What should I do if a filling falls out?
Direct answer
If a filling falls out, avoid chewing hard food on that tooth, keep the area clean and book a dental assessment. The tooth may feel sensitive, sharp or more exposed to decay and cracks. Seek faster care if you have toothache, swelling, a bad taste, fever, a large broken piece or pain when biting.
Why a lost filling should be checked
A filling protects a part of the tooth that has already been damaged, restored or weakened. When it falls out, the tooth surface underneath can become exposed.
Even if the tooth does not hurt, there may be decay, leakage, a crack or weakened tooth structure under the old filling. Pain is not always a reliable measure of how serious the problem is.
What should you do immediately?
- Avoid chewing on the affected tooth until it has been assessed.
- Brush carefully and keep the area clean.
- Rinse with water if food gets trapped in the cavity.
- Save the filling if you find it, but do not try to glue it back yourself.
- Avoid very hard, sticky or sugary foods that can lodge in the tooth.
- Book a dental appointment for assessment and repair.
What the dentist may need to check
| What is checked | Why it matters | Possible outcome |
|---|---|---|
| New decay | Decay around or under an old filling may be why it loosened. | The tooth may need cleaning and a new restoration. |
| Cracks in the tooth | A crack can change whether a simple filling is enough. | A crown or other protection may be needed. |
| Remaining tooth structure | A heavily weakened tooth may not support another ordinary filling. | A larger restoration may be recommended. |
| Nerve involvement | Deep decay or trauma close to the nerve can cause pain. | Root canal treatment may be considered if the nerve is affected. |
| Bite pressure | Grinding or heavy bite forces can break restorations. | Bite adjustment or a night guard may be discussed. |
What happens at Gloss & Floss Dental Care®?
At Gloss & Floss Dental Care® in Stockholm, we examine the tooth, listen to your symptoms and assess why the filling has fallen out. X-rays may be needed to check for decay, cracks, depth of damage or nerve involvement.
Treatment depends on the findings. Some teeth can be repaired with a new filling. More weakened teeth may need a crown, and teeth with infection or nerve involvement may need additional treatment.
When should you seek care?
A lost filling is not always a same-hour emergency, but it should be assessed sooner if the tooth hurts, feels sharp, traps food or is painful when biting.
Practical advice: Do not use household glue or sharp objects in the cavity. Temporary pharmacy material may protect the tooth briefly, but it does not replace dental assessment.
Frequently asked questions
Is a lost filling always an emergency?
Not always. If there is no pain and you can keep the area clean, it may sometimes wait briefly. The tooth should still be checked.
Can I use temporary filling material from a pharmacy?
Temporary material may protect the tooth for a short time, but it does not replace a dentist’s diagnosis or repair.
Why did my filling fall out?
Common reasons include decay, a crack, wear, heavy bite forces, grinding or leakage around an old restoration.
Can the tooth be repaired with a new filling?
Often yes, if the damage is limited and enough healthy tooth remains. If the tooth is weakened, a crown may be more suitable.
