If you’ve ever had a temporary filling fall out, you know how alarming it can feel. Suddenly, you’re left with an open tooth that feels sensitive, and you might not be sure what to do next. The truth is, while losing a dental filling isn’t unusual, it does require quick attention to keep your tooth protected until you can see your dentist.
A temporary filling is exactly what it sounds like: a short-term dental restoration placed to protect your tooth until your permanent filling or dental crown is ready. Dentists often use temporary fillings after treating a cavity, during root canal therapy, or while waiting for a custom crown to be made.
In this guide, you’ll learn what a temporary filling is, why it sometimes falls out, the immediate steps you should take at home, and when it’s time to call your emergency dentist. Keep reading, you’ll feel much more confident knowing exactly how to handle this situation.
Immediate Steps to Take When You Lose a Temporary Filling
So, your temporary filling just fell out. What now? The good news is, there are safe, simple things you can do at home to protect your tooth until your dentist replaces it.
Quick Reference Table: Temporary Filling Care at Home
| What to Do | How to Do It |
|---|---|
| Protect the Tooth | Avoid chewing on it, and use dental cement if possible |
| Reduce Pain & Sensitivity | Take pain relief, rinse with salt water, and avoid hot/cold/sweet foods |
Inspect the Tooth Carefully
First, take a moment to check the tooth in a mirror. Make sure no pieces of the filling material are still stuck inside your mouth. Rinse gently with warm salt water to clear away any debris. Avoid poking at the tooth with your tongue or fingers, as this can irritate it further.
Protect the Exposed Tooth
The main goal is to keep the tooth safe. If you can, chew on the opposite side of your mouth and stick to softer foods. Avoid very hot, cold, or sugary items, since these can increase tooth sensitivity. You may also find temporary dental cement or filling kits at most pharmacies; these can act as a short-term barrier until your dental visit.

Manage Pain and Sensitivity
Experiencing discomfort after losing a temporary filling is common. To alleviate pain, over-the-counter medications like ibuprofen or acetaminophen can be effective. Additionally, rinsing your mouth with warm salt water can help reduce inflammation and cleanse the affected area.
You can also explore home remedies for toothache, though these are meant for temporary relief and should not replace professional dental care. If discomfort continues or worsens, it’s always best to schedule a visit with your dentist to ensure your tooth stays protected.

Extra Tips to Keep the Tooth Safe
- Use a soft-bristle toothbrush to avoid hurting the exposed area.
- Sleep with your head slightly elevated if the tooth feels sore; this can reduce throbbing.
- Keep track of any changes in pain, swelling, or sensitivity, so you can tell your dentist exactly what’s happening.
Common Reasons Temporary Fillings Fall Out
Temporary fillings are made from softer filling material and secured with dental cement, which isn’t as durable as the materials used for a permanent filling. Because of that, they’re only meant to last for a short period of time, usually a few days to a few weeks.
It’s actually quite common for a temporary filling to loosen or fall out before your dental visit. This can happen for a few simple reasons:
- Every day wear and tear: Since temporary fillings aren’t made to be strong, chewing can gradually wear them down.
- Sticky or hard foods: Things like caramel, nuts, or crunchy snacks can easily dislodge the filling material.
- Tooth decay underneath: If bacteria slip in due to poor oral hygiene, the cavity can expand and loosen the filling.
- Dental cement breakdown: Because dental cement is designed to be short-term, it can weaken faster than permanent bonding.

Temporary dental cement is designed for short-term use, so it can break down faster than permanent bonding. To help prevent cavities and keep your teeth strong while waiting for a permanent restoration, you can follow simple at-home dental care steps that support long-term oral health.
While losing a temporary filling isn’t usually an emergency on its own, leaving the tooth exposed for too long can lead to pain, sensitivity, or even infection, so it’s important to act quickly.
When to Contact Your Dentist
Even if your tooth feels okay, losing a temporary filling is a clear sign that you should schedule a dental visit as soon as possible. Temporary fillings are not meant to last long, and without proper restoration, your tooth could be at risk for decay, sensitivity, or infection.
Watch for warning signs such as sharp pain, swelling, persistent sensitivity to hot or cold foods, or any visible damage to the tooth. If the tooth or a dental crown has come loose, it’s important to act quickly.

FAQ
What should I do if my temporary filling falls out?
If your temporary filling comes out, first rinse your mouth gently with warm water to clean the area. Avoid chewing on that side and stick to soft foods. You can apply a small piece of dental cement from a pharmacy as a temporary fix, but schedule a visit with your dentist as soon as possible to prevent decay or damage to the tooth.
How long can a temporary filling be out for?
A temporary filling should not be left out for more than a day or two. The longer the tooth is exposed, the higher the risk of sensitivity, decay, or infection. It’s best to see your dentist promptly to restore the tooth with a permanent filling or crown.
Do emergency dentists do temporary fillings?
Yes, emergency dentists can place temporary fillings if needed. This is often done to protect the tooth until a permanent filling or dental crown can be applied. Emergency care helps relieve pain and prevent further complications.
Is losing a filling urgent?
While losing a temporary filling isn’t usually a life-threatening emergency, it is urgent in the sense that the tooth is vulnerable. Prompt dental attention is important to prevent decay, sensitivity, or infection. If you experience severe pain, swelling, or signs of infection, contact an emergency dentist immediately.
