What it feels like
Common causes
A blow to the mouth, a fall, sport, or another accident can displace a tooth. The injury may also affect the socket, gums, lips, or nearby teeth, so the whole mouth needs checking.
[2]| Situation | What it may indicate | Useful next step |
|---|---|---|
| Surface or shape change | The outside of the tooth has changed | Ask for an examination before choosing a cosmetic fix[2] |
| Deeper tooth problem | The symptoms or appearance suggest damage below the surface | Seek dental advice and avoid chewing on it[2] |

How to lower the chance of another problem
