Swelling in gum under tooth

A swollen gum under a tooth can result from plaque inflammation, trapped food, trauma, or an infection in the tooth or surrounding tissues.

A lump or swelling beneath a tooth is a change in the gingiva or nearby supporting tissues. The cause may be superficial gum inflammation or a deeper collection of inflammatory fluid associated with the tooth root or periodontal pocket.

Plaque and calculus can inflame the gum edge, while food impaction, a sharp filling, trauma, decay, or a cracked tooth can irritate one area. Tender swelling with drainage, fever, or tooth pain raises concern for an infection that needs dental treatment.

Swelling under one tooth can be superficial gum irritation or a deeper tooth or periodontal infection.

Rinse gently with warm water, brush with a soft brush, and clean between teeth without forcing an object into the swelling. Do not squeeze it or place aspirin on the gum, and arrange an examination to identify the source.

Keep a record of changes and bring the product, appliance, or medication list to the appointment so the clinician can assess the relevant details.

Seek same-day dental care for swelling with fever, spreading facial swelling, severe pain, pus, or difficulty opening the mouth. Go for emergency help if swelling affects breathing or swallowing.

Do not delay assessment when symptoms are escalating, recurring, or affecting eating, sleep, mouth opening, breathing, or swallowing.

Ask whether the swelling comes from the gum, tooth root, or periodontal pocket, whether an X-ray is needed, and whether drainage, cleaning, filling, root canal treatment, or extraction is indicated.

Ask what the examination found, which treatment is intended to address the cause, and how you will know whether the problem is improving.
