Swollen gums on bottom left side

One swollen area on the lower left gum may reflect plaque, trapped food, trauma, a tooth problem, or a localized infection.

Gingival swelling is enlargement of the soft tissue around a tooth. Location, redness, bleeding, tenderness, a draining point, and the condition of the nearby tooth help distinguish surface inflammation from a deeper abscess.

Brush the area gently twice daily and floss carefully to dislodge food. Avoid squeezing the swelling or placing irritants on it, and use a warm rinse for comfort while arranging an examination.

Book a dental visit if swelling lasts, recurs, bleeds easily, or is accompanied by tooth pain. Fever, facial swelling, or difficulty swallowing or breathing requires urgent care.

Ask whether the swelling is gingivitis, a periodontal pocket, food trauma, or an infection from the tooth. Ask whether cleaning, a filling, root-canal treatment, or drainage is indicated.
