It happens more often than you would think. You are eating, biting down on something, and suddenly your dental crown comes loose or falls out completely. The first reaction for most people is panic. The second is: can you fix a crown that fell out?
The good news is, yes, in most cases a fallen crown can absolutely be fixed. Whether it gets re-cemented or replaced with a new one depends on a few factors. But the important thing to know right now is that this is not an emergency that should send you to the hospital. It is a dental situation that needs prompt attention, and the steps you take in the next few hours matter.
At Hollywood Family Dentistry in Portland, we see this regularly and we know exactly how to help. Here is everything you need to know about what to do when your dental crown falls out.
Can You Fix a Crown That Fell Out?
| Quick Answer: Yes, in most cases a dental crown that has fallen out can be fixed. If the crown is intact and the underlying tooth is healthy, your dentist can often re-cement it during a same-day visit. If the crown is damaged or the tooth has decayed, a new crown will need to be made. |
A crown falling out does not mean your tooth is ruined. It does mean you need to act quickly and smartly. The tooth underneath is now exposed, which makes it vulnerable to temperature sensitivity, bacteria, and physical damage from chewing.
The sooner you see your dentist, the better the outcome. Most of the time this is a straightforward fix.
What to Do Immediately When Your Crown Falls Out
Stay calm. You have options. Here is exactly what to do in the first few hours after your crown falls out.
First, find the crown if you can and rinse it gently with warm water. Do not scrub it or use any cleaning agents. Place it in a small container or zip-lock bag so you can bring it to your dental appointment. Your dentist will assess whether it can be reused.
Second, protect the exposed tooth. Avoid chewing on that side entirely. If the tooth is sensitive, you can apply a small amount of dental cement from a pharmacy kit or even a tiny bit of toothpaste to the exposed surface as a short-term measure. These are temporary fixes only and do not replace seeing your dentist.
Third, call your dentist as soon as possible. Most dental offices including Hollywood Family Dentistry in Portland will do their best to see you quickly for a fallen crown. It is considered an urgent dental issue.
Can the Same Crown Be Re-Cemented?
This is the question most patients ask first. The answer depends on the condition of both the crown and the tooth underneath it.
If the crown is still fully intact with no cracks or chips, and if the tooth it was covering is structurally sound with no new decay, there is a good chance it can simply be cleaned and re-cemented. This is the fastest and most cost-effective outcome.
However, if the crown fell out because the cement underneath wore down over time, that is a sign it may have been loose for a while. In that case your dentist will want to check the tooth carefully before re-attaching anything.
If the tooth beneath the crown has new decay, a crack, or other damage, a new crown will need to be fabricated. That process typically takes one to two weeks depending on whether your dentist uses same-day digital crown technology or a dental lab.
Why Do Dental Crowns Fall Out in the First Place?
Understanding why it happened can help prevent it from happening again. Crowns do not simply fall out randomly. There is almost always a reason.
The most common cause is simply cement failure. Dental cement is durable but not permanent. Over years of chewing, grinding, and exposure to saliva, the bond can weaken and eventually let go. This is especially common in crowns that are more than ten years old.
Decay underneath the crown is another frequent culprit. If bacteria have worked their way under the crown and caused the tooth to break down, there is nothing solid left for the crown to hold onto.
Physical trauma, biting down on something very hard, or grinding your teeth at night (bruxism) can also dislodge a crown. If you grind your teeth and have not yet looked into a night guard, it is worth discussing with your dentist at your next visit.
What Happens If You Leave a Crown Off Too Long?
Some people put off calling the dentist after a crown falls out, either because they are not in pain or because life gets in the way. This is understandable but risky.
A tooth that has been prepared for a crown has had its outer enamel trimmed down significantly. Without the crown protecting it, that tooth is fragile. It can crack under normal chewing pressure, become hypersensitive to hot and cold, or develop new decay quickly because the dentinal layer is now exposed.
The longer you wait, the more complex the fix may become. What could have been a simple re-cement could turn into a need for a root canal or even a dental implant if the tooth cannot be saved. Acting quickly is always the better choice.

What to Expect at Your Dental Appointment for a Fallen Crown
Walking in with a fallen crown is one of the more straightforward dental visits you can have. Here is a general idea of what your dentist will do.
Your dentist will first examine the exposed tooth using visual inspection and likely an X-ray to check the root and surrounding bone. They will also look at the crown itself to assess whether it is salvageable.
If re-cementing is possible, the dentist will clean both the inside of the crown and the tooth, apply fresh dental cement, and press the crown back into place. You will bite down gently to check the fit and the appointment is usually done within 30 to 45 minutes.
If a new crown is needed, impressions or digital scans of the tooth will be taken and sent to a lab. You will receive a temporary crown to protect the tooth in the meantime. The permanent crown is typically ready within one to two weeks.
The team at Hollywood Family Dentistry makes this process as straightforward and comfortable as possible. We take the time to explain every step so you always know what is happening and why.
How to Prevent Your Crown From Falling Out Again
Once your crown has been re-fitted or replaced, a few simple habits go a long way toward keeping it in place for years to come.
Avoid chewing on particularly hard items like ice, hard candy, or the end of pens. These put concentrated stress directly onto the crown. Similarly, sticky foods like caramel and certain chewing gums can exert a pulling force on the cement bond.
Maintaining good oral hygiene around the crown is also essential. Food and bacteria that accumulate at the gum line where the crown meets the tooth can slowly break down the cement and the tooth itself. Brushing twice daily and flossing carefully around the crown keeps the margin clean and the seal intact.
If you grind your teeth at night, ask your dentist about a custom night guard. Grinding puts enormous pressure on crowns over time and is one of the leading causes of premature crown failure.
Finally, do not skip your regular checkups. According to the American Dental Association, routine dental visits allow your dentist to spot early signs of cement failure, decay under a crown, or other issues before they become bigger problems.
Things You Should Never Do When a Crown Falls Out
There is a lot of well-meaning advice online about what to do when a crown falls out. Some of it is fine. Some of it can make things worse. Here is what to avoid.
Do not try to glue the crown back yourself using household adhesive like super glue. This is a mistake that dentists see more often than you might expect. Super glue is toxic, can permanently damage the crown, and makes it nearly impossible for the dentist to properly re-cement it later. Dental cement from a pharmacy is acceptable for very short-term use but that is as far as it should go.
Do not ignore it because it does not hurt. A fallen crown is not always painful right away, especially if the nerve is not exposed. But the lack of pain does not mean the tooth is protected. Damage can be happening silently.
Do not throw the crown away. Even if it looks damaged or old, bring it to your dentist. They can assess it and may still be able to use it, or at minimum it helps them understand the fit needed for a replacement.
When you come in for your appointment, bring the following:
- The crown itself, stored in a small bag or container
- Any notes on when it fell out and what you were eating at the time
- Information on any sensitivity or pain you have experienced since
- Your insurance card or payment information
