Front teeth crown sensitivity
Sensitivity beneath a front crown can come from exposed dentine, an irritated pulp, a leaking margin, gum recession, or a heavy bite.
The short answer
Sensitivity beneath a front crown can come from exposed dentine, an irritated pulp, a leaking margin, gum recession, or a heavy bite. A crown covers the visible tooth but does not remove the pulp unless root canal treatment was performed; cold sensitivity and biting pain have different causes.

What does this question mean?
A crown covers the visible tooth but does not remove the pulp unless root canal treatment was performed; cold sensitivity and biting pain have different causes.
What can you do next?
Use a soft brush and desensitizing toothpaste, avoid extreme temperatures, and do not ignore a crown that feels high or mobile.
When should you seek dental care?
Seek examination for spontaneous pain, lingering heat or cold pain, swelling, a darkening tooth, or worsening symptoms.
What should you ask the dentist?
Ask whether the sensitivity is from the gum, cement margin, bite, pulp, or adjacent tooth and whether an X-ray or bite test is needed.
Frequently asked questions
Can this be treated without identifying the cause?
Treatment depends on the examination finding, so symptom relief does not replace diagnosis.
What information helps at an appointment?
Note when the symptom began, what triggers it, recent dental work, and the medicines you use.
