Tooth sensitivity — a sharp, sudden twinge when you eat or drink something cold, hot, sweet or acidic — happens when the protective enamel thins or the gum recedes, exposing the softer dentine and the nerve beneath.
Common causes
- Enamel worn down by acidic food and drink
- Gum recession that exposes the tooth root
- Brushing too hard or with a stiff brush
- A cracked or chipped tooth
- Tooth decay or a worn filling
- Temporary sensitivity after whitening
What helps
- Use a desensitising toothpaste regularly
- Switch to a soft brush and a gentle technique
- Cut back on acidic foods and fizzy drinks
- Don’t brush immediately after acidic food — wait about an hour
- Use fluoride toothpaste to help strengthen enamel
When to see a dentist
If sensitivity lasts more than a week or two, is focused on one tooth, or is severe, see a dentist — it can signal decay, a crack or significant gum recession that needs treatment. We can apply fluoride, seal exposed areas or restore a damaged tooth, and a routine check-up and cleaning will pinpoint the cause.
