Tooth sensitivity to hot or cold is a common concern, and it usually signals that the tooth’s protective layers have been compromised.
When enamel thins or gums recede, the underlying tooth structure becomes more exposed. This allows temperature changes to reach the nerve more easily, causing that sudden sharp sensation.
Sensitivity can be linked to enamel wear, grinding, gum recession, cavities, or even recent whitening treatments. The key is identifying why it’s happening — because the right solution depends on the cause.
If sensitivity is interfering with eating or drinking comfortably, a dental evaluation can help prevent it from getting worse and guide appropriate treatment.
