I once bought a time when I came to America as a dentist, I was working as a dentist but I also was running a restaurant, and one of my really good looking waiters was sure that he wanted whiter teeth, so he was consistently whitening his teeth with artificial whitening products.
有一次,我作為一名牙醫來到美國,當時我既是一名牙醫,也在經營一家餐館,我的一位非常帥氣的服務員很肯定地告訴我,他想讓自己的牙齒更白,所以他一直在用人工美白產品美白自己的牙齒。
