Why Fillings Fall Out
Fillings can last for years, but they’re not permanent. Here are some common reasons they might come loose:
- Wear and Tear: Constant chewing, grinding, or biting into hard foods can weaken the bond.
- Decay Under the Filling: If bacteria sneak in beneath the filling, decay can loosen its grip.
- Trauma: A blow to the mouth or biting down too hard can dislodge a filling.
- Old Age: Materials like composite or amalgam naturally degrade over time.
What You Might Notice
When a filling falls out, you may experience:
- Sensitivity to hot, cold or sweet foods
- A sharp or rough edge on the tooth
- Pain when chewing or applying pressure
- A visible hole or gap in the tooth
- A piece of the filling in your mouth
Some people feel no pain at all—but even if it doesn’t hurt, it still needs attention.
Step-by-Step: What to Do if Your Filling Comes Out
1. Stay Calm
It’s common and fixable. Take a breath.
2. Remove the Filling (If It’s Still in Your Mouth)
Spit it out or gently remove it to avoid swallowing or inhaling it.
3. Rinse Your Mouth
Use warm salt water to gently clean the area. This helps prevent infection and removes debris.
4. Avoid Chewing on That Side
Stick to soft foods and avoid biting down on the affected tooth until you’ve seen your dentist.
5. Manage Sensitivity or Pain
Over-the-counter pain relief and temporary dental wax (available at chemists) can help reduce discomfort.
6. Book an Appointment as Soon as Possible
Even if you’re not in pain, your tooth is now exposed and vulnerable. Waiting can lead to more extensive treatment or infection.
What Your Dentist Will Do
At your appointment, your dentist will:
- Examine the tooth and take X-rays to assess damage
- Remove any remaining decay or loose material
- Decide on the best restoration—this may be a new filling, or a crown if the tooth has weakened
- Restore the tooth so you can get back to eating, speaking, and smiling comfortably
Can You Leave a Lost Filling Untreated?
Short answer: it’s not worth the risk.
An exposed tooth is a magnet for bacteria, which can lead to:
- Tooth sensitivity or pain
- Further decay
- Infection or abscess
- Breakage or cracking
- The need for a more complex procedure, like a crown or root canal
The sooner it’s fixed, the less likely you are to need additional treatment.
Temporary Solutions (If You Can’t See the Dentist Right Away)
If you’re travelling or can’t get to the dentist right away:
- Apply temporary filling material (available at most pharmacies)
- Use orthodontic wax to cover sharp edges
- Stick to lukewarm, soft foods
- Keep the area clean, brushing gently around the exposed tooth
But remember—these are short-term fixes only. Book your appointment as soon as possible.
Prevention Tips: How to Avoid Losing a Filling Again
- Don’t bite down on hard or sticky foods (like ice, toffee, or nuts)
- Brush and floss daily to prevent decay around the filling
- Visit your dentist regularly to check the integrity of your fillings
- Use a mouthguard if you grind your teeth at night
