Regular teeth cleaning is crucial for overall health. Plaque buildup on teeth is the primary cause of tooth decay and gum disease, which can be avoided by brushing teeth twice daily for at least two minutes with fluoride-based toothpaste, flossing daily, and using mouthwash. Toothbrushes come in different shapes, sizes, and bristle types, and toothpaste has several types, such as fluoride, whitening, natural, and desensitizing. Brushing too hard damages enamel and causes sensitivity. Consistent oral hygiene habits not only protect against tooth decay and bad breath but also save money on dental procedures, and visiting the dentist regularly is crucial.
