Thanks, doc. I’ve got a really bad toothache! I can’t eat anything, and look, my face is all swollen. I think it might be my wisdom tooth.

谢谢，医生，我的牙齿真的疼死了！我完全不能吃任何东西，看，我的脸都肿了。我想这可能是我的智齿。

In that case, instead of growing in like a normal tooth wisdom teeth get trapped or impacted in your jaw, which often makes them grow in at odd angles and press against your back molars causing pain and swelling.

这样的话，智齿有可能困住或被压着，没有办法像正常的牙齿那样生长。所以它们经常以奇怪的角度长出来，还会挤压你的后臼齿，让你感到疼痛和肿胀。
