Swelling in gums with pain
Painful gum swelling can come from plaque-related inflammation, trapped food, a gum abscess, a tooth infection, trauma, or an erupting tooth.
The short answer
Painful swelling may be limited to the gum around one tooth or may involve a wider area. Possible causes include gingivitis, periodontal infection, an abscess from the tooth or gum, trapped food, a sharp edge, trauma, or inflammation around an erupting tooth.
How will a dentist investigate painful gum swelling?
The dentist looks for redness, a pocket, pus, decay, a cracked tooth, tooth mobility, and tenderness, then may probe the gums and take an X-ray. Treatment is directed at the source and can include professional cleaning, drainage, a filling, root canal treatment, periodontal care, or extraction when necessary.
What can you do for painful swollen gums?
Brush gently with a soft brush and clean between the teeth without forcing an instrument into the swelling. Rinse with warm water, avoid squeezing the lump, and do not apply heat or caustic substances directly to the gum.
When is painful gum swelling an urgent problem?
Arrange urgent care for fever, facial swelling, a bad taste with increasing pain, reduced mouth opening, or difficulty swallowing or breathing. Swelling that persists or recurs should be assessed even if the pain temporarily improves.
What should you ask about painful gum swelling?
Ask whether the swelling is from the gum or the tooth, whether pus is present, which imaging is needed, and how the proposed treatment will prevent recurrence.
Frequently asked questions
Can the symptom disappear without treating the cause?
Yes, symptoms can fluctuate, but temporary relief does not show that decay, infection, or gum disease has resolved.
Will a dental X-ray always be needed?
Not always; the dentist chooses imaging when the suspected tooth, root, bone, or unerupted structure cannot be assessed adequately by examination.
