牙痛在英语中可以称为 "toothache"。这个词来源于两个英语单词："tooth"（牙齿）和 "ache"（疼痛）。下面是一些例句及其中文翻译：

My toothache is so bad that I can't eat anything. 我的牙痛太厉害了，以至于我不能吃任何东西。

I have to go to the dentist because I have a toothache. 我必须去看牙医，因为我牙痛。

The toothache started last night and it hasn't stopped since. 牙痛是从昨晚开始的，一直没有停止。

I took some painkillers, but they didn't help with my toothache. 我吃了些止痛药，但它们并没有帮助我的牙痛。
