A lost filling isn’t just annoying — it can quickly turn into a dental emergency. If your tooth starts hurting after the filling falls out, don’t wait. Let’s break down what causes fillings to come loose, how to spot a problem early, and what to do before you see your dentist.
At True Smile Dental Centre in Abu Dhabi, our friendly dentists treat these situations every day — and we’re ready to help.
Why Do Fillings Fall Out?
There are many reasons a filling might come loose. Some are out of your control, but others are warning signs your tooth is asking for help.
- New decay under the filling.
Sometimes bacteria sneak in under an old filling, leading to decay (this is called secondary caries). The filling may loosen or fall out as a result. - Biting something hard.
Crunching ice, chewing pens, or biting your nails can crack or pop out a filling — especially if it was already weakening. - Grinding your teeth.
If you grind your teeth at night (bruxism), it puts constant pressure on your fillings. They can loosen over time. - The filling got old.
Like anything else, fillings wear out. Composite (white) fillings last around 5–7 years, and metal ones up to 10. After that, they can crack or fall out. - Moisture during treatment.
If the area wasn’t dry enough during the procedure, the filling might not have bonded well. At True Smile Dental Centre, we always use professional isolation techniques like rubber dams to make sure fillings stay in place for years.
Signs a Filling Might Be in Trouble
Don’t wait for a filling to fall out — your tooth will usually give you some warning first. Look for:
1. Sensitivity to hot, cold, sweet, or sour
This could mean the filling isn’t sealed properly anymore, and your tooth’s inner layer (dentin) is exposed.
2. Rough edges or visible cracks
Run your tongue over the filling. Feel a sharp spot or see discoloration? It may be time to replace it.
3. Loose or wiggling filling
Even a little movement is a red flag. Book a visit right away.
4. Bad breath or odd taste
Bacteria hiding under a loose filling can cause an unpleasant smell or taste in your mouth.
5. Pain when you chew
If biting down hurts, it might be due to a cracked filling or pressure on exposed nerves.
What to Do Before You Visit the Dentist
If your filling falls out and your tooth is hurting, here’s how to stay comfortable until your appointment:
- Rinse with warm saltwater or an antiseptic mouthwash.
- Try not to chew on the affected side. Stick to soft food.
- Take an over-the-counter pain reliever like ibuprofen or paracetamol.
- Avoid hot, cold, or sugary foods.

Special Cases: What If…
…the filling fell out of a root canal treated tooth?
That’s more serious. These teeth are more fragile and can break easily. Don’t wait — visit us as soon as you can. You’ll likely need a new filling or crown to protect the tooth.
…the temporary filling fell out?
That’s common — they’re not made to last long. But it still needs replacing quickly, as the tooth underneath is often in the middle of treatment.
…you can’t get to the dentist right away?
Here’s a quick guide:
| Tooth Type | Max Time Without Filling | Risk |
| Front tooth | 1–2 days | High |
| Molar (back tooth) | Up to 3 days | Moderate |
| Root canal tooth | No more than 1 day | Very High |
Remember: the longer you wait, the higher the chance of complications — including infection, nerve damage, or needing a root canal.
What NOT to Do
- Don’t try to glue the filling back in yourself.
- Don’t ignore the pain — it could mean something serious.
- Don’t put aspirin or painkillers directly on the tooth (it can burn your gums!).
What Kind of Fillings Last the Longest?
| Filling Type | Lifespan | Pros | Cons |
| Composite (white) | 5–7 years | Looks natural, strong | Wears over time |
| Glass ionomer | 3–5 years | Gentle, releases fluoride | Less durable |
At True Smile Dental Centre in Abu Dhabi, we use high-quality composite materials. They’re durable, safe, and designed to look just like your natural tooth. Our dentists make sure your new filling fits perfectly, feels comfortable, and stays in place for years.
Final Tip: Don’t Wait
A missing filling can lead to infection, broken teeth, and much more costly treatment later. Whether you’re in pain or just noticed something loose — the best step is to come in.
