Lost a Filling or Crown: How Urgent Is It?

Crown came off with a broken tooth.
A crown that comes off isn’t always on a front tooth. In this case, there was no remaining tooth structure beneath the crown, so the patient received a dental implant to replace the tooth.

Losing a filling or crown can be unsettling, especially if it happens while eating or brushing and doesn’t hurt right away. Many patients wonder whether this is something that can wait or if it needs immediate attention.

The answer depends on what’s exposed and how long it’s left untreated.

Why Fillings and Crowns Matter

Fillings and crowns protect weakened or damaged teeth. When one comes out, the tooth underneath may be exposed to:

  • Sensitivity to temperature or pressure
  • Bacteria that can cause further decay
  • Cracks or fractures from chewing forces

The common reason why existing crowns or filling come off is because there is an on going cavity (soft tooth structure) underneath the filling or crown.

Even if you’re not in pain, the tooth is often more vulnerable than it looks.


Is Losing a Filling an Emergency?

A lost filling is not always an emergency, and it should be addressed as soon as possible, especially if:

  • The tooth feels sensitive or sharp
  • Food keeps getting trapped
  • You notice pain when chewing

Without protection, decay can progress quickly, sometimes turning a simple repair into a more complex treatment.


What If a Crown Falls Off?

A lost crown is usually more urgent than a lost filling, especially if:

  • The tooth underneath is sensitive
  • The crown came off with decay attached
  • The tooth looks cracked or worn down

Crowns are designed to protect structurally weakened teeth. Leaving the tooth uncovered increases the risk of fracture, which may limit treatment options later.


What You Can Do Right Away

If you lose a filling or crown:

  • Keep the area clean
  • Avoid chewing on that side
  • Save the crown if it came off intact
  • Temporary dental cement (from a pharmacy) – we don’t recommend this option. It is safer to see a dentist than DIY dentistry at home

Especially avoid using glue or household adhesives.


What Happens If You Wait Too Long?

Delaying care can lead to:

  • New decay under the restoration
  • Tooth fractures
  • Increased sensitivity or infection
  • Needing a larger restoration, or even extraction

Addressing the issue early is usually simpler, more comfortable, and less costly.


When to See a Dentist

You should schedule a dental visit if:

  • A filling or crown has fallen out
  • The tooth feels sensitive or uncomfortable
  • You’re unsure whether it needs treatment

Even if there’s no pain, an evaluation helps prevent small problems from becoming bigger ones.
