Wisdom tooth removal
The wisdom teeth grow at the back of your gums and are the last teeth to come through. Most people have four wisdom teeth – one in each corner.
Wisdom teeth usually grow through the gums during the late teens or early twenties. By this time, the other 28 adult teeth are usually in place, so there isn’t always enough room in the mouth for the wisdom teeth to grow properly.
Why are wisdom teeth removed?
Your wisdom teeth don’t usually need to be removed if they’re impacted but aren’t causing any problems. This is because there’s no proven benefit of doing this and it carries the risk of complications.
Sometimes, wisdom teeth that have become impacted or haven’t fully broken through the surface of the gum can cause dental problems.
