Dental floss is a thin, flexible string designed to clean between your teeth. It helps remove food particles and plaque that a toothbrush might miss, promoting better oral hygiene. Using dental floss regularly can prevent cavities and gum disease, making it an essential part of your daily dental care routine. To use dental floss, you simply take a piece about 18 inches long, wrap it around your fingers, and gently slide it between your teeth. It's important to be careful and not snap the floss, as this can hurt your gums. Incorporating dental floss into your routine can lead to a healthier smile!
