Why your teeth feel sensitive — and when it matters
Dr. Vikram Mehta · 28 July 2026 · 5 min read
Cold water twinges are common, but not all sensitivity is the same. How dentists tell harmless from urgent.
Sensitivity has several causes
Exposed dentine from gum recession, enamel wear from aggressive brushing, a cracked filling and early decay can all produce similar symptoms. That is why a diagnosis matters more than switching toothpaste.
The pattern tells us a lot. A brief twinge that disappears immediately usually points to exposed dentine. Pain that lingers for thirty seconds or wakes you at night is more concerning and should be examined.
Small changes that help
Use a soft-bristled brush and a light grip, avoid brushing straight after acidic drinks, and give desensitising toothpaste at least four weeks before deciding it has not worked.
If sensitivity is limited to one tooth, that single-tooth pattern is worth a check-up regardless of severity.
What a check-up involves
We test the tooth's response, examine existing restorations, and take a radiograph if the cause is not visible. Most cases resolve with conservative treatment; a smaller number need restorative or endodontic care.
