答案 Wisdom Teeth Wisdom teeth are normally the last teeth to appear. / This usually happens when people are in their late teen years or early twenties. / Wisdom teeth are chewing teeth at the back of the mouth. / They can grow into place normally and never cause a problem. / But often there is not enough room for them in the mouth / so that they might crowd other teeth. / Sometimes they even push sideways through the gums. / Wisdom teeth that only partially erupt / can leave space for bacteria to enter around the tooth. / In these cases, you are often advised to get them removed. /
