Most Americans visit dentists to have their teeth checked. Dentists state that 2 visits a year are desirable. However, most people go only once a year. Americans visit dentists much more frequently than most other people in the world. Still, there are many adults who have never been inside a dentist's office. And some of these people are in need of a dentist's care.

大多数美国人去看牙医作牙齿检查。牙医指出，一年查两次是必要的。然而，大多数人每年只看一次。美国人看牙医比世界上大多数人都勤快，但仍然有些成人从未踏进牙医诊所半步，这些人当中有些是需要牙医照料的。
