刷牙可以保护牙齿,那么,我们该不该一吃过饭就马上给牙齿做个全面清洁呢?实际上,这样做会伤害牙齿。因为如果你在进食时吃到酸性食物,酸性食物在与牙齿接触后,一段时间里就会软化牙齿表面的牙釉质。这时如果马上刷牙或者食用坚硬的食物,牙齿就会被加快磨损,后齿的啮合部分和前牙的尖部尤其容易受伤。 Brushing your teeth helps to protect your teeth, so should we clean the teeth as soon as we have eaten? In fact, doing so can hurt our teeth. Because if you eat acidic foods while eating, acidic foods soften the tooth enamel on the teeth for some time after they come into contact with the teeth. At this point if you brush your teeth or eat hard food immediately, the teeth will be accelerated wear and tear, after the tooth meshing part and the tip of the anterior teeth particularly vulnerable.
