Getting blood from teeth
Blood seen while brushing usually comes from inflamed gum tissue, not from inside the tooth, and it should be investigated if it keeps happening.
The short answer
Blood seen while brushing usually comes from inflamed gum tissue, not from inside the tooth, and it should be investigated if it keeps happening. Plaque bacteria can trigger gingivitis at the gum margin; tartar, vigorous brushing, appliances, gum disease, and local trauma can also contribute. A dentist checks gum pockets, tooth surfaces, deposits, and medical factors.
What can irritate the gum margin and cause bleeding?
Plaque bacteria can trigger gingivitis at the gum margin; tartar, vigorous brushing, appliances, gum disease, and local trauma can also contribute. A dentist checks gum pockets, tooth surfaces, deposits, and medical factors.
How can you brush and clean between teeth safely?
Brush gently twice daily with a soft brush and clean between the teeth every day. Do not stop cleaning the bleeding area, but arrange an examination if bleeding continues.
Which bleeding symptoms need prompt dental attention?
Seek prompt care for spontaneous bleeding, loose teeth, pus, facial swelling, fever, or bleeding that is difficult to control. Injury-related bleeding may need local examination.
What cause and cleaning method should you discuss?
Ask whether this is gingivitis or deeper periodontal disease, whether tartar is present, and which cleaning technique fits your gums.
