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.
Your brush shouldn't travel across the gums. You should always brush your tongue, or buy a tongue scraper. It should take two to three minutes to do a thorough job. Don't brush for half an hour after eating, to give your saliva time to do its job and neutralise the acid caused by eating and drinking.
