Brushing your teeth right after a meal may not be the good habit you
think it is.
Research suggests that the exposure to acidic food and drinks during meals softens the enamel of your teeth. Brushing your teeth immediately after consuming acidic foods and drinks increases the chance of enamel erosion.
Therefore, to help prevent dental erosion, it is recommended you avoid brushing for at least 60 minutes after eating or drinking acidic foods or drinks.
