A majority of people have at least one impacted wisdom tooth, which will have to be removed with surgery.
But a new study shows a common pediatric procedure may prevent wisdom teeth from developing at all. Wisdom teeth do not begin to develop until well after birth, making them vulnerable to injury.
Researchers at Tufts University studied the dental X-rays of two to six year-olds who had received local, dental anesthesia, and compared them to children who had not.
They found those who had received anesthesia were four times more likely to have missing wisdom tooth buds.
