You need to systematically go round all the surfaces of your teeth with fluoride toothpaste, for at least two minutes, twice a day. Unfortunately, we live such busy lives that putting two minutes aside feels like a lifetime for some people. 你需要有系统地使用氟化物牙膏绕你牙齿的所有表面，持续至少两分钟，一天两次。不幸的是，我们过着忙碌的生活，所以留出两分钟对一些人来说就像一辈子一样。 Your teeth tend to be a bit softer just after eating, so wait at least half an hour. Then brush all along the gum line with a little scrubbing action. Don't press too hard, or to be too light. 吃完东西后，你的牙齿会变软一点，所以至少要半个小时后才能刷牙。然后沿着牙龈线轻轻洗刷一下，不要太用力，也不要太轻。 |
