The temptation is to press it back on and carry on with the day. If you are coming from Oakville with a crown that has let go, we first find out why, then tell you honestly whether that crown should be refitted.
It looks so simple. The crown is in one piece, the tooth is right there, and it seems like a dab of something sticky would solve it. In practice, a crown pushed back on at home can trap food or bacteria underneath, sit slightly high, or hide the reason it came off.
Professional recementation starts by asking whether the crown should go back at all. The dentist checks that it still fits, that the tooth below has not decayed or cracked, and that the surfaces can be properly cleaned and prepared. Only then is a dental cement chosen that suits that particular restoration.
So the most helpful thing you can do is keep the crown safe and call. Let us know how it came off, whether it had been loose and whether this is the first time. From Oakville, it is worth asking for a time that allows a full assessment, so you are not left guessing afterwards.
There may be no pain at all, and that is still worth a call. The team will want to know if the crown is fully detached, whether something seems stuck inside and what the tooth feels like now.
Store the crown in a clean pill box or small container and bring it in. Say what you were biting into and whether there had been any rocking beforehand. Avoid wedging it back onto the tooth or chewing on that side to test it.
Pay attention to what triggers it and how long it lasts. A tooth without its cover can be more reactive, and its condition has to be checked directly rather than assumed to be fine once the crown is back.
When the same crown keeps coming loose, the tooth, the crown and your bite all deserve a closer look. Share when it was last put back and whether a particular food or habit seems to set it off.
Still hanging on but moving? Leave it be and call for advice. Mention pain, swelling or a recent bump to the mouth when you book.
If the crown is undamaged and seats accurately on a tooth that can still support it, recementation may be a practical choice. It can save making a new crown when one is not needed. That judgment comes from examining both parts, not from how the crown looks in your hand.
A crown fixed onto a tooth that is no longer suitable tends to come back as the same problem later. If you are advised against reuse, ask what the dentist found. The answer should describe the tooth today, rather than resting on the crown’s age.
With a good fit and a sound tooth underneath, the existing crown may continue to cover and protect it. Ask whether any preparation or repair is needed before it is reattached.
An examination can reveal issues that a home repair would cover up. Ask what most likely caused it and how the plan responds.
Occasionally the crown is refitted to protect the tooth while other treatment is planned. Ask whether this is the finished result or a temporary step.
Whether the crown is reused depends on what the examination shows. Allow time to hear and discuss the findings, since the visit may point to a different treatment.
The dentist looks at the crown, the exposed tooth and anything inside the crown. Your symptoms and past treatment guide whether an X-ray or other tests are needed before deciding.
Fit, damage and the amount of support are reviewed. If decay or a fracture alters the advice, you will hear what that means, what else could be done and the costs involved.
Provided the crown is suitable, the tooth and crown surfaces are cleaned and readied, then a dental cement or bonding material matched to the restoration is applied. This is exactly the step that household products cannot replicate.
Position, contact with the neighbouring teeth and your bite are checked, and leftover cement is cleared. Ask about eating, cleaning and whether you need to come back.
Aftercare depends on the cement used, the tooth and what else was done. Before leaving, make sure the guidance is clear, especially when the refit is a temporary measure or you are still frozen.
Follow the eating timeline and food precautions from your dentist. Advice you received for a different crown may not apply. While frozen, chew carefully so you do not bite your cheek or tongue.
Use the cleaning approach recommended for that tooth. If floss shreds or catches, the gum gets sore or the surface feels different, let the team know instead of digging at it.
Should the crown loosen again or seem to land before your other teeth, it should be checked. Call to describe the change, and try not to keep testing it.

A crown can look perfect while the tooth under it has changed. These answers explain why an examination comes before cement.
Get in touch with our Bronte Street practice about a crown that is loose or has come off. Bring the crown along so we can assess it with the tooth, explain what we find and recommend a suitable way to protect the tooth.
If your crown is moving, the pain is severe, you notice swelling or you have had an injury, please call so the team can talk through timing and the right next step.
