Gums bleeding when brushing teeth is usually caused by irritation or inflammation of the gums, often due to plaque buildup. Plaque is a sticky film of bacteria on teeth that, if not removed by regular brushing and flossing, irritates the gums and makes them bleed. This bleeding can be an early sign of gum disease such as gingivitis, which causes swollen, tender, and red gums. Other possible reasons include brushing too hard, using a toothbrush with hard bristles, starting a new flossing routine, or taking certain medications like blood thinners. If gums bleed consistently, it is important to consult a dentist because untreated gum disease can progress to more serious conditions affecting teeth and gums.

Common Causes of Bleeding Gums When Brushing

• Plaque buildup leading to gum irritation and gingivitis
• Brushing too aggressively or with a hard-bristled toothbrush
• Starting or changing flossing or oral care routine
• Medications that affect blood clotting (e.g., blood thinners)
• Gum disease (gingivitis and periodontitis)

What to Do

• Use a soft-bristled toothbrush and brush gently
• Brush teeth twice daily for at least two minutes
• Floss gently daily to remove plaque from between teeth
• Consider antiseptic mouthwash if recommended by a dentist
• Schedule a dental check-up to assess and treat any gum issues early

Bleeding gums should not be ignored, as early intervention can prevent more severe gum disease and potential tooth loss.
