Wisdom Tooth Problems
Wisdom teeth are the last molars to come through, often in the late teens or twenties. They can get stuck (impacted) and cause pain, swelling and infection.
Causes & risk factors
- Not enough space in the jaw
- Teeth coming in at an angle (impaction)
- Partially erupted teeth trapping food and bacteria
- Difficulty cleaning teeth at the back
- Pressure on neighbouring teeth
Common symptoms
- Pain at the back of the jaw
- Swollen, red gum over the tooth
- Difficulty opening the mouth
- Bad taste or bad breath
- Swollen glands
- Pain when chewing
Tests & diagnosis
- Dental examination
- Dental X-ray or OPG
- Assessment of tooth position
Treatment & management
- Salt-water rinses and good cleaning for mild cases
- Treating any gum infection
- Pain relief for comfort
- Removal (extraction) of problem wisdom teeth
- Keeping healthy, well-positioned wisdom teeth under review
When to see a doctor urgently
- Severe pain or swelling at the back of the jaw
- Difficulty opening the mouth or swallowing

Frequently asked questions
Do all wisdom teeth need to be removed?
No. Healthy wisdom teeth that come through properly and can be cleaned may be left alone. Removal is for those causing pain, infection or crowding.
What is an impacted wisdom tooth?
It is a wisdom tooth that cannot fully come through, often because there is not enough space, so it stays partly or fully under the gum and can cause problems.
