假牙在英语中叫做 dentures。它的来源可能源自拉丁语"dentis"，意思是牙齿，和"dentur"，意思是拥有牙齿。

例句：

She wears dentures because she lost all her teeth. 她戴假牙是因为她掉光了所有的牙齿。

He needs to remove his dentures before going to bed. 他需要在睡觉前摘掉假牙。

I can't eat this apple, my dentures don't fit well. 我吃不了这个苹果，因为我的假牙不合脸。

The dentist will adjust the fit of your dentures. 牙医会调整你假牙的合脸度。
