Wisdom teeth are normally the last teeth to appear. This usually happens when people are in their late teen years or early twenties-in other words, when they are older and wiser. 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. They might crowd other teeth. Sometimes they even push sideways through the gums(牙床). An impacted wisdom tooth is one that fails to completely rise through the gum-the term is erupt. Wisdom teeth that only partially erupt can leave space for bacteria to enter around the tooth. Infection is a risk in these cases. Wisdom teeth’that are not well in place and become impacted are often removed. People should have the placement of their wisdom teeth examined between the ages of sixteen and twenty. X-rays can show wisdom teeth that are below the gums. The American Dental Association says removal is generally advised when wisdom teeth only partly break through the gums. Removal is also advised if there is a chance that poorly placed wisdom teeth will damage other teeth. And removal is called for in cases where fluid collects around a wisdom tooth that is partly or fully below the gum. But why do we have wisdom teeth if we often need to get them removed One theory has to do with our diets. Scientists say the diet of prehistoric humans probably required more chewing teeth. Life was probably a little rougher on the teeth back then, too. So it was good to have extras. The American Association of Oral and Maxillofacial (上颌面的) Surgeons says young adults are the best candidates for wisdom teeth removal. The group says older patients may be at greater risk for disease in the tissue surrounding the teeth. After surgery, there can be swelling of the gums and face and some pain. Both can be treated with cold wraps and medication(药物治疗).The problem wisdom teeth should be removed early, because (). A. older patients will feel more pain B. older patients may face more serious problems C. wisdom teeth are easier to be removed at young age D. young people have stronger resistance to diseases

题目解答
答案
B
解析
问题涉及智慧齿的移除时机。根据文章，智慧齿是最后长出的牙齿，通常在青少年晚期或二十岁初期出现。它们可能会因为没有足够的空间而拥挤其他牙齿，或者部分长出，导致感染风险。因此，需要移除那些位置不佳或部分长出的智慧齿。
步骤 2：分析选项
A. 老年患者会感到更多疼痛：文章没有提到老年患者会比年轻患者感到更多疼痛。
B. 老年患者可能面临更严重的问题：文章提到，老年患者可能面临更大的风险，因为组织周围的疾病风险增加。
C. 智慧齿在年轻时更容易被移除：文章没有直接提到这一点，但提到年轻成年人是移除智慧齿的最佳候选人。
D. 年轻人对疾病有更强的抵抗力：文章没有提到这一点。
步骤 3：选择正确答案
根据文章内容，老年患者可能面临更大的风险，因为组织周围的疾病风险增加。因此，问题智慧齿应该尽早移除，因为老年患者可能面临更严重的问题。
