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.

What does this question mean?
This describes the anatomy and mechanism involved, including the tissues or material that can explain the finding.
What can you do next?
Keep the area clean, avoid aggravating triggers, and arrange an examination so the clinician can inspect, test, and image it when indicated.
When should you seek dental care?
Seek prompt care for persistent or worsening symptoms, and urgent assessment for facial swelling, fever, or difficulty swallowing or breathing.
What should you ask the dentist?
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?
