Your crown came off or chipped: what to do first, at home or while travelling

Crowns are fixed in place and are meant to stay there for years. Even so, a crown can come loose, or a corner of it can chip, often while you are eating something unremarkable. It tends to happen at the worst moment: a Friday night, the first day of a holiday, the week of a wedding. The good news is that very few crown problems are true emergencies. The steps below are what to do first, followed by what usually causes the problem and how to handle it if you are away from home.

In the first hour: if the crown has come off

Stop eating and find the crown. It may be in your food or on your plate. Once you have it:

• Rinse it gently under cool water and dry it. Keep it in a small clean container or a sealed bag. A pocket or tissue is how crowns get lost or thrown away.
• Rinse your mouth with warm water to clear food from the tooth.
• Look inside the crown. If there is a chunk of tooth in it, the tooth underneath has broken, which changes what the dentist will need to do. Tell them when you call.
• Look at the tooth in a mirror and take a photo. A dentist or your clinic can learn a surprising amount from a clear picture.

The tooth underneath may be sensitive to cold air, cold drinks and sweet things, because the prepared surface was never meant to be exposed. Keep it clean, chew on the other side, and avoid very hot, cold or sugary food for now. The NHS advice for toothache while you wait for a dentist is sensible here too: painkillers such as paracetamol or ibuprofen if you need them, a pain-relieving gel from a pharmacy, salt-water rinses, soft foods and a soft toothbrush.

What not to do

• Do not use superglue or any household adhesive. It is not made for the mouth, it can set the crown in the wrong position, and it makes the dentist's job harder.
• Do not force the crown back on. If it will not seat easily, it is not meant to go back without a dentist checking it.
• Do not leave it out for weeks. Teeth next to and opposite a gap can drift, and an uncovered tooth can decay or break further. A crown that fitted perfectly may not fit after a long delay.
• Do not throw it away, even if it looks damaged. It may be recementable, and it is useful evidence for working out why it came off.

Some pharmacies sell temporary dental cement. If the crown slides back on easily and your bite feels normal, a dentist may suggest using it to hold the crown until you are seen. Treat it as a short stopgap, not a repair, and follow the pack instructions carefully. If you have any doubt, leave the crown out and bring it to the appointment.

If the crown has chipped

Chips range from a tiny corner you only feel with your tongue to a break that exposes the core of the crown. In each case:

• Save any piece you find.
• If the edge is sharp and catching your tongue or cheek, a little sugar-free gum or orthodontic wax over it can protect the soft tissue until you are seen.
• Avoid biting on that crown, particularly hard or crunchy food.
• If you also knocked your face or mouth, follow the American Dental Association's advice for a cracked tooth: rinse with warm water and use a cold compress on the face to keep swelling down, then see a dentist.

What happens next depends on the size and location of the chip. A small chip can often be smoothed and polished. Some chips in porcelain can be repaired with a tooth-coloured filling material, which can last a while but is not as durable as the original surface. A larger fracture, or one where the porcelain has come away from a zirconia or metal core, usually means the crown needs to be replaced.

Why crowns come off or chip

Knowing the likely cause helps you and the dentist decide whether to recement, repair or replace.

Something has changed underneath

The most worrying reason a crown comes loose is decay at the edge, where the crown meets the tooth. As the tooth softens, the cement loses its grip. You may not have felt anything, especially if the tooth is root-filled. Our article on decay under a crown explains why this is easy to miss. A tooth can also fracture under a crown, which is why that piece of tooth inside the crown matters.

Not enough grip

A crown holds on partly because of the shape of the tooth it sits on. Short, worn or very tapered teeth give less grip, so the cement does more of the work.

The material and the cement

Different crown materials behave differently. A large systematic review of single crowns found that zirconia crowns had significantly more loss of retention than metal-ceramic crowns, and that zirconia crowns with a porcelain layer were more often lost because that layer fractured (Sailer et al., 2015). A companion review of bridges found the same pattern for zirconia bridges: higher rates of ceramic fracture and loss of retention than other types (Pjetursson et al., 2015). Those reviews include older generations of zirconia, and materials and cementing methods have moved on, but they explain why material choice is a real decision. Our pages on zirconia crowns and E-max crowns go into the differences.

Force

Biting hard objects is a classic cause of chips. The Oral Health Foundation advises against biting hard things such as ice to help a crown last, and the ADA adds popcorn kernels and hard sweets to that list. Grinding and clenching at night also add up, which is why grinders are often advised to wear a night guard.

If it happens while you are travelling

A loose crown on a beach holiday or a work trip is annoying rather than dangerous in most cases. Practical steps:

• Pack the basics if you travel often: a small container, a soft toothbrush, floss and a painkiller you know you can take. The ADA suggests keeping floss in a first aid kit for exactly this sort of thing.
• If you have pain, swelling or a sharp broken edge, see a local dentist rather than waiting until you are home. Ask them to protect the tooth and, if possible, to recement the original crown rather than make a new one.
• Ask for written notes, X-ray copies if taken, and receipts.
• If you have no pain and the tooth is intact, it is often reasonable to keep the crown safe and see a dentist when you get back. Be sensible with food in the meantime.
• Tell your own clinic as soon as you can.

If your crown came from us

Our crowns carry a 5-year written guarantee. Guarantee work is done at our clinic in Antalya: you pay your own flights, and we provide the hotel for the treatment period. Work by other dentists and your travel costs are not covered, and damage from contact sports or accidents is excluded. The guarantee may also be reduced or void if hygiene has been neglected, check-ups have been missed, or you grind and have not worn the night guard we advised.

So message us before anyone remakes the crown. If you need a local dentist to protect the tooth or temporarily recement the crown for comfort, do it; your health comes first. Then send us photos and any notes, and your coordinator will explain your options. Full terms are on our guarantee page, and our aftercare and longevity page covers check-ups and habits that make problems less likely.

Need a second pair of eyes?

If a crown has come off or chipped and you are not sure how worried to be, send us a photo through our contact page or on WhatsApp. We will tell you plainly whether it can wait, and what the realistic options are.

Common questions

Can I push my crown back on myself?

If it seats easily and you can bite normally, some dentists will suggest holding it in place with a temporary dental cement from a pharmacy until you are seen. Never use superglue or household adhesive, and do not force it. If you are not sure it fits, keep it in a container and bring it with you.

Is a crown coming off an emergency?

Usually it is urgent rather than an emergency. See a dentist within a few days. Get urgent help if you have swelling in your face or neck, severe pain that painkillers do not control, or difficulty swallowing or breathing.

Can a chipped crown be repaired?

Small chips can often be smoothed and polished. Some larger chips in porcelain can be repaired with tooth-coloured material, though that is usually a medium-term fix. A crown with a large fracture, or one that has broken through to the core, normally needs replacing.

My crown came off abroad. What should I do?

Keep the crown, protect the tooth, and find a local dentist if you have pain or a sharp edge. Keep receipts and notes. If the crown came from us, message us before anyone remakes it, because guarantee work is done at our clinic in Antalya. See our guarantee page.

Why do crowns come off?

Common reasons include decay or a broken tooth underneath, a short or tapered tooth giving little grip, and the cement breaking down at the edges over time. Studies also report loss of retention more often for some zirconia crowns than for metal-ceramic ones.
