If your crown fell off, you’re not alone — it happens more often than you might think. While dental crowns are designed to last for years, several factors like decay, wear, or trauma can cause them to loosen or detach.
At Higher Ground Dentistry in Upland, CA, we’re here to help you understand why it happens and how to fix it quickly and safely.
Is It Common for Dental Crowns to Fall Off?
Dental crowns are strong and durable, but certain factors can cause them to loosen over time. If your crown falls off, it doesn’t necessarily mean your dental work failed — it just needs attention.
According to the American Dental Association, dental crowns are designed to last many years with proper care, but issues like decay or grinding can occasionally cause them to come loose.

Why Your Crown Fell Off — Common Causes
- Decay around the crown: New decay can weaken the bonding surface.
- Wear and tear: Teeth grinding (bruxism) or chewing hard foods can cause loosening.
- Bonding failure: Old or weak dental cement may lose its grip.
- Injury or trauma: Accidents or sports injuries can dislodge a crown.
- Aging materials: Over time, porcelain or ceramic crowns can wear down.

How Long Can You Go After a Crown Fell Off?
If your crown falls off, it’s best to call your dentist right away. The exposed tooth underneath is vulnerable to damage, decay, and sensitivity.
Here’s why you shouldn’t delay:
- The tooth is unprotected, making it prone to infection.
- You may experience pain or sensitivity when eating or drinking.
- The longer you wait, the more structural damage the tooth could suffer.
If you can’t visit immediately, use temporary dental cement (available at most pharmacies) to protect the area. But this is not a permanent solution — schedule a visit as soon as possible.
“If your crown fell off unexpectedly, visit our Upland emergency dentist today.”
If your crown has come loose or fallen off, avoid chewing on that side until you see your dentist.
If your tooth is exposed:
- Stick to soft foods like soups, yogurt, or smoothies.
- Avoid hot, cold, or sticky foods that could cause pain.
If you temporarily reattached the crown:
- Be gentle while chewing.
- Avoid nuts, hard candies, or ice.
Your dentist will evaluate whether your crown can be reattached or replaced based on the condition of your tooth and the crown itself.
How Easy Is It to Lose a Crown?
It’s not easy for a properly placed crown to fall off — but certain habits can increase the risk:
- Poor oral hygiene leading to decay.
- Teeth grinding or clenching (bruxism).
- Eating sticky or hard foods.
- Accidental trauma.
If you know you grind your teeth, consider asking about a custom nightguard to protect your crown and other restorations.

Can I Reattach a Crown Myself?
You can use temporary dental cement to hold the crown in place briefly, but do not attempt to permanently glue it yourself.
Here’s why:
- It’s only a temporary fix.
- Improper bonding can cause tooth damage or infection.
- Only a dentist can ensure the proper fit and seal.
If your crown falls off, call your dentist immediately — they’ll check for decay, clean the area, and reattach or replace the crown safely.
