Is it good to floss more than once a day?

Flossing more than once a day can be beneficial, especially if you have braces, gum disease, or a lot of dental work. However, for most people, once a day is sufficient to remove plaque and food particles from between teeth. Over-flossing can potentially irritate the gums and lead to damage if done too aggressively. It's best to consult your dentist for personalized advice on your oral hygiene routine.
