Why are they called "wisdom teeth?"

"Wisdom teeth" refers to a person being older and wiser when the teeth emerge. They were called "teeth of wisdom" throughout the 17th century, until the name was gradually shortened to "wisdom teeth" in the 19th century.

Wisdom teeth typically appear between the ages of 17 and 25. They are the third and final set of molars to appear. The average person has four, but it is normal to have fewer. They can cause several problems as they grow. Wisdom teeth can become impacted and cause damage to the jaw or shift the alignment of other teeth. If any problems occur, they can be removed with oral surgery.
