A wisdom tooth causes trouble when it can’t come through properly. Impacted teeth sit under the gum or only partly through it, and that makes them hard to keep clean (ADA, teeth.org.au, wisdom teeth).
- Most jaws don’t have enough room for wisdom teeth to come through easily (ADA, teeth.org.au, wisdom teeth).
- Inflamed gum, decay and pain are the usual first signs.
- Facial swelling with fever needs prompt care.
Why do problems start?
Bacteria collect around a tooth that’s only partly through, and the gum can become inflamed. That’s called pericoronitis (ADA, teeth.org.au, wisdom teeth).
A wisdom tooth sitting at an angle can also bump the tooth in front. Decay can then develop on the wisdom tooth or on the tooth next to it (ADA, teeth.org.au, wisdom teeth).
What signs should you watch for?
Book an assessment if you notice:
- pain or tenderness at the back of your mouth;
- swollen, red gum over a tooth that’s partly through;
- a bad taste, or bad breath that keeps returning;
- trouble opening your mouth fully;
- food catching behind your back teeth.
When is it urgent?
Get prompt help if your face or neck swells, you have a fever, or you can’t swallow or open your mouth easily. Phone us right away. Trouble breathing or swallowing means calling 000 or heading to an emergency department.
How do we assess wisdom teeth?
We examine the area and usually take an X-ray to see the tooth’s position and roots (ADA, teeth.org.au, wisdom teeth). Pain by itself doesn’t mean a tooth has to go. Cleaning the area better, or treating an infection, sometimes settles the problem.
An antibacterial mouthwash can help when brushing is painful because the gum is inflamed, but it doesn’t replace brushing (ADA, teeth.org.au, wisdom teeth).
If removal is recommended, we explain the risks and alternatives, and whether a referral suits you. Read does everyone need their wisdom teeth removed.
