When brushing your teeth isn't a good idea

Although it's been common knowledge for a while that fruit juices and smoothies are not all that good for your teeth (because they typically contain lots of sugar and acid), some dentists are now telling patients NOT to brush their teeth after indulging in a fruity treat.

The reason, they say, is because brushing hastens the erosion of the enamel that has has been weakened by the acidic juice. Instead, they are urging fruit fans to brush before they have their drink.

I guess that drinking a glass of water, and, in the process swilling out the sugary residue, may be the best way to go.
