Symptom
Tooth sensitive to hot and cold
Sensitivity to hot or cold may be temporary, or it may point to a problem. Here is how to interpret it.
Possible causes
- Worn enamel or receding gums
- Tooth decay
- Inflammation of the pulp (the nerve)
- Cracked tooth
When to see a dentist
If the sensitivity lasts, gets worse or continues after the hot or cold has been removed, an assessment is recommended: it may point to damage to the pulp that requires root canal treatment.
