My crown fell out: what to do

A crown coming loose or falling out is alarming, but it is rarely an emergency, and it is usually fixable. Knowing what to do calmly in the moment, and what not to do, protects the tooth and makes putting it right straightforward. This article is a practical guide for when a crown comes out, whether it happened today or you want to be prepared.

First, do not panic

A crown coming off is a common dental event, not a disaster. The tooth underneath is usually fine, and the crown can very often be re-fitted or replaced. Panic leads to rushed decisions like trying to glue it back with household adhesive, which can cause harm. The calm, correct steps are simple, and taking them protects both the tooth and the crown. Stay calm and deal with it methodically.

What to do straight away

If the crown has come out, retrieve it if you can and keep it safe, since it can often be re-cemented. Gently clean the tooth and the crown, avoiding any force. Keep the exposed tooth clean by brushing gently around it, and be careful eating, favouring the other side. If there is sensitivity, over-the-counter dental cement from a pharmacy can temporarily cover the tooth, but this is a stopgap, not a fix. The real solution is seeing a dentist.

What not to do

A few things make matters worse. Do not use household glue or superglue to reattach a crown, it is toxic in the mouth and can damage the tooth and crown, complicating proper repair. Do not ignore it and leave the tooth exposed for a long time, as the unprotected tooth is vulnerable. Do not chew on that side. And do not throw the crown away, even if it seems damaged, since your dentist needs to see it to judge whether it can be re-fitted.

Getting it fixed

The proper fix is a dentist re-cementing the existing crown if it and the tooth are sound, or making a new one if needed. This is usually a simple appointment. If your crown was fitted abroad, this is exactly where aftercare matters: our remote follow-up can quickly assess a photo and advise, and our UK partner network can arrange an in-person re-fit at one of eight UK locations if needed, rather than you having to fly back for a straightforward re-cementing. A real aftercare route turns this from a worry into a quick fix.

Why crowns come loose

Understanding why helps prevent a repeat. A crown may come loose because the cement has worn over time, because decay has formed under it weakening the bond, or because of a hard bite or trauma. If decay is the cause, simply re-cementing is not enough, the decay must be treated, which is why a proper dental assessment matters rather than a DIY reattachment. Good daily care and regular check-ups, as our caring for crowns article covers, reduce the chance of it happening.
