Crown Came Off - What Should I Do?
If your dental crown has come off, try not to panic. Keep the crown safe, avoid chewing on that side, and arrange a dental assessment so the crown and tooth underneath can be checked.
This guide explains what to do straight away, what to avoid, whether it can wait if there is no pain, and when a lost crown may need urgent dental care.
If the tooth is very painful, broken, swollen, bleeding, traumatised, or you have facial swelling or fever, visit our emergency dentist in Brisbane page for urgent dental guidance.
Why this guide exists
Why does a crown coming off need a dental check?
A dental crown protects a tooth that may already be weakened, heavily filled, cracked, root canal treated, or structurally compromised. When the crown comes off, the tooth underneath may be exposed to chewing pressure, sensitivity, decay or further fracture.
This page helps you understand what to do if an existing crown falls off. It is an educational support guide and supports, rather than replaces, our main dental crowns page and dental crown cost guide.
Quick answer
My crown came off - what should I do first?
Keep the crown safe, avoid chewing on that side, gently clean the area, and contact a dentist for assessment. Do not use superglue or household glue to put the crown back on.
If the crown and the tooth underneath are still suitable, your dentist may be able to recement the crown. If there is decay, fracture, poor fit, pain, infection or not enough healthy tooth structure, other treatment may be needed.
Who this guide is for
Is this guide for me if my crown fell out?
This guide may help if an existing dental crown, cap or temporary crown has come loose or fallen off.
My crown came off but it does not hurt
Even without pain, the tooth underneath may be exposed and should be checked before the crown is recemented.
My crown fell out while eating
Keep the crown, avoid chewing on the tooth, and bring the crown to your appointment.
My tooth under the crown hurts
Pain can mean the tooth, nerve, gum, bite or remaining tooth structure needs assessment.
My temporary crown came off
A temporary crown protects the tooth while the final crown is being made, so it should be checked promptly.
Immediate steps
What should I do immediately if my dental crown comes off?
The most important step is to protect the crown and the tooth underneath until a dentist can check the area.
1. Keep the crown safe
Place the crown in a small bag or container. Bring it to your dental appointment so the dentist can check whether it may be reused.
2. Avoid chewing on that side
The exposed tooth may be weaker, sensitive or vulnerable to fracture. Try to chew on the other side until it is checked.
3. Keep the area clean
Brush gently and rinse with water. Avoid aggressive cleaning if the tooth or gum is sore.
Bring the crown with you
Even if the crown looks old, cracked or dirty, bring it to the appointment. Your dentist can check the inside of the crown, the tooth underneath and whether recementation is realistic.
What to avoid
What should I avoid if my crown has fallen off?
Some quick fixes can make the situation worse or make future treatment harder.
Do not use superglue
Household glue is not safe for dental use and can damage the crown, gum or tooth surface.
Do not chew on the exposed tooth
The tooth may fracture or become more sensitive if it is not protected.
Do not force the crown back on
If the crown does not seat properly, biting on it may damage the tooth or crown.
Do not ignore it because there is no pain
A crown can come off without pain, but the tooth underneath may still be at risk.
No pain
My crown fell off but it does not hurt - can I wait?
If there is no pain, swelling or trauma, it may not always be a medical emergency. However, it is still worth arranging a dental assessment because the exposed tooth may be more vulnerable to decay, sensitivity, food trapping or fracture.
| What you notice | What it may mean | What to do next |
|---|---|---|
| Crown came off but no pain | The tooth may still need protection and assessment. | Keep the crown safe and arrange a dental check. |
| Tooth is sensitive to air or cold | The tooth surface may be exposed. | Avoid chewing there and contact your dentist. |
| Crown keeps coming off repeatedly | The fit, cement seal, bite or tooth shape may no longer be predictable. | A more detailed review may be needed. |
| Tooth underneath looks dark, soft or broken | Decay, fracture or loss of tooth structure may be present. | Arrange assessment before recementation is attempted. |
Urgent warning signs
When is a crown coming off urgent?
A crown coming off can become more urgent when the tooth is painful, broken, infected, swollen, traumatised, or difficult to use. If you are unsure, it is safer to call for advice.
Recementation
Can the same crown be recemented?
In some cases, yes. A crown may be recemented if the crown still fits well, the tooth underneath is healthy enough, there is no significant decay or fracture, and the bite is suitable.
Recementation may not be suitable if the crown no longer fits, the tooth underneath is soft or decayed, there is not enough tooth structure remaining, the crown is cracked, or the tooth has symptoms that need further investigation.
Recementation may be possible if
- The crown still fits the tooth properly.
- The tooth underneath is still strong enough.
- There is no active decay or major fracture.
- The bite does not place excessive pressure on the crown.
A new plan may be needed if
- The tooth has decayed or broken underneath.
- The crown no longer seats properly.
- The tooth is painful, infected or has poor prognosis.
- The crown repeatedly comes off.
Fee guidance
How much does it cost to recement a crown?
Recementing a crown is different from making a new crown. The fee depends on whether the crown and tooth are suitable, whether X-rays are needed, and whether any other treatment is required.
Approximate recementation estimate
If the crown and the tooth underneath are still in good condition, recementing the crown may cost approximately $300-$500, including an examination and any required X-ray. This estimate applies only when no other treatment is needed and the crown can be safely recemented.
If there is decay, fracture, pain, infection, poor crown fit, or not enough healthy tooth structure remaining, recementing may not be suitable. In that case, your dentist may discuss other options, such as repairing the tooth, replacing the crown, root canal treatment, or removal if the tooth has a poor prognosis.
It is also important to understand that a crown that has come off once may have a higher chance of coming off again. The reason may be loss of cement seal, a change in the tooth underneath, decay, bite pressure, or the crown no longer fitting the tooth as well as it once did.
If a replacement crown is needed, see our dental crown cost guide. If you would like to understand available finance options, see our payment plan options.
Core explanation
What might be happening to the tooth under the crown?
When a crown comes off, the most important question is not only whether the crown can go back on. The dentist also needs to check why it came off and whether the tooth underneath is still suitable.
The cement seal may have failed
Sometimes the crown loses its seal even if the tooth is still mostly intact.
Decay may be present
Decay can develop under or around a crown, especially if the seal has been leaking.
The tooth may have fractured
If the remaining tooth has cracked or broken, recementing the same crown may not be appropriate.
The bite may be placing pressure on it
Heavy bite pressure or grinding may contribute to a crown loosening or coming off.
What patients often notice
What do people often notice when a crown comes off?
Patients often describe a crown coming off in simple, practical ways. These details can help your dentist understand the situation.
“It came off while eating”
This may happen when the cement seal weakens or the crown is placed under chewing force.
“The tooth underneath feels sensitive”
The tooth may be exposed to air, temperature or chewing pressure.
“It does not hurt, but it looks strange”
No pain does not always mean the tooth is safe to leave uncovered.
Decision block
Do I need recementation, a new crown, or another treatment?
The right next step depends on the crown, the tooth underneath, symptoms, X-ray findings and long-term prognosis.
| Situation | Possible next step | Why assessment matters |
|---|---|---|
| Crown fits well and tooth is sound | Recementation may be possible. | The dentist must confirm fit, seal and bite. |
| Tooth has decay under the crown | Repair, new crown or other treatment may be needed. | Cementing over decay is not appropriate. |
| Tooth is cracked or broken | A new crown, core repair, root canal review or extraction may be discussed. | The tooth must be restorable enough to hold a crown. |
| Pain, swelling or infection signs | Urgent assessment may be needed. | The nerve or surrounding tissues may be involved. |
What we commonly see
What do we commonly see when a crown comes off?
At EasyCare Family Dental, a crown coming off is not treated as “just glue it back on” until the tooth is checked. The most important step is to understand why it came off and whether the crown can still predictably protect the tooth.
Sometimes the crown can be recemented. Other times, the tooth underneath has changed, the crown no longer fits, or the remaining tooth structure needs a different plan.
A crown that looks reusable
The crown may look fine, but the tooth underneath still needs checking.
A tooth that has changed shape
Decay, fracture or loss of cement seal can change how well the crown fits.
A patient who has no pain
Even without pain, the uncovered tooth may be more vulnerable.

FAQ
FAQs about a crown coming off
These answers are general and are designed to help you decide when a crown and tooth should be professionally assessed.
My crown came off - what should I do?
Keep the crown safe, avoid chewing on that side, keep the area clean, and arrange a dental check. Bring the crown to your appointment so the dentist can check whether it may be recemented.
My crown fell off but it does not hurt - can I wait?
If there is no pain, swelling or trauma, it may not always be a medical emergency. However, the tooth underneath may still be exposed and should be checked before it fractures, decays or becomes sensitive.
Can I glue my crown back on at home?
Do not use superglue or household glue. These products are not safe for dental use and can damage the crown, gum or tooth surface.
Can the same crown be recemented?
Sometimes. The same crown may be recemented if it still fits well and the tooth underneath is suitable. If there is decay, fracture, poor fit or pain, other treatment may be needed.
How much does it cost to recement a crown?
If the crown and tooth underneath are suitable, recementing a crown may cost approximately $300-$500, including examination and any required X-ray, when no other treatment is needed.
Can a crown come off again after recementation?
Yes, it can. Once a crown has come off, the cement seal, crown fit, bite or tooth structure underneath may have changed, which can increase the chance of it coming off again.
What if the tooth underneath my crown is black or broken?
A dark, soft or broken tooth underneath a crown may suggest decay, staining, fracture or loss of tooth structure. The dentist needs to assess whether the tooth can still support a crown.
Is a crown coming off a dental emergency?
It may be urgent if there is severe pain, swelling, trauma, bleeding, facial swelling, fever or a broken tooth underneath. If there is no pain, it should still be checked soon because the tooth may be exposed.
What should I do if my temporary crown came off?
Keep the temporary crown safe, avoid chewing on the tooth, and call your dentist. A temporary crown protects the prepared tooth while the final crown is being made.
