About a fifth of seven to ten years olds drink nearly ten cans of fizzy soft drink a week. This can play havoc with their teeth as the sugars and acids attack the enamel. The exact damage depends on how you drink: if you swig from the can, letting it pool at the back of your mouth, then your molars get it; if you sip through your front teeth then they suffer.
US scientist have decided that the safest way to drink the stuff is through a straw into the back of the mouth, minimizing the length of time it’s in contact with your teeth. It’s also a good idea to rinse your mouth with water afterwards.
