饭后立马刷对牙不好， 吃了acidic food 要等30分钟刷。 it's a good idea to brush your teeth before eating an acidic food and to drink a glass of water when you are finished to wash away the acids.
if you've consumed anything acidic, you should avoid brushing your teeth for at least 30 minutes. Foods containing citric acid , like oranges, grapefruits and lemons, weaken tooth enamel. Brushing too soon after eating them can damage the enamel in its weakened state.
家人有牙医。 他也这么说的。 You may be surprised to learn that brushing immediately after a meal may actually harm your teeth. Acids created by food can wear away your protective enamel leaving your teeth at their weakest state right after you eat.

到底何时刷牙效果最好
睡前刷干净，用牙线漱口水，早上起来口气也很清新
睁眼就得找咖啡续命啊
哈哈，一样的，都还没起床洗脸刷牙，就要吃东西了，有点难以接受
当然是饭后刷牙。早上睁眼漱口就行了。睡觉一晚上哪来的那么多怪味。
好奇，为什么特别指出“早饭”，难道中饭（如果条件允许的话）跟晚饭都是饭前刷吗？
饭后刷一上午都是清新的多好
吃了就刷。等啥？
饭前漱口就好了。

饭后 Waterpik 就好啊 再说中午也要刷牙啊 。

刷牙是为了保护牙齿的，饭前刷算什么....
你时时刻刻都有口水，口腔细菌当然会进入食道了，完全不用介意吧，我支持饭后刷 ---发自Huaren 官方 iOS APP

我跟你一样。不刷牙没法说话吃东西。难受。
同意！
我听说晚上睡觉的时候因为嘴里不分泌口水，有很多细菌滋生，所以起床就刷牙，饭后漱口就好。
不知道对否，但是早上起床后嘴里味道不好，刷牙后感觉舒服些。
那你早饭前后都要刷吗？ 一天3次？
牙不好，我都刷
请问为什么早饭后要刷牙，午饭和晚饭后不刷呢？
如果饭后都要刷牙的话，一天要刷3次。如果包括早上起床和睡前一次，那一天刷5次牙？

不是刷牙次数越多越好。因为刷太多会损伤牙龈，如果牙龈没有机会修复，会导致牙龈萎缩，年纪大了过早出现牙床流失，牙齿松动的毛病。
现在牙医一般不会建议刷三次，如果实在需要，一般都是用专门处方的漱口水在午饭，晚饭后清理。

这个牙医界一直有争议，因为到底是食物中的酸对牙齿损伤厉害，还是细菌转化糖变成的酸对牙齿损伤厉害。如果细菌厉害，当然应该立刻把糖从牙齿上去掉，不让细菌有机会把它们变成酸。一般认为，现代人吃糖（碳水）很多，所以还是刷掉遗留的碳水，让细菌无法繁殖产生酸比较靠谱。另外，现代社会因为含氟牙膏的普遍使用，绝大多数的人的牙釉质都很坚固，而很多人要担心牙龈的问题。刷牙很多时候不是为了防止龋齿，而是为了保护牙龈，防止牙结石。
