Gum bleeding causes and next steps
Bleeding gums most often reflect inflamed gum tissue, but persistent bleeding can also signal periodontal disease, trauma, or a medical factor.
The short answer
Bleeding from the gums commonly indicates inflammation caused by plaque at the gumline, although other local and medical causes are possible.

Why does plaque make the gums red and prone to bleeding?
Plaque irritates gingiva, making it red, swollen, and prone to bleed. Other causes include brushing injury, ill-fitting appliances, gum infection, periodontal pockets, smoking, and medicines or conditions affecting clotting.
How can you care for bleeding gums at home?
Brush gently with fluoride toothpaste and clean between teeth daily. Do not stop cleaning because of light bleeding, but arrange an examination.
When does gum bleeding need prompt dental care?
Seek care when bleeding is heavy, spontaneous, persistent, or paired with swelling, loose teeth, pus, or fever.
What should your dentist check when gums bleed?
Ask whether the bleeding is gingivitis, periodontal disease, trauma, or another cause, and whether pocket measurement or periodontal treatment is needed.
Frequently asked questions
Why do gums bleed when I floss?
Inflamed tissue may bleed when plaque is disturbed, but regular gentle cleaning and assessment remain important.
Should I avoid flossing?
Usually no. Gentle cleaning helps remove plaque, but pain, swelling, or heavy bleeding warrants prompt advice.
