#2 Cleaning Your Teeth Straight After Eating
You might have thought you were doing the right thing by leaning your teeth straight after eating. In fact, it may have even been drummed in to you by your parents that you should do such a thing (and don’t forget to floss!).
The truth is a little different, however. Yes, you should brush your teeth often (and floss) but not straight after you’ve eaten. It’s all about the pH level. Most foods you eat will be fairly acidic, which leaves your chompers a little more vulnerable to damage than they might ordinarily be. So, this is the worst time to be brushing your teeth, on account of the fact that the brushing action could actually ruin your tooth enamel.
All you have to do is wait a half hour or so, and then get brushing (and yeah, flossing too).
