Inside is a fizzy drink that tastes very much like Coca-Cola.

里面装有充气饮料，味道很像可口可乐。

Encouraging people to drink fewer fizzy drinks, however, is fiendishly difficult.

然而，鼓励人们尽量少喝碳酸饮料却出奇的难。

Brushing within 30 minutes of a big meal of fizzy drink like cola, can lead to worse damage.

如果喝了可乐等起泡饮料，在餐后30分钟内立即刷牙，更容易损害牙齿。

So if you have a can of fizzy drink and sip it all day long, then the acid in your mouth will be under constant attack.

这样一来，如果你一整天都在小口啜饮一罐饮料，就等于那些酸性物质一直在攻击你的牙齿。

Wait at least an hour after a meal or fizzy drink before brushing - this will give your saliva a chance to neutralise the acid.

餐后或者喝起泡饮料后，最好等半小时再刷牙——这就能给唾液留出时间来中和酸度。
