16. Eating Potato Chips
There are plenty of foods that you know are bad for your teeth. Anything with high levels of sugar (i.e. cookies, cake, donuts, brownies, ice cream, even ketchup, and barbecue sauce) leaves teeth susceptible to bacteria showing up and feasting on the sugar that is stuck to them. You know that you should brush and floss after eating foods with sugar, but what about savory foods, like potato chips? As far as teeth are concerned, the problem with potato chips is that they have a high level of starch. After all, potatoes are starch, and potato chips are just potatoes that are cut, fried, and well-seasoned. The starch in chips can easily get stuck in the crevices between your teeth and become a breeding ground for the bacteria that cause enamel breakdown and cavities. Further, starch breaks down into sugar, and we all know the harm that sugar poses to your teeth.
