Mouth bleeds when brushing teeth
Gums that bleed during brushing are commonly inflamed by plaque, but bleeding can also reflect trauma, gum disease, or another medical factor.
Why do my gums bleed when I brush my teeth?
Gums that bleed during brushing are commonly inflamed by plaque, but bleeding can also reflect trauma, gum disease, or another medical factor.
How does plaque make gum tissue bleed?
Plaque at the gum margin triggers gingival inflammation, making the tissue red, swollen, tender, and more likely to bleed. A hard brush, forceful technique, new flossing, ill-fitting dental work, smoking, and some medicines can also contribute.
What should I do to clean bleeding gums gently?
Use a soft toothbrush with gentle small motions along the gumline and clean between the teeth daily. A dental professional may remove calculus, measure gum pockets, and treat cavities or periodontal disease if present.
When does bleeding during brushing need examination?
Arrange a dental examination if bleeding continues, gums recede, teeth loosen, or there is persistent bad breath or pus. Seek urgent help for heavy bleeding, facial swelling, fever, or trouble swallowing or breathing.
What should I ask about the cause of gum bleeding?
Ask whether the bleeding is gingivitis, periodontitis, trauma, or a medicine-related issue. Ask which brush, interdental method, and professional cleaning plan fit your gums.
