Why blood comes from gums
Gums commonly bleed when plaque irritates the gingival margin, but repeated bleeding can indicate gum disease or another problem needing assessment.
The short answer
Bleeding during brushing often reflects inflamed gums from plaque, although persistent or spontaneous bleeding needs a dental examination.
What is the direct answer?
What does this question mean?
The gingiva becomes red, swollen, and more fragile when bacterial plaque remains around the gum margin. Bleeding can also relate to calculus, trauma from brushing, infection, medication effects, or a medical bleeding disorder.
What can you do next?
Clean gently along the gumline twice daily with a soft brush and clean between teeth with floss or interdental brushes. Do not stop cleaning because of a small amount of bleeding, but arrange professional removal of calculus and a gum assessment if it continues.
When should you seek dental care?
Seek prompt care for heavy or spontaneous bleeding, facial swelling, fever, loose teeth, ulcers that do not heal, or bleeding elsewhere in the body. Mention medicines and medical conditions at the appointment.
What should you ask the dentist?
Ask whether you have gingivitis or periodontitis, whether calculus is present below the gumline, and which interdental cleaning size and technique are appropriate.
Frequently asked questions
Should I keep brushing bleeding gums?
Gentle cleaning usually helps remove the plaque causing inflammation. Avoid force and arrange an examination if bleeding persists.
Can flossing cause bleeding?
Incorrect technique or inflamed tissue can cause bleeding. A dental professional can demonstrate a suitable method.
