My gum between my teeth is swollen

Food impaction, plaque, calculus, floss injury, a cavity near the contact point, or a periodontal pocket can inflame the papilla. A tooth-root infection may also drain toward the gum and form a tender bump.

Rinse gently with warm water, clean the contact with floss or an interdental brush without forcing it, and avoid squeezing the swelling. Do not place caustic substances on the gum or delay care if pain or swelling grows.

Arrange dental care if the swelling lasts, bleeds, recurs, or is linked to pain, bad taste, or a loose tooth. Facial swelling, fever, or difficulty opening the mouth, breathing, or swallowing needs urgent care.

Ask whether the source is food impaction, gum disease, decay, or a tooth-root infection, and whether you need cleaning, a filling, root canal treatment, or periodontal care.
