Cavities remain the leading oral health problem throughout the world, affecting children and adults. While oral hygiene and daily lifestyle habits can be to blame, a few of the more widely known culprits are sugar and starch. But did you know there are certain foods that are equally damaging to teeth? Keep reading to discover the surprising cavity-causing foods you may be unaware of.

Citrus Foods = Enamel Erosion

Oranges, lemons, limes, and other citrus foods may taste good, but they can have a damaging effect on your teeth.

These fruits are highly acidic, which means that when exposed to tooth enamel, the acids can begin to erode this top layer. Over time, it will break down and increase your risk of tooth decay, which can lead to cavities.

Although they contain beneficial amounts of vitamin C, consume them in moderation alongside a glass of water. This keeps your salivary glands working and flushing out your mouth, all while neutralizing the acids to prevent erosion.

Pasta Sauce = Problems For Your Teeth

It might seem as if pasta sauce is a problem because it can stain your teeth, but the real issue is its hidden sugar content. Many are also acidic, so you have to be careful about possible enamel erosion.

When combined with bacteria, sugar and acid can cause decay and gum disease to develop.

However, if you choose to top your noodles with pesto or alfredo sauce, you may be pleased to learn that they contain less sugar, making them healthier options for your body and smile.

Dried Fruits = Damaged Enamel

Many individuals are under the impression that dried fruits are just as healthy as the fresh variety. The truth is that not only are they sticky, often adhering to the chewing surfaces of teeth, but they’re also high in sugar. When consumed regularly, they can begin to erode tooth enamel and increase your risk of tooth decay. Before you know it, you have one or more cavities that need repair.

Opt for fresh fruits that not only have natural sugars but also encourage saliva production. This flushes harmful bacteria out of your mouth and neutralizes acids.

Before you pick up a piece of food, think about what it might do to your teeth. When consumed in moderation and when making smart choices, you can keep your pearly whites cavity-free.
