Cavity prevention is essential for maintaining good oral health. It involves practices that help protect teeth from decay caused by bacteria. Regular brushing with fluoride toothpaste, flossing, and routine dental check-ups are key components. Fluoride strengthens tooth enamel, making it more resistant to acid attacks from food and drinks. Additionally, a balanced diet low in sugary snacks and drinks can significantly reduce the risk of cavities. Foods high in calcium and phosphorus, like dairy products, can also support strong teeth. Staying hydrated and drinking plenty of water helps wash away food particles and bacteria, further aiding in cavity prevention.
