Did you know brushing your teeth immediately after acidic foods or drinks isn’t good for your teeth? Things that contain acid like orange juice, lemon or soda can erase your enamel, make your teeth sensitive and darken your teeth. Brushing too soon may damage enamel while it’s in its weakened state. Wait 30 minutes before brushing to help protect the enamel and rid your smile of bad bacteria. Flossing is just as important. It removes 40% of sticky bacteria and plaque hiding between your teeth.
