Why are my gums bleeding suddenly
Sudden gum bleeding often comes from inflamed gingival tissue, but trauma, a new medicine, infection, or a bleeding disorder can also contribute.
The short answer
Bleeding from the gingiva usually reflects plaque irritating the gum margin, although vigorous brushing, flossing injury, mouth ulcers, medicines, or a broader medical problem can also cause it.
Why does gingivitis make gums bleed when disturbed?
Gingivitis makes the gum margin red, swollen, and prone to bleeding when plaque is disturbed. A dentist checks the gum tissues, deposits, pockets, teeth, and medical history to separate local irritation from a wider cause.
How should you clean gums that suddenly bleed?
Use a soft brush with gentle pressure and clean between the teeth carefully rather than stopping hygiene. Note when bleeding began, which sites bleed, recent dental work, new medicines, pregnancy, bruising, or nosebleeds.
When does sudden gum bleeding need prompt care?
Seek prompt dental care for bleeding that persists, recurs without brushing, follows facial trauma, or comes with swelling, fever, loose teeth, or marked pain. Seek urgent medical help for heavy bleeding, faintness, or widespread unexplained bruising.
What should your dentist investigate about sudden bleeding?
Ask whether the pattern fits gingivitis, periodontitis, trauma, or a medicine effect, and whether you need periodontal measurements, radiographs, a cleaning, or medical assessment.
Frequently asked questions
Is bleeding after flossing normal?
Tender inflamed gums may bleed when flossing begins, but continued bleeding deserves an examination and improved technique.
What does a dentist check?
The dentist examines gum colour, swelling, plaque, calculus, pocket depth, tooth mobility, and relevant health history.
