How can your teeth be dirty if you floss once a day and brush twice day?

There are a few reasons why your teeth may still be dirty even if you floss once a day and brush twice a day.

* You may not be brushing and flossing properly. Make sure to brush your teeth for at least two minutes, twice a day, and floss your teeth once a day. When brushing, be sure to brush all surfaces of your teeth, including the insides, outsides, and tops. When flossing, be sure to floss between all of your teeth, and don't forget to floss the backs of your molars.

* You may be eating and drinking foods and beverages that stain your teeth. Some foods and beverages, such as coffee, tea, red wine, and berries, can stain your teeth. If you consume these foods and beverages regularly, you may need to brush and floss your teeth more often to prevent staining.

* You may have a medical condition that affects your teeth. Some medical conditions, such as dry mouth, can cause your teeth to become more susceptible to plaque and tartar buildup. If you have a medical condition that affects your teeth, talk to your doctor or dentist about how to manage your oral hygiene.

If you are still experiencing dirty teeth after brushing and flossing properly and avoiding foods and beverages that stain your teeth, you may need to see your dentist for a professional cleaning. Your dentist can remove plaque and tartar buildup that you cannot remove at home, and can recommend additional ways to keep your teeth clean and healthy.
