While we're on the subject, if you brush after meals, you're doing it wrong. Brush first thing in the morning (before your first meal/drink, other than water), and last thing at night (well after your last meal). Plaque acid is at its lowest, so this approach results in the least damage to enamel from brushing. (Amongst other reasons.) For a similar reason, only have a thorough brush in the morning, and a mild brush in the evening.
