Flossing is an important dental hygiene practice that involves using a thin piece of string, called dental floss, to clean between your teeth. This helps remove food particles and plaque that a toothbrush might miss. By flossing regularly, you can prevent cavities and gum disease, keeping your mouth healthy and fresh. To floss properly, take about 18 inches of floss and wrap the ends around your fingers. Gently slide the floss between your teeth, making a C-shape around each tooth. Be careful not to snap the floss, as this can hurt your gums. Aim to floss at least once a day for the best results!
