Brushing your teeth after eating can ruin your teeth
Mervyn Druian, of the London Centre for Cosmetic Dentistry, told the Daily Mail that encouraging kids to brush their teeth right after eating breakfast is the worst thing you can do.
“Eating food causes a build-up of acid in the mouth, which softens the enamel temporarily — and drinking fruit juice makes the mouth even more acidic.
If you brush straight afterwards, you are brushing away soft enamel. I always recommend brushing teeth as soon as you wake up, and not again until you’re about to go to bed.”
Michaela O’Neill, president of the British Society of Dental Hygiene and Therapy, adds that you should spit out your toothpaste following brushing, but rinsing will remove the fluoride from your mouth. She also discourages mouthwash for the same reason.
“It’s also a good idea to not eat or drink for 30 minutes after using fluoride toothpaste.”
Both experts recommend chewing gum inbetween meals for around twenty minutes, and to avoid regular snacking, which keeps your teeth in a permanent “acid bath”.
“Every time you eat, acid levels in the mouth go up and take 40 minutes to get back to normal. If you keep grazing, your acid levels stay high, causing damage to your teeth.”
