If you’re like this writer, your mouth may have never gotten the memo that it was supposed to grow wisdom teeth. On the other hand, you might be one of the many people subjected to having them removed.
Well for those who fear becoming the latter of the two, it looks like evolution is running in your favor- we’re gradually losing our wisdom teeth. Scientists are a bit puzzled over the disappearance of wisdom teeth because they are the only ones to develop entirely after birth, and thus it is harder for nature to select against them.
The way these teeth grow is by the tooth building tissue slowly moving to the back of the jaw to start the process. When this doesn’t happen, wisdom teeth don’t grow. Some scientists are aiming to outright get rid of these teeth permanently. Because wisdom teeth don’t start to appear for a dozen or so years, they think it’s possible to use a laser or chemical to prevent the teeth from growing.
It’s been estimated that two thirds of wisdom teeth removal surgeries aren’t necessary, and given the great deal of pain that comes with removing them, many believe preventing their growth altogether is a good idea.
