Bleeding when brushing or cleaning between teeth can be a sign of gum inflammation, often associated with plaque build-up. It should not be ignored, especially when it persists or occurs with swelling, tenderness or bad breath.
Possible causes include plaque around the gumline, gingivitis, changes in oral hygiene habits, irritation from brushing too hard or other oral or general health factors. Only a dental professional can assess the cause in an individual case.
If bleeding is frequent, persistent or accompanied by gum recession, loose teeth, pain or swelling, arrange a dental assessment.
Brush gently twice a day with a soft toothbrush and fluoride toothpaste, and clean between teeth daily using an appropriate method. Avoid aggressive brushing. If a particular product or technique causes irritation, ask your dental team for advice.
Home care supports gum health but does not replace professional assessment or treatment when gum disease is present.
Arrange an appointment if bleeding continues, worsens or occurs alongside swelling, persistent bad breath or tooth mobility. Seek urgent help for heavy bleeding that does not stop or swelling that affects breathing or swallowing.
Professional cleaning can remove deposits that brushing cannot remove, where indicated. The dentist or hygienist can also assess gum health and advise whether further gum treatment or a tailored maintenance plan is needed.
