Root canal temporary filling fell out? Ring the same day
An open canal lets saliva back into the cleaned tooth, even if nothing hurts. Have it sealed within one to two days; do not pack the hole with cotton wool.

If the temporary filling has fallen out of a tooth partway through root canal treatment, contact a dentist today and aim to have the tooth sealed again within one to two days, whether it hurts or not. Most of the time a tooth that has lost its temporary does not hurt, and that is exactly what persuades people to leave it. If only part of the filling seems to have gone and you cannot tell how much, treat it as the whole thing until a dentist has looked.
The reason is not the hole you can feel with your tongue. It is what the hole leads to.
What the temporary filling is holding in, and out
Root canal treatment removes the infected or inflamed pulp from inside the tooth, cleans and shapes the canals, and eventually seals them so that bacteria cannot get back in. Between visits, the canals usually hold a medicated dressing, and the temporary filling on top has two jobs: keeping that dressing where it is, and keeping saliva out. Saliva carries the bacteria that caused the problem in the first place. With the temporary gone, the canal entrance is open to it, and every day it stays open, the chance of the cleaned canals being recontaminated goes up. At best, the dentist has to wash the canals out again and replace the dressing, which may add a visit. If the canal is left open for a long time, the long-term success of the treatment can suffer. None of that shows up as pain in the first few days, which is why the absence of pain tells you very little. Root canal treatment abroad explains why the seal on top matters as much as the cleaning below.
All of it, or part of it?
| What you notice | What it probably means | How soon |
|---|---|---|
| The filling has gone and there is a hole in the middle of the tooth | The canal is open to the mouth | Ring the same day; sealed within one to two days |
| A piece has broken off, leaving a pit | The seal may be broken | Seen within a few days |
| The surface feels rough or slightly worn | Normal wear of a soft temporary material | Mention it at your next visit |
If you cannot tell which it is, assume the whole filling has gone.
Until someone can seal it
- Do not pack the hole with cotton wool, bread, chewing gum, wax or glue. Each of these carries bacteria into the canal and makes it harder to clean properly.
- Chew on the other side. A tooth partway through root canal treatment has lost a lot of its internal structure and can crack under a hard bite, and a crack can end the chance of saving it.
- Rinse gently with lukewarm water after eating, and carry on brushing the area softly.
- Leave the hole alone: no toothpicks, no fingers.
Temporary filling kits sold in pharmacies are designed for a lost filling on an ordinary tooth. On a tooth with an open canal they are, at most, a stopgap on the way to a dentist, not a replacement for one. If you need pain relief, ask a pharmacist or your dentist what suits you.
The symptoms that change the timetable
Some signs mean the tooth needs to be seen today, not in a day or two:
- noticeable swelling of the gum or face
- a raised temperature
- throbbing pain that gets worse when you bite
- pain that wakes you at night
If your practice is closed, in England NHS 111 can direct you to urgent dental care, and you do not need to be registered with an NHS dentist to use it; Scotland and Wales have their own equivalents. What happens out of hours goes through the options.
Swelling that spreads towards the eye or down the neck or grows by the hour, swelling under the tongue, or a high temperature or difficulty swallowing alongside the swelling is not a dental appointment: go to A&E (an emergency department in Ireland, a hospital acil servis in Turkey). If breathing becomes difficult, or someone becomes drowsy or confused, call 999 (112 or 999 in Ireland, 112 in Turkey) and do not make your own way there.
When the second visit is in another country
This happens most often to people whose root canal was started on one trip and is due to be finished on the next, or who left Turkey with the tooth under a temporary because the timetable ran out. Temporary fillings are designed to last weeks, not months, and the gap between trips is often longer than planned. A filling that has been in place for six weeks, through a flight and a lot of chewing, is exactly the one that comes out.
A dentist at home can usually clean the canal entrance and put in a new temporary seal without taking over the treatment. That is a short appointment, and it is a far easier request than asking them to finish the root canal. They will want to know what was done, when and on which tooth, so the records matter: a copy of the radiograph and the treatment notes, or at minimum a message from the clinic confirming the tooth and the stage. If you need a second trip deals with keeping that gap short, and keeping your own dentist in the loop with arranging help before you need it.
Tell the clinic abroad as well, with a photograph and the date. If the tooth later needs more work than expected, the timeline of when it was open and who resealed it is part of the answer, and it is much easier to establish on the day than months later.
A plan that leaves a root-filled tooth under a temporary for longer than a couple of months, with no named dentist to seal it, is a plan with a gap in it. That is worth raising before the first trip, not after the filling has gone.
