3. Brushing at the Wrong Times
You were always told to brush after every meal, right? Well, the truth is a bit more complicated than that.
While certain foods and drinks—especially ones high in refined carbohydrates—spur the growth of bacteria in your mouth in as little as 20 minutes, requiring immediate brushing afterward, if you brush after other foods, especially acidic ones, you might be doing more damage than good.
Brushing your teeth immediately after consuming acidic foods can damage tooth enamel. Acidic foods weaken tooth enamel for about 30 minutes after eating, so brushing up to 30 minutes after meals will actually strip away the enamel in its weakened state, leading to an increased susceptibility to cavities.
This is why I like to say it’s better to brush and floss before breakfast, rather than after!
Instead of brushing after eating acidic foods, swish with water or chew gum to neutralize acid in the mouth. Once 30 minutes have passed, you’re free to brush.
And as for the debate over whether to brush or floss first, it isn’t actually all that important. While there’s a case for both side, what matters is that you’re doing both.
