My crown is sensitive to cold
Cold sensitivity under or around a crown may come from exposed tooth structure, a leaking margin, bite stress, or inflamed pulp.
The short answer
A crown covers the visible part of a prepared tooth, but the natural root and pulp remain beneath it. Cold can reach exposed dentin at the crown edge, or it can trigger an inflamed pulp if decay, leakage, or a crack is present.
Which parts of a crowned tooth can react to cold?
This describes the anatomy and mechanism involved, including the tissues or material that can explain the finding.
What should I do about cold sensitivity under a crown?
Keep the area clean, avoid aggravating triggers, and arrange an examination so the clinician can inspect, test, and image it when indicated.
When can cold sensitivity under a crown be urgent?
Seek prompt care for persistent or worsening symptoms, and urgent assessment for facial swelling, fever, or difficulty swallowing or breathing.
What tests can identify the cause of cold sensitivity?
Ask what structure is affected, which examination or image is needed, and which treatment addresses the cause.
Frequently asked questions
Can home care replace an examination?
Home care may ease irritation, but the underlying cause determines whether dental treatment is needed.
What should I mention at the visit?
Describe when it began, where it occurs, its triggers, duration, and any recent dental work or injury.
