Wisdom teeth, also known as third molars, are the last teeth to grow in the back of the mouth. Common misunderstandings surround their name origin, removal reasons and pain sources, according to the Academy of General Dentistry (AGD), an organization of general dentists dedicated to continuing education.

"The name 'wisdom teeth' is age-related – third molars don't erupt until teenage years and beyond, when people theoretically are more wise to the world," says AGD spokesperson Trey Petty, DDS, FAGD.
