Bleeding when you floss, especially after a gap of days or weeks between flossing, is usually a sign of gingivitis — early, reversible gum inflammation caused by plaque buildup along the gumline, not a sign you’re flossing too hard or damaging your gums. The fix is more flossing, not less: daily flossing for one to two weeks typically resolves the bleeding as the gum tissue heals and inflammation subsides. Bleeding that persists for several weeks of consistent daily flossing, or that’s accompanied by loose teeth, receding gums, or persistent bad breath, can indicate the gum disease has progressed to periodontitis, which involves bone loss around the teeth and needs professional treatment rather than better home care alone. A regular checkup is the only reliable way to tell the difference.
