It’s Friday evening, you’re eating dinner, and suddenly something hard comes loose in your mouth. Your tooth filling has fallen out, and now there’s a hole where it used to be. The tooth might feel sharp, sensitive, or perfectly fine for the moment, but what should you do until you can see a dentist?
A temp dental filler may help protect the exposed area for a short time. However, it won’t repair a broken tooth, remove decay, or treat an infection. Knowing when to use one, and when to leave the tooth alone, can save you from making an uncomfortable situation worse.
Here’s what to do when a filling falls out, how to manage the discomfort, and which temporary fixes are safe while you arrange dental care.
Your Filling Fell Out. What Should You Do First?
First, don’t panic. Losing a filling doesn’t automatically mean you’ll lose the tooth. However, the exposed area needs attention because food, bacteria, and temperature changes can irritate the tooth underneath.
If your permanent tooth filling fell out, follow these steps:
- Remove any loose material from your mouth. If the filling is still in your mouth, take it out carefully so you don’t accidentally swallow or choke on it. Don’t try to put the old filling back into the tooth.
- Rinse gently. Use lukewarm water or a mild saltwater rinse to clear away food particles. Avoid aggressive swishing if the area feels painful.
- Check for obvious damage. Look for a missing filling, sharp edge, or broken tooth fragment. Don’t poke inside the opening to see how deep it goes.
- Protect the tooth while eating. Chew on the opposite side, avoid hard foods, and keep the exposed area clean.
- Call your dentist. Explain when the filling came out, whether the tooth hurts, and whether any part of the tooth broke.
If the tooth has a small opening and you can’t access dental care immediately, an appropriate temporary filling product may provide short-term coverage. However, severe pain, swelling, bleeding, or a visibly broken tooth needs professional advice before you attempt a repair.
At Smile For Miles Dental, we can examine the exposed tooth and determine whether you need a replacement dental filling in Colleyville or another treatment.
Why Does a Tooth Hurt When a Filling Falls Out?
A filling covers and restores part of a tooth that has lost structure. When it falls out, the underlying tooth can become exposed to cold air, drinks, food, and chewing pressure.
You may notice a quick sting when drinking cold water, pain when eating something sweet, or an uncomfortable feeling when your teeth touch. Sometimes the pain comes from decay beneath the old filling or a crack that weakened the tooth.
The type of pain matters. A brief reaction to cold is different from constant throbbing, pain that wakes you up, or discomfort that spreads toward your jaw.
What Helps With Pain After a Filling Falls Out?
If the discomfort is mild, you can take a few steps to make the tooth more comfortable before your appointment.
- Avoid temperature triggers: Choose lukewarm drinks if hot coffee or cold water causes sensitivity.
- Eat softer foods: Scrambled eggs, yogurt, soft pasta, and mashed potatoes place less pressure on the exposed tooth.
- Keep the area clean: Brush gently and rinse after eating so food doesn’t collect in the opening.
- Use appropriate pain relief: An over-the-counter pain reliever may help if it’s safe for you. Follow the package directions or your dentist’s advice.
- Stop chewing on the painful side: Repeated pressure may aggravate a cracked or weakened tooth.
Don’t place aspirin directly against the tooth or gum. It can irritate or burn oral tissues, and it won’t repair the missing filling.
If the tooth keeps throbbing, hurts whenever you bite, or becomes increasingly sensitive, contact your dentist. Our article on tooth pain after a filling explains what different symptoms may indicate.
Can You Use a Temporary Tooth Hole Filler?
That depends on why the hole is there. If an old filling has fallen out and left a small opening, a temporary tooth filling product may help cover the exposed area until a dentist can examine it.
But a hole caused by an untreated cavity is different. Placing material over active decay doesn’t remove the damaged tooth structure or stop the problem underneath.
Before using any tooth hole filler, pay attention to the symptoms and the condition of the tooth.
| Your Situation | Can Temporary Filler Help? | What to Do |
|---|---|---|
| Small lost filling | Possibly, for brief protection | Follow the product label and arrange dental care. |
| Hole from untreated decay | Does not treat the cavity | Have a dentist examine and treat the decay. |
| Broken or cracked tooth | Cannot repair the damaged structure | Avoid chewing there and contact a dentist. |
| Lost filling with mild sensitivity | May temporarily reduce exposure | Protect the tooth briefly and book an examination. |
| Swelling, fever, or severe throbbing | Not an appropriate home solution | Seek urgent dental assessment. |
A temporary filler may make an exposed tooth feel more comfortable, but that doesn’t mean the underlying problem has disappeared. The dentist still needs to check for decay, cracks, and damage around the old filling.
Can You Use a Temporary Filling on a Broken Tooth?
A broken tooth needs more care than a missing filling. If a piece of the tooth has chipped away, an over-the-counter filler cannot rebuild its strength or stop a crack from spreading.
For a small chip without significant pain, you can rinse gently, avoid biting on the damaged tooth, and contact your dentist. If the edge cuts your tongue or cheek, dental wax intended for oral use may temporarily cover the sharp edge.
If a large piece breaks off, you experience sharp pain when biting, or the tooth feels loose, arrange urgent dental assessment. Don’t try to rebuild the tooth with household glue or temporary filling material.
What About a Front Tooth?
A missing filling on a front tooth may leave a visible gap or rough edge. Even if it doesn’t hurt, biting into food can place pressure on the weakened area.
Temporary material may provide limited coverage in some situations, but it won’t reliably restore the tooth’s original appearance or strength. Front teeth also need careful shaping so they don’t interfere with your bite.
Until your appointment, avoid biting directly into apples, crusty bread, or other firm foods. Cut food into smaller pieces and chew with teeth that feel comfortable.
Store-Bought Temporary Filler or Dentist?
Pharmacies sell temporary tooth filling kits for certain lost fillings and loose dental crowns. Products such as Dentemp and DenTek can provide short-term protection when you can’t reach a dentist immediately.
However, not every kit suits every situation. A product designed for a lost filling may not be appropriate for a broken tooth, an untreated cavity, or a tooth with severe pain.
Follow the instructions for the exact product you’re using. Different materials have different application methods, setting times, and precautions.
For more information about pharmacy products, read our article on OTC temporary filling kits, including how to use them and which mistakes to avoid.

What Can a Dentist Do That a Store Kit Cannot?
A dentist can look beyond the visible opening. During an examination, we can check whether decay weakened the old filling, whether the tooth has cracked, and whether your bite places extra pressure on the damaged area.
Depending on the findings, your dentist may clean and restore the tooth, adjust its bite, take dental X-rays, or recommend a different treatment.
A store-bought kit cannot perform those checks. It can only provide temporary coverage when the situation is suitable for home use.
If you’re weighing short-term protection against a lasting restoration, our article on temporary dental filling vs. professional treatment explains the differences in durability, cost, and purpose.
How Long Does Temp Dental Filler Last?
A temp dental filler may stay in place for a few days or longer, depending on the product, tooth structure, and chewing pressure. Dentist-placed temporary restorations follow different treatment timelines, so there isn’t one lifespan that applies to every material.
A repair on a back tooth may face heavy chewing pressure, while a front tooth has different biting demands. Either can lose temporary material if the opening is large, the tooth is damaged, or the material doesn’t hold securely.
If you’re using an OTC kit, follow its instructions and arrange dental care as soon as possible. Don’t assume the tooth is repaired simply because the filler stays in place.
Signs Your Temporary Filling Is Failing
You might notice the problem before the material falls out completely. Watch for these changes:
- The filling feels loose or moves when you chew.
- A rough or broken edge develops.
- Food starts collecting around the opening again.
- Your bite suddenly feels uneven.
- Cold sensitivity returns or becomes stronger.
- You notice new pain when biting.
If the temporary filling keeps falling out, don’t keep adding more material without getting the tooth checked. A large opening, weak tooth structure, decay, or bite pressure may be preventing the repair from holding.
Our article on temporary tooth filling problems explains why fillings loosen, break, or repeatedly fail.
What Can You Eat With a Temporary Filling?
Food choices matter while you’re protecting an exposed tooth. Hard or sticky foods can dislodge temporary material, while extreme temperatures may trigger sensitivity.
Choose foods that require less chewing, especially while the tooth feels tender.
| Easier Choices | Avoid for Now | Why |
|---|---|---|
| Scrambled eggs, yogurt, soft pasta | Hard chips, nuts, ice | Hard foods can crack or loosen the material. |
| Mashed potatoes, oatmeal | Caramel, gum, sticky candy | Sticky foods may pull temporary filler away. |
| Lukewarm drinks, soft cooked vegetables | Very hot or icy drinks if sensitive | Temperature changes may irritate exposed tooth structure. |
Chew on the opposite side whenever possible, and follow the product’s setting-time instructions before eating. Don’t test the temporary filling by biting down hard to see whether it holds.
How Should You Clean the Tooth?
Keep brushing your teeth, but use a gentle touch near the temporary restoration. A soft-bristled toothbrush can help remove plaque without putting unnecessary pressure on the area.
Follow your dentist’s advice about flossing around temporary dental work. If floss catches on the material or pulls at its edge, don’t force it. Contact the dental office for instructions.
What Should You Never Put in a Tooth Hole?
When a filling falls out at night, it’s tempting to use whatever you can find at home. But household materials aren’t designed for dental repairs, and some can cause additional damage.
| Do Not Use | Why It’s Risky |
|---|---|
| Super glue | Household adhesives can irritate oral tissues and interfere with dental treatment. |
| Chewing gum | Gum can trap debris and doesn’t provide a reliable dental seal. |
| Aspirin placed on the tooth | Direct contact can burn or irritate gum tissue. |
| Tissue or cotton packed into the hole | These materials can collect food, saliva, and bacteria. |
| Pins, needles, or sharp toothpicks | Sharp tools can injure the gums or damage exposed tooth structure. |
If you’re unsure what to put in the opening, keeping it clean and avoiding chewing on that side is safer than experimenting with household materials.
When Is a Lost Filling an Emergency?
A lost filling doesn’t always require a hospital visit. If you have mild sensitivity, no swelling, and no significant tooth damage, contact your dentist to arrange an appointment as soon as practical.
Some symptoms need faster attention because they may point to infection, trauma, or damage that temporary filler cannot manage.
Call a Dentist Promptly If You Notice:
- Severe or worsening tooth pain
- Throbbing that keeps you awake
- Swelling around the gum, cheek, or jaw
- Fever alongside dental pain
- Pus or a persistent unpleasant taste
- A broken tooth with significant pain
- Pain every time you bite or chew
These symptoms need a dental examination rather than repeated attempts to cover the tooth. If you’re dealing with urgent tooth pain in Colleyville, our emergency dental care service can help you arrange an assessment.
Lost a filling or dealing with tooth pain?
We can check the exposed tooth, look for cracks or decay, and explain whether you need a new filling or another repair.
Should You Go to the Dentist or Emergency Room?
For most lost fillings, damaged restorations, and toothaches without dangerous symptoms, a dentist is the right place to start. Dental offices can examine the tooth and provide the treatment needed to repair it.
Go to an emergency department immediately if swelling affects your breathing or swallowing, you have uncontrolled bleeding, or you suffer serious facial or jaw trauma. Severe swelling with difficulty opening your mouth also needs urgent medical assessment.
Hospital emergency departments can manage serious medical complications, but they usually don’t provide permanent fillings or routine dental repairs. You’ll generally need dental follow-up after the medical emergency is addressed.
If you’re unsure whether your symptoms need urgent attention, our article on the signs you need emergency dental care can help you recognize problems that shouldn’t wait.
How Will Your Dentist Repair the Tooth?
Once you’re at the dental office, the next step is finding out why the filling failed and how much healthy tooth structure remains. Some teeth need a straightforward filling replacement, while others need more support.
| Treatment | When It May Be Needed | What It Does |
|---|---|---|
| Replacement filling | The tooth has enough healthy structure for another filling. | Restores the damaged area after necessary treatment. |
| Dental crown | A large filling or fracture has weakened the tooth. | Covers and protects the remaining tooth structure. |
| Root canal treatment | The tooth’s pulp has severe inflammation or infection. | Treats the affected pulp while preserving the tooth when possible. |
| Extraction | The tooth cannot be restored. | Removes a tooth that cannot be saved. |
If the tooth has a large crack or has lost substantial structure, your dentist may recommend a dental crown rather than another filling. A crown can help protect a weakened tooth during normal chewing.
When decay or damage affects the pulp inside the tooth, a filling alone may not solve the problem. Your dentist can check whether root canal therapy is necessary.

FAQs
What should I do if my tooth filling fell out?
If your tooth filling fell out, remove any loose material from your mouth, rinse gently with lukewarm water, and avoid chewing on the exposed tooth. A suitable temporary dental repair product may offer brief protection if the symptoms are mild and the product instructions allow it. Call your dentist so they can check why the filling came out and arrange the right repair.
What can I use as a temporary tooth hole filler?
A pharmacy product intended for lost fillings may temporarily cover an exposed opening until you can see a dentist. However, it won’t treat an untreated cavity or repair a cracked tooth. Avoid household materials such as glue, gum, or tissue, and have the tooth examined even if the temporary covering feels comfortable.
What helps with pain after a tooth filling falls out?
Mild pain after a lost filling may improve when you avoid cold drinks, chew on the opposite side, and keep food out of the opening. You can also use an over-the-counter pain reliever if it’s safe for you and you follow the label. If the pain throbs, becomes stronger, or comes with swelling, contact a dentist promptly.
Can you use a temporary filling on a broken tooth?
A temporary filling kit cannot repair a broken tooth or prevent a crack from spreading. Some products specifically warn against use on broken teeth, so check the instructions before attempting anything at home. If the tooth has chipped or fractured, avoid chewing on it and arrange a dental examination to find out which restoration it needs.
Can I use a temporary filling on a front tooth?
A temporary material may cover a small lost-filling area on a front tooth in certain situations, but it isn’t a reliable way to rebuild a chipped or fractured tooth. Front teeth need careful shaping for biting and appearance. Avoid biting into firm foods and ask your dentist whether the tooth needs bonding, a replacement filling, or another restoration.
How do I use a temporary tooth filling kit?
Start by reading the directions for the exact product you’ve purchased, whether it’s Dentemp, DenTek, or another temporary repair material. Product instructions vary, including how to prepare the area, place the material, and how long to wait before eating. Don’t use the kit if your symptoms or tooth damage conflict with its warnings. Arrange professional dental care after the temporary repair.
How long does a temp dental filler last?
A temp dental filler may stay in place for days or longer, depending on the material, tooth location, and amount of chewing pressure. Dentist-placed temporary restorations may follow a different timeline. There’s no guaranteed lifespan that applies to every product, and a temporary filling should never replace the treatment your tooth actually needs.
Can I eat with a temporary dental filling?
Yes, you can usually eat after the material has set, but follow your dentist’s advice or the product’s instructions about timing. Choose softer foods, avoid sticky candy and hard snacks, and chew on the opposite side when possible. If the filling feels loose, high, or painful when biting, stop chewing on that tooth and contact your dentist.
What if my temporary filling keeps falling out?
If a temporary filling keeps falling out, the opening may be too large, the tooth may have weakened, or your bite may be putting extra pressure on the area. Don’t keep adding material without finding out why it won’t hold. A dentist can examine the tooth and determine whether you need a replacement filling, crown, or another repair.
How do I remove a temporary filling at home?
Don’t dig, scrape, or pull out a temporary filling yourself. You could damage the tooth, irritate the gums, or expose an area that still needs protection. If the material feels too high, loose, painful, or uncomfortable, contact your dentist for help. They can remove or replace it safely and check the tooth underneath.
Can I use super glue to repair a tooth?
No, household super glue isn’t safe for repairing a tooth or replacing a lost filling. It can irritate oral tissues and make professional dental treatment more difficult. If a filling has fallen out, keep the area clean, avoid chewing on that side, and use only an appropriate dental product when its instructions allow it.
When should I see a dentist instead of using temporary filler?
Contact a dentist promptly if your tooth has severe pain, a large crack, swelling, pus, fever, or worsening sensitivity. Even a painless lost filling deserves an examination because decay or damage may remain beneath the opening. Seek emergency medical care if facial swelling affects your breathing or swallowing, or if you have serious facial trauma.
