Lost Filling or Crown in Canberra: Cheap to Fix Now, Expensive to Leave
Keep the crown in a hard container. Never use superglue. The tooth starts moving within weeks.
A lost filling or crown at Dental Embassy in Braddon is usually a straightforward repair if it is dealt with promptly. Recementing an intact crown onto sound tooth is one of the least expensive things we do. Leaving it is what turns it into a rebuild.

Why it failed matters
Or it fails again
A filling or crown coming out is rarely painful and almost never dramatic, which is exactly why it gets postponed. It is also one of the clearest examples in dentistry of a small problem with a deadline attached.
Two things start happening immediately. The exposed dentine underneath is far softer than enamel and decays quickly. And the neighbouring teeth begin drifting toward the space, which within weeks can mean the crown you carefully kept no longer fits.
What to Do Today
If a crown came off, find it and keep it. Rinse it, dry it, and put it in a small hard container, not a tissue and not your pocket. Crowns are lost in bins and washing machines constantly, and a lost crown turns a quick recementation into making a new one at several times the cost.
Do not use superglue or any household adhesive. It is not biocompatible, it sets the crown in slightly the wrong position, and removing it afterwards can damage the crown or the tooth beyond repair. Pharmacy temporary dental cement is fine for a night or two if you genuinely cannot be seen.
Keep the area clean and brush it gently. Chew on the other side. Avoid very hot, very cold and sticky foods, and if a sharp edge is catching your tongue, sugar-free gum or orthodontic wax over it helps until your appointment. Then call 1300 000 230.
When It Is More Urgent
Most lost restorations are not emergencies. Some are.
Lingering pain to hot or cold, or pain on biting, suggests the nerve is involved and may need root canal treatment rather than a simple refill. Severe or spontaneous pain is covered on our toothache page, and any facial swelling means same-day: see dental abscess.
A lost front crown is also reasonably urgent, for entirely legitimate reasons that are about your week rather than your tooth. Tell us when you call and we will prioritise it.
Why It Came Out
This is the part most people skip and it decides whether it happens again.
Decay under the margin is the most common cause. The cement seal only holds against sound tooth, and once decay undermines the edge, the restoration loses its foundation. Simply cementing the crown back onto decayed tooth guarantees a repeat.
Fracture of the underlying tooth is next, particularly on teeth that have had root canal treatment, which are more brittle. If a piece of tooth came away with the crown, the tooth may need rebuilding before anything is refitted.
Cement failure over time genuinely does happen to well-made crowns after many years, and is the best of the possible answers because the fix is simply to recement it.
Grinding and clenching generate forces that shear restorations off. If you have lost several over a few years, the grinding is the actual diagnosis and a night splint is part of the treatment, otherwise we are just repeating the repair.
What the Appointment Involves
We examine the tooth and the restoration, and x-ray to check for decay and fracture under the margin.
If the crown is intact and the tooth is sound, we clean both and recement it, usually in a single visit. If there is decay, it is removed first and the tooth rebuilt to give the crown something solid to sit on. If the tooth has fractured or too little remains, a new crown or another approach may be needed, and where the tooth cannot be restored we will say so and talk through extraction and replacement rather than patching something that will fail.
A lost filling is generally replaced in one visit, unless the cavity has grown to the point where a crown is now the better answer. Our crowns and bridges page covers how that decision is made, and this guide covers holding the fort until you can be seen.
The Cost Argument for Coming In Early
Recementing an intact crown onto sound tooth is one of the cheapest appointments we offer. Replacing a filling is modest. Both stay that way only while nothing else has changed.
Add decay and you add its removal and a rebuild. Wait long enough for the tooth to shift and the crown no longer seats, so it has to be remade. Wait longer still and the nerve becomes involved, which means root canal treatment and then a crown. The same tooth can cost a small amount in week one and a great deal in month six, and nothing about it will hurt along the way to warn you.
We are preferred providers for HCF, nib and Defence Health, claim on the spot through HICAPS, and offer interest-free payment plans. See our fees page. If it has been years since your last visit, this page covers how we handle that, and if nerves are the reason, start at dental anxiety.
Common Questions
Frequently Asked Questions
Usually not, but it should not wait weeks either. Without pain it is an urgent-ish appointment rather than a same-day one. What does warrant same-day attention is lingering pain to hot or cold, pain on biting, a sharp edge cutting your tongue, or a lost crown on a front tooth where appearance matters to you.
Never with household adhesive. Superglue is not biocompatible, it sets the crown in the wrong position, and it makes proper recementation far harder or impossible, which can turn a simple refit into a remake. Pharmacy temporary cement is acceptable for a night or two if you cannot be seen immediately.
Rinse it, dry it, and keep it in a small hard container rather than a tissue or a pocket. Crowns go missing in bins and washing machines with remarkable regularity, and if the crown is lost the appointment changes from a recementation to making a new one, at several times the cost.
Rarely just bad luck. The usual reasons are decay under the margin that has undermined the cement seal, a fracture in the remaining tooth, cement that has washed out over years, or grinding forces. That matters because a crown that has come off once because of decay will come off again if the decay is not dealt with.
Not for long. Exposed dentine is much softer than enamel and decays quickly, and the neighbouring teeth start to drift toward the gap within weeks, which can mean the crown no longer fits when you do come in. A painless lost filling is a cheap problem that becomes an expensive one on a predictable timetable.
Not necessarily. Teeth prepared for a crown often look dark simply because the underlying dentine is exposed, or because the tooth has had root canal treatment. Dark and soft is a different matter and usually means decay. We will tell you which it is, and it does not change what you should do today either way.
Recementing an intact crown onto sound tooth is one of the least expensive things we do. Replacing a lost filling is modest. Costs rise when there is decay to remove first, when the remaining tooth needs rebuilding to hold the crown, or when the crown itself is lost or broken and has to be remade. That is why coming in early is a financial argument as much as a clinical one.
Recementing an existing crown usually is. A replacement filling usually is. A new crown involves preparation, an impression or scan, and a laboratory stage, so it takes two appointments with a temporary crown in between.
