One second, you’re enjoying lunch—and the next, you feel something hard, strange, and unsettling rolling around in your mouth. A quick check in the mirror confirms it: your filling has fallen out. It’s one of those dental surprises that can catch anyone off guard. Is it serious? Should you rush to the dentist? Will it hurt? If you’ve just lost a filling or want to be prepared in case it happens, this guide will walk you through exactly what to do, when it’s an emergency, and how your dentist can help fix it.
What Causes a Filling to Fall Out?
Fillings are made to last, but they’re not indestructible. Over time or under certain conditions, they can loosen or break. Here’s why it might happen:
- Tooth decay under the filling – New decay can develop beneath the filling, weakening the support.
- Chewing hard or sticky foods – Things like toffee, nuts or crunchy snacks can loosen a filling.
- Teeth grinding or clenching – Constant pressure wears down the tooth and the filling.
- Age of the filling – Older fillings may crack or fall out as they wear over time.
- Accidental trauma – A knock to the jaw or biting something hard unexpectedly can dislodge a filling.
Should You Worry If a Filling Falls Out?
Not every lost filling is a dental emergency, but some situations do need urgent care. These symptoms should prompt you to call your dentist straight away:
- Sharp or throbbing pain
- Temperature sensitivity (hot, cold or sweet)
- A jagged edge cutting your tongue or cheek
- A visible hole in the tooth
- Swelling or signs of infection
Even if there’s no pain, the exposed area is more vulnerable to bacteria and further damage. It’s always best to get it looked at quickly.
What Should You Do Immediately?
If your filling falls out, acting quickly can prevent complications and make your dentist’s job easier. Here’s a simple guide to protect your tooth while you wait:
| What To Do | Why It Helps |
| Rinse your mouth with warm salty water | Helps keep the area clean and reduce bacteria |
| Avoid chewing on the affected side | Prevents more damage and pain |
| Apply dental wax or temporary material | Covers the hole and protects exposed nerves |
| Take pain relief if necessary | Manages discomfort until you get to the dentist |
| Contact your dentist | Book a professional appointment without delay |
These steps won’t fix the problem but can provide some short-term comfort.
What Will the Dentist Do?
Treatment depends on how badly the tooth is damaged and how long the filling has been missing. Your dentist will assess the situation and recommend the most suitable option.
| Treatment Option | When It’s Needed |
| New filling | If the tooth structure is mostly intact |
| Inlay or onlay | When there’s moderate damage to the tooth surface |
| Dental crown | For large breaks or structural weakness |
| Root canal therapy | If the nerve has been exposed or is infected |
| Extraction | Only used when the tooth can’t be saved |
Quick action can often mean a simpler, less invasive treatment.
What Types of Fillings Are Commonly Replaced?
Different fillings last for different lengths of time, depending on the material and where in the mouth they’re used. Here’s a breakdown:
| Filling Type | Material | Typical Lifespan | Common Failure Causes |
| Composite Resin | Tooth-coloured plastic | 5–7 years | Bonding failure, wear, or decay |
| Amalgam | Silver metal alloy | 10–15 years | Cracks, corrosion, or fracture |
| Gold | Gold alloy | 15–30 years | Loosening over time (rare) |
| Ceramic | Porcelain | 10–15 years | Chipping under pressure from grinding |
| Glass Ionomer | Acrylic and fluoride | 3–5 years | Shorter lifespan, wears more easily |
Knowing what kind of filling you had can help predict what might happen next.
What Happens If You Ignore It?
Putting off treatment might seem harmless, especially if the tooth doesn’t hurt. But here’s what can happen if you leave a lost filling untreated:
- Tooth decay can return – The hole acts as a trap for food and bacteria.
- The tooth may crack or break – Especially under pressure when eating.
- The nerve may become exposed – This can lead to severe pain and infection.
- You may need more complex treatment – Like a root canal or crown instead of a simple filling.
Even if there’s no immediate discomfort, it’s worth addressing the issue sooner rather than later.
When Should You See a Dentist?
The short answer is: as soon as possible. You don’t need to panic, but you shouldn’t wait too long either—especially if:
- The tooth is painful or sensitive
- You feel a sharp edge inside your mouth
- The tooth looks hollow or visibly damaged
- You’re having trouble eating normally
- The area seems to be swelling or bleeding
Early treatment can often mean a quicker and easier fix.

Important FAQs
Q1: Is losing a filling an emergency?
It depends. If there’s pain, sensitivity, or visible damage, you should see a dentist as soon as possible. Even if it doesn’t hurt, it’s still best to get it checked quickly.
Q2: Can I eat after my filling falls out?
Stick to soft, lukewarm foods and avoid chewing on the affected side until your dentist can restore the tooth.
Q3: Will the tooth always need a crown or root canal?
Not necessarily. Many teeth can be fixed with a new filling. But if there’s deeper damage or infection, more extensive treatment might be needed.
Q4: What happens if I don’t replace the filling?
Without protection, the tooth is at risk for decay, breakage, and infection. Early treatment is always better.
Q5: Can I use something at home to cover the hole?
You can use temporary dental wax or material from the pharmacy, but this is only a short-term solution. It’s not a substitute for proper dental care.
Q6: How long does it take to replace a filling?
In most cases, it takes 20 to 45 minutes. If more work is needed—like a crown or root canal—your dentist will let you know what to expect.
