Tooth Sensitivity (Hot/Cold Pain)
A short, sharp pain when teeth meet hot, cold, sweet or acidic triggers — usually treatable once the cause is known.
Overview
Tooth sensitivity — also called dentine hypersensitivity — produces a brief, sharp pain when teeth contact a trigger such as cold, heat, air, sweetness or acidity. It happens when the softer dentine layer becomes exposed, allowing fluid movement inside microscopic tubules to stimulate the nerve.
The underlying reason for exposure varies: gum recession, enamel erosion, a small crack, early decay, or worn fillings can all lead to similar symptoms. Identifying the correct cause is essential because the treatment differs accordingly.
We take time to examine, test and image the affected teeth, then recommend the most appropriate combination of desensitising care, protective restorations, gum management or lifestyle changes.
Common symptoms
- Sharp pain with cold drinks
- Discomfort with hot food
- Pain when breathing in cold air
- Discomfort during brushing
- Pain from sweet or sour foods
Common causes
- Gum recession exposing the root
- Enamel erosion or abrasion
- Cracked tooth or fractured restoration
- Early decay
- Brushing too hard or with a stiff brush
Our approach
Comprehensive examination
We begin with a focused clinical examination, digital X-rays where indicated, and a full medical and dental history to build a complete picture of your symptoms.
Transparent diagnosis
You receive a clear explanation of what we find, shown on-screen with intra-oral imaging so you can see exactly what we see — no jargon, no pressure.
Options-based treatment plan
We present all suitable treatment options with realistic outcomes, timings and written costs so you can make an informed decision at your own pace.
What you can do at home
Practical pointers — not a replacement for clinical assessment.
- Use a soft-bristle brush and gentle technique
- Try a desensitising toothpaste for 2–4 weeks
- Avoid very hot or cold foods temporarily
- Limit acidic drinks and use a straw
Related conditions
Receding Gums
Gum tissue moving away from the tooth — multiple causes, each with a different management path.
Enamel Erosion
Gradual loss of the tooth's protective outer layer from repeated acid exposure — enamel does not grow back.
Cracked Tooth
An incomplete fracture in a tooth that often causes sharp pain when biting — invisible on routine X-rays.
Early Decay
The earliest visible signs of enamel breakdown — reversible with a structured prevention plan.
