How Frequently Do Dental Crowns Fall Out?
Dental crowns are one of the most reliable and durable solutions in restorative dentistry. They’re designed to protect damaged teeth, restore function, and enhance aesthetics. However, like any dental restoration, crowns can occasionally become loose or fall out.
If you’ve ever wondered, “How often do dental crowns fall out?” or “Is this something I should worry about?”—this blog will answer your questions and help you understand why it happens, how often, and what you can do to prevent it.
How Often Do Dental Crowns Fall Out?
The good news is that dental crowns don’t fall out frequently—especially when they’re placed by an experienced dentist and cared for properly. With good oral hygiene and regular dental visits, most crowns stay in place for 10–15 years or longer.
That said, it’s not uncommon for a crown to become loose or fall out due to certain factors. While there aren’t exact statistics for how often this happens, studies suggest that crown failure rates range from 5–10% over a 10-year period.
Why Do Dental Crowns Fall Out?
There are several reasons why a dental crown might become loose or fall off:
1. Tooth Decay Under the Crown
If decay develops on the natural tooth underneath the crown, it can weaken the tooth structure, causing the crown to loosen.
2. Cement Failure
Dental crowns are bonded with a special dental cement. If this bonding agent fails due to wear, moisture, or improper application, the crown may detach.
3. Wear and Tear or Trauma
Grinding your teeth (bruxism), chewing on hard objects (ice, pens), or experiencing a blow to the face can weaken or dislodge a crown.
4. Poor Fit or Improper Placement
Crowns that were not fitted properly or were placed over insufficient tooth structure may not have the stability they need to last.
5. Gum Recession
Over time, gum recession can expose the margin of the crown, increasing the risk of decay and reducing retention.
What Should You Do If Your Crown Falls Out?
If your dental crown falls out, don’t panic. Here are the steps to take:
- Recover the Crown (if possible) and keep it clean.
- Call your dentist immediately for an appointment.
- Avoid chewing on that side of your mouth until it’s repaired or replaced.
- Use temporary dental cement (available at most pharmacies) if you can’t get to the dentist right away.
Your dentist will assess the situation to see if the crown can be re-cemented or if a new one is needed.
How to Prevent Dental Crowns from Falling Out
While you can’t always prevent unexpected accidents, these tips can help you keep your crown secure and long-lasting:
- Maintain excellent oral hygiene – Brush and floss daily to prevent decay.
- Avoid chewing hard foods or using your teeth as tools.
- Wear a night guard if you grind or clench your teeth.
- Visit your dentist regularly for cleanings and check-ups.
- Follow all care instructions provided by your dental provider.
While dental crowns are not likely to fall out often, it can happen under certain conditions. The key to keeping your crown secure is proper care, regular dental visits, and addressing any issues early. If a crown does fall out, prompt dental attention can usually resolve the issue quickly and comfortably.
