20歲只有26隻牙

It may be come out or may not be.......
If you really want to know, better check with dentist......
Because they will take a X-ray with your teeth......
If the teeth is under the gum.....they can see though X-ray.......

In my experience, I saw some case will see the teeth have some problem that need to do something to let them out........eg......the teeth doesnt got enough space to come out.....then should treat it...
otherwise, they will cause a problem in several years later.....


then you are better to check with dentist........at least you know what are they going on..

通常成人總共有 32隻牙，
上下排各有 2隻智慧齒(共 4隻)，
但因人而異，有些人是不會出齊的，
亦有些人不會出智慧齒。
你現在還年輕，所以未出齊都不用擔心，
但平時要注意口腔衛生，
牙齒都會健康D。

不用太擔心。
