Why are they called “wisdom” teeth?

Third molars have been referred to as “teeth of wisdom” since the Seventeenth Century and simply “wisdom teeth” since the Nineteenth Century. The third molars generally appear much later than other teeth, usually between the ages of 17 and 25 when a person reaches adulthood. It is generally thought among linguists that they are called wisdom teeth because they appear so late, at an age when a person matures into adulthood and is “wiser” than when other teeth have erupted.

Lately, science has added some credence to the idea that the third molar does indeed erupt when a person is “wiser”. Recent research has shown the brain continues to grow and develop right on through adolescence: in fact, most researchers believe the brain does not reach full maturity until the age of 25. Perhaps, then, our ancestors weren't so far off the mark — that the eruption of “wisdom teeth” is a sign that the carefree days of childhood have given way to the responsibilities of adulthood.

The old saying, “If it ain't broke, don't fix it,” doesn't really apply when discussing your wisdom teeth. It's great if they are not bothering you, but don't wait for problems to develop before you take action. This may seem counter-intuitive, but you should know that the best time to have your wisdom teeth removed is when they are not causing problems

Why do wisdom teeth cause problems?
For some people they come through the gum-line only partially, or they may not erupt into the mouth at all. Unerupted they have the potential to cause problems associated with the neighboring teeth and surrounding gums.

You may have heard of “impacted” wisdom teeth. This means that they are impacted or forced against neighboring structures, teeth or bone that prevent them from coming into the mouth in correct biting position. Since they are your last teeth to come in, space for them may be severely limited. They may push into the teeth that are already in place, becoming stuck as they try to erupt. When wisdom teeth are trapped like this below the gum line and are pushing against neighboring teeth, these molars can cause problems such as infections, cysts, or gum disease.
