You should know, however, that brushing your teeth after eating can sometimes affect your tooth enamel. According to the Mayo Clinic, 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.
This softens the enamel on your teeth, so if you brush immediately after eating you can damage the enamel. Wait at least 30 minutes after eating to brush your teeth and, in the meantime, rinse with water to prevent stains. Whitening toothpastes can remove stains, but they won't prevent them.
