每天刷牙两次已足够了(早起和临睡前)。很多人刷牙次数超过了推荐次数——尤其是在吃过大餐后。
Brushing your teeth twice a day (in the mornings and last thing at night) is sufficient. Many people brush more than the recommended number of times per day - especially after a big meal.
每天用含氟牙膏刷牙两次也是非常重要的，记住要在饭后一个小时后也要这样做，还有，不要忘记了定期去看牙医。
It is also important to brush your teeth twice a day using fluoride toothpaste, waiting an hour to do so after meals, and to visit your dentist regularly.
只刷牙绝对不够，还要按摩牙龈、清洁舌头、漱喉咙，这些每天都要来两次。
Brushing only your teeth is definitely not enough. Massage your gums, clean your tongue and gargle your throat twice a day.
