How do you prevent black teeth?

To prevent black teeth, maintain a consistent oral hygiene routine that includes brushing twice a day with fluoride toothpaste and flossing daily. Regular dental check-ups and cleanings are essential for early detection and treatment of issues like tooth decay or gum disease. Additionally, limit consumption of stain-causing foods and beverages, such as coffee, tea, and red wine, and avoid tobacco products. Staying hydrated and rinsing your mouth after consuming acidic or sugary foods can also help protect your teeth.
