Brushing, flossing, using mouthwash and having regular checkups are all vitally important for good teeth, but its important not to overlook the power of a solid diet in dental health.

　　刷牙、用牙线、漱口水、常规口腔检查都对牙齿健康有好处，重视固体饮食的习惯也非常重要。

　　And even though we all know things like fizzy drinks, sweets or lollies and chocolate are bad for our pearly whites, there are more surprising foods that also contribute to bad teeth.

　　我们都知道碳酸饮料、糖果和巧克力对牙齿有伤害，除此之外，还有很多事物也对口腔没什么好处。

　　Dr Peter Chuang from the Australian Dental Association Oral Health Committee recently revealed the unexpected foods that are ruining your white smile.

　　澳大利亚口腔健康协会的皮特医生最近列举了一些对口腔健康有害的食物，非常出人意料。

　　It's hard to debate the fact that fruit is good for you. But is your daily lemon-infused water, orange and grapefruit doing much good for your teeth?

　　很难说水果对人是不是有益的，但是柠檬水、橘子、葡萄真的对牙齿有好处吗?

　　'Oranges and other citrus fruits such as lemons and grapefruits contain high levels of citric acid, which can lead to an increased risk of enamel erosion and teeth sensitivity,' Dr Chuang told Women's Health.

　　皮特医生告诉媒体《Women's Health》：“橘子和其他像柠檬、葡萄这样圆圆的水果含有大量柠檬酸，会造成牙齿表层腐蚀和牙齿敏感。”

　　In their place, he recommends swapping them out for an apple or a banana, which both contain less acid.

　　皮特医生推荐把这些水果换成苹果或香蕉，这两种水果柠檬酸含量少一些。

　　Pasta

　　意大利面

　　Your regular pasta habit isn't anything to be worried about, right? But if they are laced in Napoli or any tomato-based sauce, you might want to be careful - as Dr Chuang warns that both of these are highly acidic.

　　你是不是对自己热爱意大利面的事一点都不担心?但是如果上面加的是那不勒斯或者番茄酱，可能要注意一下了。皮特医生说这两种酱里都含着大量的酸。

　　He warned that canned tomatoes - which are typically used to make pasta sauces - are also much higher in acid than normal tomatoes.

　　皮特医生还说通常用来搭配意大利面的罐装番茄酱比一般的番茄含有更多的酸。

　　If you want to make your pasta better for your teeth, opt for natural-based sauces or a simple olive oil base.

　　要是想吃对口腔好一些的意大利面，就选用天然酱料或者用橄榄油打底吧。

　　Popcorn

　　爆米花

　　It's not just acidic foods you need to worry about. The dentist pointed out that hard and crunchy foods 'also place great strains on your teeth, increasing the risk of fracture'.

　　除了含酸的食物，皮特医生说硬、脆的食物“给牙齿带来了太大的负担，可能会碎”。

　　One such food among these is popcorn, which can often contain unpopped kernels among the popped ones - and these can crack your teeth.

　　爆米花就是其中一种，通常里面总有没爆好的玉米粒，可能会震碎牙齿。
