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.
I've read that it's not good to brush right after any meal. The acids and sugars soften the enamel, then when you brush it can wear down the enamel. So brush before breakfast or a while after. I asked my dentist about this and they said that rinsing your mouth with water after a meal clears the acid.
