Gum blood swelling overview
Bleeding and swollen gums commonly reflect inflammation from plaque, but a painful or rapidly worsening swelling needs prompt dental assessment.
The short answer
Bleeding and swollen gums most often indicate inflamed gingiva, but a localized swelling can also signal a tooth or periodontal infection.
What can cause a lump beside one tooth?
Plaque can cause red, edematous gingiva, while a lump beside one tooth may arise from a deep pocket, root infection, trapped food, trauma, or eruption.
How can you care for bleeding swollen gums now?
Brush gently and clean between teeth if possible. Do not squeeze the swelling or place heat, alcohol, or irritants on it.
When do swollen gums need urgent dental care?
Urgent care is needed for facial swelling, fever, pus, severe pain, or difficulty opening the mouth, breathing, or swallowing.
What should the dentist check as the source?
Ask whether the source is the gum, pulp, periodontal pocket, or erupting tooth, and whether drainage, cleaning, or tooth treatment is needed.
Frequently asked questions
What is the main thing to know?
Bleeding and swollen gums most often indicate inflamed gingiva, but a localized swelling can also signal a tooth or periodontal infection.
Can home care replace an examination?
No. Home care may reduce irritation or plaque, but persistent, worsening, or unexplained symptoms need clinical assessment.
