Sensitive Teeth
Tooth sensitivity is a short, sharp pain when teeth meet hot, cold, sweet or sour things. It happens when the protective enamel or gum wears away.
Causes & risk factors
- Worn tooth enamel
- Receding gums exposing the tooth root
- Tooth decay or a cracked tooth
- Aggressive brushing
- Acidic foods and drinks
- Teeth grinding
Common symptoms
- Short, sharp pain with hot or cold
- Pain with sweet or sour foods
- Discomfort when brushing
- Sensitivity to cold air
- Twinges in one or several teeth
Tests & diagnosis
- Dental examination
- Dental X-ray to rule out decay
- Sensitivity testing
Treatment & management
- Using a desensitising toothpaste
- Brushing gently with a soft brush
- Cutting down on acidic foods and drinks
- Fluoride treatment at the dentist
- Treating any decay, cracks or gum recession
When to see a doctor urgently
- Sensitivity that is severe or getting worse
- Pain that lingers rather than a brief twinge
- Sensitivity in just one tooth (possible decay or crack)
- Sensitivity with swelling or visible damage

Frequently asked questions
Does sensitivity always mean a cavity?
Not always. It is often due to worn enamel or receding gums, but sensitivity in a single tooth or lingering pain can mean decay or a crack that needs checking.
How can I reduce sensitivity?
Use a desensitising toothpaste, brush gently with a soft brush, and cut down on acidic foods. See a dentist if it persists.
