Crown tooth sensitive to hot and cold
A crowned tooth that reacts to hot or cold may have exposed dentin, a loose margin, decay, or inflammation in the pulp.
Why can a crowned tooth react to hot and cold?
A crowned tooth that reacts to hot or cold may have exposed dentin, a loose margin, decay, or inflammation in the pulp.
What does a dental crown cover on the prepared tooth?
A dental crown covers the visible part of a prepared tooth with ceramic, zirconia, metal, or a layered combination. Temperature can reach the tooth through a gap, thin remaining enamel or dentin, a receding gum, or a pulp that is inflamed beneath the crown.
What can you do about brief cold sensitivity?
A brief cold response may come from exposed dentin at the gumline. Lingering heat pain can indicate pulpal inflammation.
When should hot or cold sensitivity be assessed?
A dentist may test the pulp and inspect the crown margin. Arrange an examination if the problem persists or interferes with eating, sleep, or normal oral care.
What should you ask about sensitivity beneath the crown?
Ask what finding explains the symptom, whether the tooth or gum needs testing, and which treatment addresses the cause. Share medicines, pregnancy status, allergies, and relevant medical conditions.
Frequently asked questions
Can a crown need a root canal?
Yes. If the pulp is irreversibly inflamed or infected, root canal treatment can often be performed through the crown.
Why does cold pain linger?
Pain that continues after the cold is removed can reflect pulpal inflammation and needs examination.
