Lost a Crown or Filling? Don't Panic — Read This First


The Crown Fell Off — Now What?
It happens at the most inconvenient times. You're eating dinner and you feel something hard in your mouth — your crown has come off. Or you're brushing your teeth and notice that an old filling is missing. While the experience can be alarming, the good news is that losing a crown or filling is a manageable situation — as long as you handle it correctly and seek care promptly. This guide covers exactly what to do the moment you lose a crown or filling, how to protect the tooth until you're seen, and why calling American Urgent Dental should be your next step.
Why Crowns and Fillings Fall Out
DECAY UNDERNEATH: New decay forming under or around a crown or filling compromises the bond, causing it to loosen and fall out. This is the most common cause — and means the underlying tooth needs attention beyond just recementation.
CEMENT FAILURE: The cement bonding a crown has a finite lifespan. Over years of biting forces and thermal changes, the bond gradually weakens.
PHYSICAL STRESS: Biting something very hard, sticky foods (taffy, caramel, chewing gum), or teeth-grinding can dislodge a crown or fracture a filling.
OLD AGE OF THE RESTORATION: Fillings and crowns don't last forever. An amalgam filling placed 20 years ago may simply be at the end of its lifespan.
FRACTURE OF THE TOOTH UNDERNEATH: If the tooth under a crown fractures, the crown may lift or shift as a result.
Is This an Emergency? How to Tell
REQUIRES IMMEDIATE SAME-DAY CARE: • Significant pain — the exposed tooth is extremely sensitive to air, touch, temperature, or pressure • A jagged, broken tooth edge cutting your tongue or cheek • Visible decay or darkening at the tooth surface exposed by the lost filling • The crown was on a front tooth and affected your ability to speak or eat • The crown appears to have come off because the tooth underneath broke
CAN BE SEEN WITHIN 24–48 HOURS: • Little to no pain when the crown or filling fell out • Mild temperature sensitivity that is manageable • The restoration is intact and you saved it • No sharp edges causing tissue injury
Even in lower-urgency scenarios, call us as early as possible. An exposed tooth without its protective restoration is vulnerable to bacteria, temperature changes, and fracture.
Immediate Steps After Losing a Crown
SAVE THE CROWN: Find it, rinse gently under cool water, and keep it safe in a small container or zip-lock bag. If intact and the tooth is also intact, the crown can often be re-cemented the same day.
TRY TEMPORARY RECEMENTATION: Dental cement brands like Dentemp, Recapit, or TempBond are available at most pharmacies. Clean the crown and tooth, dry them, place a small amount of cement inside the crown, and press it firmly onto the tooth biting gently to seat it. Remove excess cement. Do not eat for 30 minutes. This is a temporary solution — call us for permanent recementation.
IF YOU DON'T HAVE DENTAL CEMENT: A small piece of sugar-free chewing gum can serve as a very temporary placeholder to reduce sensitivity.
DO NOT USE SUPER GLUE — ever. Super glue is toxic in the mouth, cannot be safely removed by a dentist, and often results in a misaligned crown that traps bacteria and causes more damage. Patients who super-glue crowns often end up needing entirely new crowns rather than a simple recementation.
Immediate Steps After Losing a Filling
MANAGE SENSITIVITY: A lost filling exposes dentin — the sensitive layer beneath enamel. Ibuprofen helps with aching. Temporary dental cement can fill the void and reduce sensitivity. Avoid temperature and dietary triggers.
CLEAN CAREFULLY: Brush and floss gently around the area — don't skip brushing even though it's sensitive. Food debris packing into the open cavity accelerates decay significantly.
DO NOT USE SUPER GLUE: We see this more than you'd expect. Household adhesives are toxic in the mouth, cannot be safely removed, and trap bacteria, dramatically worsening the decay problem.
What Happens When You Come In to American Urgent Dental
ASSESSMENT AND X-RAYS: We examine the exposed tooth and the restoration you saved. X-rays check for decay underneath, assess pulp health, and evaluate whether the crown or filling can be reused.
TREATMENT OPTIONS: • Crown recementation: If the crown is intact and the tooth is healthy — same-day, often under 30 minutes. • New filling or buildup: If significant decay exists under the old filling or crown, we remove decay first, then recement or fabricate a new crown. • Root canal + new crown: If decay has reached the pulp, root canal therapy is needed before the tooth can be re-crowned. • New crown fabrication: If the old crown is damaged, a new crown is needed. We place a temporary crown the same day while your permanent crown is fabricated (typically 2–3 weeks).
Preventing Crown and Filling Loss in the Future
- Avoid chewing ice, hard candy, and very hard foods on crowned or heavily filled teeth
- Avoid sticky foods that can pull restorations loose
- Wear a nightguard if you grind your teeth — grinding is one of the most common causes of crown and filling failure
- Maintain excellent oral hygiene — keep the margins of crowns and fillings clean to prevent decay from undermining them
- See your dentist for regular check-ups — restorations that are wearing or loosening can often be addressed before they fail completely
The financial case for acting promptly is clear: a crown recemented the day it falls out may involve only a simple recementation fee. The same situation left for a week may result in decay requiring a full new crown, multiplying the cost several times.
