Bleeding teeth
Bleeding usually comes from inflamed gums, but trauma, infection, medicines, or a bleeding disorder can also be involved.
The short answer
Bleeding usually comes from inflamed gums, but trauma, infection, medicines, or a bleeding disorder can also be involved. Teeth themselves do not bleed; blood usually comes from the gingiva around them. Plaque-related gingivitis is common, but a cut, abscess, vigorous brushing, dental treatment, medicines, or a condition affecting clotting can also cause oral bleeding.
What does healthy gum tissue normally look and feel like?
Healthy gum tissue is firm and closely adapted to the tooth. Inflammation makes the gum margin swollen and fragile, so it may bleed during brushing, flossing, or eating, while bleeding from one isolated spot may point to trapped food, trauma, or a local lesion.
How should you clean teeth when the gums are bleeding?
Continue gentle brushing with a soft brush and clean between the teeth rather than avoiding the bleeding area. Note where, when, and how much it bleeds, review new medicines with a clinician, and use clean gauze with steady pressure for a fresh injury.
When should recurring tooth-area bleeding be examined?
Book dental care for bleeding that persists, recurs, or comes with swollen gums, loose teeth, bad breath, pain, or pus. Seek urgent help for heavy bleeding that does not stop with pressure, facial swelling, fever, faintness, or breathing difficulty.
What should you ask about inflamed or tartar-covered gums?
Ask which gum areas are inflamed, whether tartar is present below the gumline, and whether you need professional cleaning or periodontal treatment. Mention pregnancy, medical conditions, and every medicine or supplement you use.
Frequently asked questions
Should I stop brushing bleeding gums?
No. Use a soft brush gently and clean the area, because plaque left behind can maintain inflammation.
When is mouth bleeding an emergency?
Heavy or persistent bleeding, facial swelling, fever, faintness, or breathing difficulty needs urgent assessment.
