Tooth Pain
A filling fell out. What now?
5 July 2026 · The Dentist, Al Qusais, Dubai
The short answer
If a filling falls out, the tooth underneath is exposed and vulnerable, so keep the area clean, avoid chewing on that side, and see a dentist within a few days even if it doesn't hurt yet. Save the piece if you find it, but don't try to glue it back yourself. If there's sharp pain, sensitivity to hot or cold, or a visible hole, book an appointment sooner rather than later, because the tooth can decay quickly once the filling material is gone.
Why it matters more than it feels like it does
A filling isn't just a cosmetic patch. It's sealing a hole that was drilled to remove decay, and once it's gone, that hole is open again. Bacteria, food debris and saliva can get straight into the dentine underneath, which is softer and more sensitive than the enamel around it. Some people feel nothing at all when a filling drops out. Others get an immediate jolt of sensitivity to cold drinks or sweet food, because the nerve is suddenly much closer to the surface.
The risk isn't usually that the tooth will fall apart overnight. It's that decay restarts in a spot that's already had one filling, and old fillings often sit over teeth that had a fair amount of structure removed the first time round. Left too long, a simple refill can turn into a bigger job: a crown, or in worse cases a root canal. That's the main reason to treat this as a "see a dentist this week" situation rather than a "wait until it hurts" one.
What to do in the first 24 to 48 hours
Rinse gently with warm water to clear out any food that's got into the gap, but don't scrub at it or poke around with a sharp object. Chew on the other side of your mouth for now. If the edges of the tooth feel sharp against your tongue or cheek, a small piece of sugar-free chewing gum pressed gently over the hole (not chewed, just placed) can act as a temporary barrier, and pharmacies also sell temporary filling material for exactly this purpose. It's not a fix, but it can reduce sensitivity and stop food packing into the space for a day or two.
If you found the actual filling piece, keep it and bring it with you, it sometimes helps the dentist see what material and shape was there before. Avoid very hot, very cold or very sugary food and drink on that side, since these are what tend to trigger discomfort. Over-the-counter pain relief such as paracetamol or ibuprofen is fine if there's soreness, following the packet dosing.
What you shouldn't do is try to repair it yourself with superglue, wax, or anything not designed for teeth. It won't bond properly, it can trap bacteria against the tooth, and it makes the dentist's job harder when they do see you.
When it's urgent versus when it can wait a few days
A dull ache, mild sensitivity, or a visible gap with no pain can usually wait for a routine appointment within the week. Genuine urgency looks different: throbbing pain that keeps you up at night, swelling in the gum or face, a bad taste that won't go away, or pain when you bite down hard. Those signs point to infection or a crack reaching deeper into the tooth, and that needs same-week attention, sometimes same-day.
