Strep throat and swollen gums

Gum swelling may result from plaque-associated gingivitis, food impaction, trauma, a erupting tooth, an abscess, or irritation from an appliance. Throat infection commonly causes sore throat, painful swallowing, fever, and tender neck glands rather than isolated swelling around one tooth.

Brush gently with a soft brush, clean between the teeth, rinse with plain water after food, and avoid squeezing the swelling. A clinician can examine the throat and gums, test for streptococcal infection when indicated, and check the tooth with probing or an X-ray if a dental source is suspected.

Seek prompt dental care for a gum lump, pus, worsening toothache, facial swelling, or fever. Emergency care is needed if swelling affects breathing or swallowing, or if you cannot open your mouth normally.

Ask whether the swelling is centered on the throat, gum, or a particular tooth, whether a dental abscess is present, and which examination or test is needed.
