What causes swollen gums
Gum swelling most often reflects inflammation of the gingiva around plaque and tartar.
The short answer
Gum swelling most often reflects inflammation of the gingiva around plaque and tartar. Other causes include food trapped between teeth, vigorous brushing, ill-fitting restorations, hormonal changes, medicines, and a dental abscess.
What does swelling of the gums mean by itself?
The swelling is a change in soft tissue, not a diagnosis by itself. Color, tenderness, bleeding, duration, and whether one tooth or many areas are involved help narrow the cause.
What can you do now for swollen gums?
Brush gently with a soft toothbrush, clean between teeth with floss or an interdental brush, and rinse with water after food becomes trapped. Do not puncture a swelling.
When do swollen gums require a dental assessment?
See a dentist if swelling lasts, recurs, bleeds easily, or is accompanied by pain, bad taste, looseness, or pus. Facial swelling, fever, or trouble swallowing or breathing needs urgent attention.
What should you ask about the cause of swollen gums?
Ask whether the swelling is gingivitis, periodontal disease, trauma, a trapped object, a medicine effect, or an abscess, and what examination or X-ray is needed.
Frequently asked questions
Can this be diagnosed from one symptom alone?
Usually not. Location, duration, examination findings, and sometimes imaging determine the diagnosis.
What should I do while arranging care?
Use gentle oral hygiene, avoid aggravating the area, and seek prompt help for worsening pain, swelling, or functional difficulty.
