Wisdom teeth are the last molars on each side of the jaws. They are also the last teeth to emerge, or erupt, usually when a person is between 16 and 20. Since wisdom teeth are the last permanent teeth to come in, there is often not enough room left in your mouth to accommodate them. This can lead to wisdom teeth that are impacted, teeth that are trapped beneath the gum tissue by other teeth or bone. If teeth are impacted, swelling and tenderness may occur. Wisdom teeth that only partially emerge or come in crooked can also lead to painful crowding and disease.
