acidic diet
- Decay
- A cracked tooth or a failing filling
- Recent dental treatment, which usually settles
Management
Treatment depends on the cause found during examination and may involve changes to cleaning habits, desensitising measures, or restoring a tooth. Persistent or severe sensitivity should be assessed rather than managed indefinitely at home.
