Why does my dental floss stink?

If your dental floss has a foul smell, it may be due to the accumulation of bacteria, food particles, and other debris that have been left behind in between your teeth and gums. This can happen when you don't floss regularly or when you don't floss properly.

When you floss, you should use a fresh section of floss for each tooth, and you should gently scrape the floss against the sides of your teeth and under your gum line. This will help remove any food particles and bacteria that may be trapped between your teeth.

If you're flossing regularly and still experiencing a foul smell, it may be due to an underlying dental problem, such as gum disease or tooth decay. These conditions can cause a persistent bad odor in your mouth, even if you practice good oral hygiene habits.

To prevent your dental floss from smelling bad, you should floss at least once a day and make sure to use proper flossing techniques. If you continue to experience a foul smell despite your best efforts, you should consult with your dentist to rule out any underlying dental problems that may be contributing to the issue.
