Can a crown be reused after it comes loose?
Often yes. A crown that is intact can usually be cleaned and recemented when the tooth underneath is sound and its shape has not changed. It usually cannot be reused when part of the tooth broke off inside the crown, decay has changed the tooth, the crown is cracked or bent, or it has come off repeatedly; then a new crown, a build-up, root canal treatment or, if the tooth has split, extraction may be discussed.
Only an examination with an x-ray decides.
Emergency routing first
If you inhaled the crown and are coughing or short of breath, that is an emergency. A swallowed crown without symptoms is reported to the office and your physician.
If any of these apply, this is not a dental-office problem first: trouble breathing or swallowing, rapidly spreading swelling of the face or neck, fever with facial swelling, bleeding that will not stop, or a serious injury to the head or jaw. Call 911 or go to the nearest emergency department. Do not use the appointment request form for these.
What to do now
Keep the crown clean and dry in a container. Do not use household glue. Chew on the other side. Avoid very hot, cold or sweet foods. Call the office during listed hours and ask before using any over-the-counter temporary cement. The American Dental Association's emergency guidance covers lost crowns (ADA).
What the examination checks
- Is there tooth inside the crown? A fragment means the tooth has changed shape
- Decay on the exposed tooth
- Cracks in the tooth
- Whether the crown is intact and seats fully
- Why it came off: washed-out cement, decay, a bite problem, grinding
Expected versus call-the-office
| Expected after a crown comes off | Call the office |
|---|---|
| Sensitivity to cold and sweet | Lingering or throbbing pain |
| Rough feel | Sharp edge cutting the tongue |
| Crown clean and whole | Tooth fragment inside the crown; crown cracked |
| Comfortable chewing on the other side | Swelling, bad taste, or a gum pimple |
If it cannot be reused
Options depend on what remains: a build-up and new crown, root canal treatment if the nerve is involved, or extraction and replacement if the tooth has split. The Oral Health Foundation describes crowns and what happens when they fail (OHF). Costs are discussed at the visit; this page does not state fees.
Next step: Request a consultation or call (805) 565-5111. A request is not a confirmed appointment; the office confirms times during its listed hours (Monday to Thursday, 8 am to 5 pm, plus select Fridays).
