I'm a bit fussy about my teeth. I brush at least twice a day and I always floss and use an interdental brush after brushing. And I've always brushed my teeth within a few minutes of finishing my breakfast... until today that is, when I read that:
"The worst thing that you could do is to brush your teeth straight after eating or drinking something acidic such as citrus fruit or fruit juice, because the acid actually softens the top layer of your teeth and by brushing you are actually scrubbing that bit off. Always wait half an hour before brushing so that your teeth have remineralised."
