Lost Filling or Crown
Temporary Relief and Emergency Dental Repair
What Is a Lost Filling or Crown?
Losing a filling or crown exposes the underlying tooth structure, which can be very sensitive and vulnerable to further damage or decay. While not always immediately dangerous, it should be treated within 24–48 hours to prevent complications.

Frequently Asked Questions
Can I reattach a crown myself?
Temporarily, yes — dental cement from a pharmacy can hold a crown in place until you see a dentist. Never use super glue. This is a temporary fix only; you still need professional dental care.
What if I swallowed my crown?
If swallowed, a crown will typically pass through your system without harm. Call your dentist to get a replacement made. If you experience chest pain or difficulty breathing, seek emergency medical care.
Why did my filling fall out?
Fillings can fail due to age, decay around the filling, grinding teeth, or biting hard foods. Once a filling falls out, the exposed tooth is vulnerable to new decay — prompt replacement is important.
Within 24–48 hours; same day if pain is severe
