Wisdom teeth are the third and last set of molars to erupt. They begin forming around the age of 10 and typically show up in the back of the mouth in the late teens or early twenties; thus the name “wisdom teeth,” as people of this age are thought to be wiser. (Though some might argue that point.)
Wisdom teeth were a necessity for our ancestors. Our ancestors needed a big jaw and a lot of teeth to chew leaves, roots, raw meat, and other tough foods. Our diets are different now; we no longer need all of those teeth which is good since our jaw is smaller, and now we don’t have room for an extra set.
The number of wisdom teeth a person has can vary. Some people never get wisdom teeth. Some people can have them their whole lives with no problem. But many people do have a problem, and approximately 85% of wisdom teeth will need to be removed.
