Bleeding gums first aid and triage
Bleeding gums often reflect inflamed gum tissue, but persistent, heavy, or spontaneous bleeding needs a dental examination.
The short answer
Bleeding gums commonly occur when plaque irritates the gum margin and causes inflammation, especially when cleaning has been inconsistent or the tissues are tender. Use a soft toothbrush and gentle daily cleaning, but arrange a dental examination if bleeding persists, occurs without brushing, or comes with swelling, pain, loose teeth, or a bad taste.
Where does blood from inflamed gums usually come from?
The blood usually comes from small inflamed vessels in the gingiva, the gum tissue around the teeth. Causes can include plaque-related gingivitis, periodontitis, trauma from brushing or flossing, a poorly fitting appliance, mouth sores, or a medical or medication-related bleeding tendency.
What should you do when your gums bleed during cleaning?
Brush twice daily with a soft brush using light pressure at the gumline, clean between the teeth with floss or an interdental brush, and avoid picking at the bleeding area. A dentist or hygienist may remove hardened calculus and measure gum pockets; treatment then addresses the cause rather than merely stopping the blood.
When does bleeding gums require a dental examination?
Book an examination for bleeding that continues after several days of careful cleaning, returns often, or is accompanied by gum recession, swelling, pus, persistent bad breath, pain, or tooth mobility. Seek urgent medical help for uncontrolled bleeding, faintness, or swelling that affects breathing or swallowing.
What conditions could be causing your gum bleeding?
Ask whether the bleeding is from gingivitis, periodontitis, trauma, an appliance, or another condition. Ask for a gum examination, pocket measurements when indicated, a cleaning plan, and advice about any medicines or medical conditions that could affect bleeding.
Frequently asked questions
Should I stop brushing when my gums bleed?
Usually no; use a soft brush and gentle pressure, because avoiding the gumline can leave plaque in place.
Can flossing cause bleeding?
Floss can injure the gum if forced or snapped, but repeated bleeding may also signal inflammation that needs examination.
