My new crown is sensitive to cold
Brief cold sensitivity after a new crown can come from an irritated pulp or exposed dentin, but lingering or worsening pain needs review.
The short answer
Cold sensitivity after crown placement can be temporary irritation of the pulp or dentin, but pain that lingers, worsens, or starts spontaneously needs examination.

What is the direct answer?
What does this question mean?
Preparing a tooth removes enamel and may expose dentin near the pulp. Cementation, drying, a leaky margin, a high bite, decay, or pre-existing pulp inflammation can affect symptoms. The crown itself does not contain a nerve, but the tooth beneath it does.
What can you do next?
Avoid very cold foods for now, chew on the opposite side, brush gently, and note how long the sensation lasts after the cold is removed. Do not repeatedly test the tooth or alter the crown yourself.
When should you seek dental care?
Contact the treating dentist if sensitivity lingers after the stimulus, interrupts sleep, increases, or is accompanied by biting pain. Urgent care is needed for swelling, fever, drainage, or a loose crown.
What should you ask the dentist?
Ask whether the bite and crown seal are correct, whether the pulp responds normally to testing, and what symptoms would indicate adjustment, observation, root canal treatment, or replacement.
Frequently asked questions
How long should cold sensitivity last?
The expected course depends on the tooth and procedure; persistent, lingering, or worsening pain should be reviewed.
Can a bite adjustment help?
If the crown contacts too early, a conservative adjustment may reduce overload, but it will not treat an inflamed pulp or decay.
