The short answer
Wisdom teeth are the last molars to appear, usually in the late teens or twenties. When there is not enough space they can become impacted, partly erupt, trap food and cause pain, swelling and infection. Not every wisdom tooth needs removal, so assessment with an X-ray comes first.

Wisdom Tooth Care: frequently asked questions
Do all wisdom teeth have to be removed?
No. If a wisdom tooth is healthy, fully erupted and easy to clean, it can often stay. Removal is advised when it causes or is likely to cause problems.
How painful is wisdom tooth removal?
The procedure is done under local anaesthesia, so you should not feel pain. Soreness and swelling for a few days afterwards are normal and manageable.
How long is recovery?
Most people feel much better within a few days, although complete gum healing takes longer. Following the aftercare instructions helps recovery.
What is dry socket?
Dry socket happens when the blood clot is lost from the extraction site, causing increasing pain after a few days. Avoid smoking, spitting and straws, and call the clinic if pain worsens.
