Question: what does it mean if your gums bleed when you floss?
Answer: Bleeding gums may be a sign of poor dental hygiene. Gums become inflamed and bleed when there's a buildup of plaque along the gum line. Plaque is a sticky film containing bacteria that covers your teeth and gums. And if you don't brush or floss enough, the bacteria can spread and cause tooth decay or gum disease.
