Gum around tooth swollen and painful
Swollen painful gum beside a tooth can come from plaque, trapped food, trauma, or an infection in the tooth or surrounding tissues.
The short answer
Swollen painful gum beside a tooth can come from plaque, trapped food, trauma, or an infection in the tooth or surrounding tissues. A dentist must examine the tooth, gum pocket, and bite to tell gingival inflammation from a dental abscess or erupting tooth.
What causes swelling in one area of the gum?
The swelling is an increase in fluid and inflammatory tissue in the gingiva, often localized where plaque or debris collects. Pain may also originate inside the tooth and spread toward the gum when decay, a crack, or pulp inflammation is present.
What can I do for a painful swollen gum?
Rinse gently with warm water, brush the area carefully, and remove visible food with floss rather than a sharp object. Use only pain medicines that are suitable for you and follow the label, because pain relief does not remove an abscess or repair a damaged tooth.
When does painful gum swelling need dental care?
Arrange prompt dental care when swelling or pain persists, worsens, recurs, or is joined by fever, pus, a bad taste, or difficulty opening the mouth. Go urgently for facial or neck swelling, trouble swallowing, or breathing difficulty.
Is the swelling coming from the gum, tooth, or restoration?
Ask whether the source is the gum, the tooth pulp, a wisdom tooth, or an infection around a dental restoration. Ask whether an examination, periodontal measurements, vitality testing, or radiographs are needed and which treatment addresses the cause.
Frequently asked questions
Can a swollen gum heal on its own?
Minor irritation may settle after debris is removed, but persistent or painful swelling needs an examination to exclude infection.
Should I pop the swelling?
No. Puncturing it can injure tissue and does not treat the dental source.
