EYE DROPS
眼药水

It sounds unlikely, but anti-inflammatory eye drops can contribute to tooth decay. They are one of a number of drugs — including antidepressants, ibuprofen, antihistamines and blood pressure medications — that cause dry mouth, which means they reduce the production of saliva.

这听上去有些不可思议，但是消炎眼药水的的确确会引起蛀牙。消炎眼药水连同抗抑郁药、镇痛消炎药、抗组胺药和降血压药这些药品都会让你觉得口干，也就是说它们会抑制唾液分泌。

Saliva acts as a barrier, protecting the teeth by neutralising acidic foods such as oranges, and the acid produced by bacteria as they break down foods.

而唾液正像一道保护牙齿的屏障，把橘子等酸性食物以及细菌分解食物产生的酸性物质中和掉。

REDUCE THE RISK: ‘There are gums, lozenges and gels available over the counter specifically for dry mouth that help encourage the production of saliva,’ says Karen. ‘You could also suck sugar-free sweets for the same effect.’

如何补救：凯伦说：“口干的话，口香糖，含片和牙胶都是无需处方就可以买到的，这些东西都有助唾液分泌。也可以呷吧呷吧无糖的甜食，效果是一样的。”
