Why are my teeth bleeding when i brush them
Bleeding during brushing usually means inflamed gums, but trauma, calculus, gum disease, or a local dental problem can also be involved.
The short answer
Gums commonly bleed during brushing when plaque has inflamed the gingiva, but repeated bleeding can also reflect calculus, recession, infection, or brushing trauma.
Why does the blood usually come from the gums?
The teeth themselves do not usually bleed; the blood generally comes from the gingiva at the gum margin. Plaque bacteria trigger inflammation, making the tissue red, swollen, and more likely to bleed when touched.
How should I clean my teeth when brushing causes bleeding?
Continue gentle cleaning with a soft brush and clean between the teeth, rather than avoiding the bleeding area. Arrange professional removal of calculus if deposits are present, since hard deposits cannot be removed with brushing.
When does brushing-related bleeding need dental examination?
Book an examination when bleeding is frequent, localized, worsening, or accompanied by swelling, pus, bad breath, pain, or loose teeth. Urgent care is needed for uncontrolled bleeding, facial swelling, fever, or difficulty swallowing.
What should I ask about repeated bleeding while brushing?
Ask whether the bleeding is gingivitis or periodontitis, where plaque and calculus are located, and whether gum measurements or radiographs are needed. Ask for a brushing and interdental-cleaning demonstration.
Frequently asked questions
Should I stop brushing bleeding gums?
No. Brush gently and clean between the teeth while arranging an examination if the bleeding persists.
Can bleeding gums mean gum disease?
Yes. An examination distinguishes reversible gingivitis from deeper periodontal disease and other local causes.
