Some people get into a routine of brushing then flossing. The problem with this sequence is that any food, plaque, and bacteria released by flossing from in between your teeth remains in your mouth until the next time you brush.
However, when you floss and then brush, the brushing action removes these released particles from the mouth. As a result, there’s less dental plaque in your mouth, and you’ll have a lower risk of developing gum disease.
The fluoride in your toothpaste is also better able to do its job in protecting your teeth when particles are removed first, noted a small 2018 studyTrusted Source.
Gum disease, also called periodontal disease, is a mouth infection that destroys the soft tissue and bones that support your teeth. Gum disease occurs when there’s too much bacteria on the surface of the teeth.
Because plaque is a primary cause of gum disease, it’s important to floss and brush each day. Plaque usually hardens on the teeth within 24 to 36 hours. If you floss your teeth regularly, and then brush afterwards, plaque usually will not harden on your teeth.
After flossing and brushing, don’t forget to spit out any remaining toothpaste in your mouth. But you shouldn’t rinse your mouth. This likely comes as a surprise since many people have been conditioned to rinse out their mouth with water or mouthwash after brushing.
