When it comes to tooth decay, it’s important to know the main culprit – acid. Acid is what eats away at our enamel and causes cavities.
Acid can enter our mouths in one of two ways: either directly through what we eat (citrus fruits, for example), or as a byproduct when oral bacteria consume the sugars that we eat.
Ultimately, a simple way to identify foods that cause tooth decay is to ask whether it’s acidic or sweet/starchy.
Acidic foods include things like citrus fruits, tomatoes, vinegar, kombucha and sour candy.
Sweet/starchy foods include things like candy, soda or sugar-sweetened beverages, fruit, bread, cereal, pasta and crackers.
The longer these things interact with your teeth, the greater the chance for tooth decay to occur.
For example, sipping on soda throughout the day, or chewing a gooey caramel treat, increases the amount of sugar that coat your teeth. Bacteria love to feast on this sugar, creating an acidic environment and putting your teeth at risk for decay.
