When you eat sugar, the bacteria in your mouth feed on it and produce acid. This acid slowly wears down your tooth enamel, the protective outer layer of your teeth, leading to cavities, sensitivity, and tooth decay. It’s not just obvious sugar like chocolates and sodas; hidden sugars in processed foods like breakfast cereals, ketchup, energy drinks, and even so-called “healthy” granola bars can be just as harmful. Constant snacking on such foods gives bacteria more time to create acid, increasing the risk of gum disease, bad breath, and long-term dental problems. You can still enjoy sweets in moderation by taking some smart steps. Rinse your mouth or drink water after eating sugary items, brush twice a day with a fluoride toothpaste, floss regularly, and never skip your dental check-ups. Chewing sugar-free gum can also help stimulate saliva, which naturally neutralizes acid.
