Flossing removes small particles of food stuck between your teeth that your toothbrush can’t reach. Those particles of food are also food for the bacteria that live in your mouth. Your mouth bacteria will eat those particles and secrete acids as a byproduct. Those acids eat away at your tooth enamel and that’s how cavities form. The bacteria can also cause gum inflammation and infection, which can lead to permanent destruction of gum tissue and permanent bone loss, ultimately leading to tooth loss.
