Why do my gums swell and bleed
Swollen, bleeding gums most often reflect plaque-related inflammation, but persistent symptoms can indicate deeper gum disease.
The short answer
Gums commonly swell and bleed when plaque irritates the gingival margin, but persistent bleeding can also reflect calculus, periodontal disease, trauma, medication effects, or infection. Bleeding is a sign to investigate, not a reason to stop gentle cleaning.
What is the direct answer?
What does this question mean?
Gingivitis affects the superficial gum margin, while periodontitis can damage the fibres and bone supporting teeth. A dentist checks colour, swelling, bleeding on probing, pocket depth, recession, tooth looseness, and plaque or calculus.
What can you do next?
Brush twice daily with a soft brush and clean between teeth with floss or an interdental brush that fits. Arrange professional removal of calculus, because hardened calculus cannot be brushed away at home.
When should you seek dental care?
Book an examination if bleeding continues despite careful cleaning, or if gums are painful, receding, or causing bad breath. Seek urgent care for facial swelling, fever, pus, or uncontrolled bleeding.
What should you ask the dentist?
Ask whether the findings fit gingivitis or periodontitis, whether periodontal measurements and X-rays are needed, and which interdental tool fits each space. Ask how treatment will remove plaque and calculus below the gumline.
Frequently asked questions
Should bleeding make me stop flossing?
No. Gentle, consistent plaque removal is usually needed, although painful or heavy bleeding should be assessed.
Can swollen gums grow back over a tooth?
Inflammatory swelling can partly cover a tooth, while an erupting tooth, medication, or a local infection can create a more specific enlargement.
