Wisdom teeth

rearmost teeth of the mouth that erupt during adulthood

Wisdom teeth are a set of four teeth, farthest back in a person's mouth. Most people get them late in their teenage years or in their early twenties.[1] Many people have to have surgery to get rid of them because they often grow in a crooked way, or because there is no room for them. [2]
