— What this is
Lost filling or crown: what you need to know
A lost filling or crown is rarely a same-day emergency — but it does need attention within a few days. The exposed underlying tooth is more vulnerable to decay, fracture, and sensitivity. Without the protection of the restoration, food packs into the cavity, bacteria multiply, and the tooth weakens further. A repair that would have been straightforward at week one can become a root canal or extraction by month two if the cavity grows or the remaining walls of the tooth crack.
For lost crowns specifically: keep the crown if you have it. The matched dentist can almost always re-cement it back into place at a single appointment, which is cheaper than a brand-new crown. Pharmacy temporary cement (Recapit or similar) holds a crown in place for a few days until you can be seen. Clean both the inside of the crown and the underlying tooth gently before re-cementing, and avoid biting hard food on it.
Lost fillings vary by what was filling. A small composite repair from a routine appointment can usually be replaced like-for-like. A large amalgam filling (silver-coloured, mercury-based) that has held a tooth together for two decades may have been the only thing preserving structural integrity — its loss often signals a tooth that needs more than another filling, often a crown or even extraction. Matched dentists assess the remaining structure honestly rather than just patching.
— Why specialist matching matters
What good emergency care looks like for lost filling or crown
Re-cement existing crown at low cost
A lost crown that you have kept can usually be re-cemented at the appointment for a fraction of a new crown's cost. Bring the crown — clean it gently first.
Honest assessment of remaining tooth
Sometimes a lost large filling reveals a tooth that needs more than a simple repair. Matched dentists tell you when a crown or extraction is the right answer, with cost comparison — rather than just patching for short-term convenience.
Temporary protection guidance
If you cannot be seen for 24–48 hours, the matched dentist advises on pharmacy temporary cement, dietary precautions, and any pain-management steps that prevent the situation worsening.
No upsell pressure
A simple re-cement or filling replacement should be quoted at simple-procedure rates. Matched dentists do not use the emergency context to push expensive treatment that is not clinically justified.
— Common mistakes
Three mistakes with lost fillings and crowns
1. Throwing away a lost crown
A lost crown that you have kept can usually be re-cemented for a fraction of the cost of a new crown. Clean it gently and store it somewhere safe — bring it to the appointment.
2. Ignoring it because there is no pain
Painless lost fillings still leave the underlying tooth vulnerable to decay, fracture, and food packing. A simple replacement at week one becomes a more complex restoration by month three.
3. Using superglue or household adhesive to re-attach
Superglue is toxic to dental pulp and produces a damaged surface that proper dental cement cannot bond to afterwards. Pharmacy temporary cement (Recapit or similar) is the only safe DIY option.

Severe toothache
A lost filling that has been ignored for a few weeks often progresses to severe toothache as decay reaches the pulp. Earlier intervention prevents this trajectory.

Is matching for lost filling or crown right for you?
Same-week matching for lost fillings or crowns is right if:
- A filling has fallen out and you have noticeable sensitivity or food packing in the cavity
- A crown has come off — even without pain, the underlying tooth is vulnerable
- You can feel a sharp edge on the broken tooth that is irritating your tongue or cheek
- A temporary filling placed at a previous appointment has come out before the permanent restoration was done
- You are about to travel and want the tooth secured before going abroad
— The matching process
How lost filling or crown matching works
Locate the lost piece if possible
For a lost crown, find it — most can be re-cemented if intact. For a lost filling, the original material is not re-used (a fresh restoration is placed) but knowing what was there helps the dentist.
Use pharmacy temporary cement if needed
If you cannot be seen for a day or two, Recapit-style temporary cement from any pharmacy holds the crown in place. Avoid biting on it.
Submit the matching form
We match within the working day for genuine sensitivity or pain, or within 48 hours for asymptomatic cases.
Re-cementation or replacement
Most cases are resolved at a single appointment — the existing crown re-cemented or a fresh filling placed. Where the underlying tooth is too damaged for simple repair, the dentist discusses the longer-term options.
This is a dental matching service, not a medical service
For genuine medical emergencies — uncontrolled bleeding, facial swelling spreading to your eye, throat or neck, difficulty breathing or swallowing, or feeling severely unwell — these are hospital problems and need IV antibiotics, not a dental appointment.
