Dental caries begins when bacteria in your mouth feed on sugars and produce acids. These acids weaken the enamel, leading to cavities over time. Early stages may have no symptoms, but as decay progresses, sensitivity and pain can occur. Prevent it by brushing twice daily with fluoride toothpaste, flossing, reducing sugar intake, and visiting your dentist regularly.
