Wisdom teeth are the last teeth to erupt in the mouth. They are the third set of molars that typically emerge between the ages 17 and 25.
They do not cause problems as long as they come through in the right position. However, if there is not enough room for them to grow in, if they are unable to erupt fully through the gums, or if they are impacted or trapped in your jaw under your gums, your wisdom teeth may need to be extracted.
