Swollen and tender gums
Swollen, tender gums often reflect plaque-related inflammation, but food impaction, infection, medicines, or another condition can also contribute.
The short answer
Plaque bacteria trigger inflammation at the gum margin, making gingiva red, puffy, and prone to bleeding. Localized tenderness can also come from food, an erupting wisdom tooth, a crack, or an abscess.
How can gentle cleaning help swollen and tender gums?
Brush with a soft brush and fluoride toothpaste, clean between teeth gently, and rinse with water after food. Do not cut or drain the gum.
When should swollen gums be examined by a dentist?
Book an examination if swelling lasts, recurs, bleeds readily, or affects one tooth. Pus, fever, spreading facial swelling, or breathing difficulty needs urgent help.
What should you ask about the cause of gum inflammation?
Ask whether the inflammation is limited to the gum or linked to a tooth and whether pocket measurements or an X-ray are needed.
