What can I do if my filling or crown fell out?
A lost filling or crown isn't usually an emergency, but the exposed tooth is vulnerable and should be seen by a dentist soon. Here's how to protect it and stay comfortable in the meantime.

Call 911 or go to the ER for these signs
Some dental problems are medical emergencies. Get emergency care right away if you have:
- Difficulty breathing or swallowing
- Swelling of the face, jaw, floor of the mouth, or neck — especially if it is spreading
- Swelling that affects your eye or makes it hard to open your mouth
- A high fever combined with mouth or facial swelling
- Bleeding that won't stop after 10–15 minutes of firm pressure
- A knocked-out adult tooth, or an injury to the jaw, head, or face
When in doubt, consider it an emergency and seek care now.
Losing a filling or crown exposes part of the tooth that was protected, which can make it sensitive and more prone to damage. It’s usually not an emergency, but the tooth should be seen soon. This is educational information, not a diagnosis — a dentist needs to examine the tooth and decide how to restore it.
What to do now
- Keep the crown if you have it — rinse it and store it safely to bring to your appointment.
- Keep the area clean by rinsing with warm water and brushing gently.
- Avoid chewing on that side and steer clear of very hot, cold, hard, or sugary foods that trigger sensitivity.
- For a clean, intact crown, over-the-counter temporary dental cement may hold it in place briefly — but see a dentist to have it properly re-cemented. Never use household glue.
- Book a dental visit soon, sooner if there’s pain.
Why not to wait too long
Without its filling or crown, the tooth is more exposed to decay and breakage, and a small problem can turn into a bigger one. A prompt visit usually means a simpler repair.

Frequently asked questions
Is a lost filling or crown an emergency?
Usually not, but it should be seen promptly. The exposed tooth can be sensitive and is more vulnerable to damage or decay. Seek urgent care if you have severe pain, swelling, or signs of infection.
Can I put my crown back on myself?
Only a dentist should re-cement a crown. Over-the-counter temporary dental cement may hold a clean, intact crown in place briefly until you're seen, but it isn't a permanent fix — never use household glue.
How do I protect the tooth until my appointment?
Keep the area clean, avoid chewing on that side, and avoid very hot, cold, or sugary foods that trigger sensitivity. If you have the crown, keep it and bring it with you.
