Gum swelling bleeding and care
Swollen or bleeding gums often reflect inflammation, but may also involve gum disease, trauma, trapped food, decay, or an abscess.
The short answer
Gingival swelling is an increase in gum tissue fluid and inflammatory cells, while bleeding occurs when delicate inflamed tissue is disturbed during brushing or probing.
What causes swollen gums to bleed during brushing?
Gums that swell or bleed are inflamed until the cause is identified, and the cause may range from plaque irritation to a tooth or gum infection.
What conditions can cause gum swelling and bleeding?
Plaque bacteria can trigger gingivitis at the gum margin; deeper periodontal pockets, a foreign body, ill-fitting dental work, hormonal changes, medicines, and infections can produce similar findings. Swelling around one tooth can indicate a local dental problem.
How can you care for swollen or bleeding gums?
Brush gently with fluoride toothpaste, clean between the teeth, and arrange an examination if bleeding persists or swelling is localized. A dental professional may measure pocket depth, remove calculus, take radiographs, and treat the cause.
Which gum swelling and bleeding signs need urgent care?
Seek prompt care for a painful lump, pus, fever, facial swelling, loose tooth, or swelling that spreads. Breathing or swallowing difficulty is an emergency requiring immediate help.
What should the dentist check when gums swell and bleed?
What will the dentist check? Ask whether the swelling comes from the gum, tooth, wisdom tooth area, or another tissue, and whether you need periodontal measurements, radiographs, cleaning, or urgent treatment.
