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.

Brushing during that time will force acid into the pores of your tooth enamel and help to break it down.
