Is It a Cavity? How to Tell
Sensitivity to hot, cold, or sweets in one specific tooth is the most common early sign of a cavity.
What a cavity typically feels like
A brief sharp twinge when eating or drinking something cold or sweet, localized to one tooth, is classic. As decay progresses, pain can become more constant.
What else it could be
Widespread sensitivity across many teeth is more often linked to enamel wear or gum recession than a single cavity.
What to do next
A routine dental visit with an X-ray is the only reliable way to confirm — the earlier it's caught, the simpler the fix.
Key takeawayLocalized sensitivity in one tooth = likely cavity. Book a routine check before it progresses.
