| Experts say people should have their mouths examined between the ages of sixteen and twenty for placement of their wisdom teeth. 专家称，人们在 16 至 20 岁之间应该进行口腔检查以确定智齿可能萌发的位置。 X-rays can show wisdom teeth below the gums. X 光能够显示包裹在牙龈里的智齿。 Those that are not well aligned and become impacted are often removed. 那些位置不佳或者已形成阻生的智齿，通常要拔除。 The American Dental Association says removal is generally advised when wisdom teeth only partly break through the gums. 美国牙科协会称，当智齿只能部分萌出时，通常建议将其拔除； Removal is also advised if there is a chance that poorly aligned wisdom teeth will damage other teeth. 另外，如果位置不佳的智齿可能对其他牙齿造成损害，也建议拔除； |
