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. / And the removal is performed by oral surgeons. / They say if removal is advised, the best time to do it / is before the teeth cause any problems or pain. / After surgery, there can be swelling of the gums and face and some pain. / But both can be treated with cold wraps and medicine. /
解析     智齿
   一般来说智齿是最后长出来的牙齿。它通常是在青少年时期的后期或者二十岁出头的时候长。智齿是位于口腔后部的咀嚼齿，它们可以正常长出而不引起任何问题。但通常的情况是口腔内已经没有足够的空间供它们生长，以至于它们可能会挤到其他牙齿。有时它们甚至会向旁边压迫牙龈。只冒出一部分的智齿会留下间隙给细菌进入牙齿周围。在这些情况下，通常建议你去拔掉智齿。
